Breakage as well as deflection or incorrect laying of the propeller, intermediate and thrust shafts.

Inspection of boilers installed on ships,

and reflected in the peer review report.

The appraiser very rarely conducts or requires an internal survey or hydraulic testing of the boiler plant, most often only an external survey is required, which consists in checking the condition of the boiler, pipelines and all boiler equipment during operation of the boiler, namely:

Check the water level in the boiler by purging the channels of the gauge glass with steam and water, as well as purging the test taps;

Check the correctness of the drawing of the risks on the plug of the boiler pressure gauge faucet;

Check the operation of nutrient devices (feed pumps, injectors, automatic feeders, cationite filters and other installations) and lower and upper blowdown valves;

By opening the doors of the chimney and fireboxes, make sure that there are no leaks, steaming and bulging in the firing parts accessible for inspection, and also check the condition of the brickwork of the firebox; the design of the chimney and doors should exclude the passage of gases and air leakage;

make sure that the drive for manual detonation of the safety valves, remote drives of the fuel and stop valves are in good condition;

Check the condition of the insulation of the boiler and steam pipelines;

Pay attention to the general condition of fuel storages, fuel lines, fuel pumps, injectors.

During an external survey, it is necessary to check the correct installation and operation of boiler fittings, adjustment and sealing of safety valves;

Check the tightness of the connections of steam pipelines and fittings, make sure that there are no leaks, steaming and boiling that prevent the valves from opening or closing, check the reliability of the operation of remote actuators of stop valves.

When surveying boiler automation, you should:

Check the correct operation of the automatic combustion control and boiler power supply system;

Make sure that the operation of the automation means of other systems and devices servicing the boiler plant, automatic control of the water level in the warm box, automatic ignition of the nozzle, fuel temperature (viscosity) regulators, automatic control of the fuel level in the service tank, etc.;

Check the operation of the means of alarm and automatic protection of the boiler, paying special attention to the operation of the nozzle extinguishing system when the water level drops below the permissible level;

Make sure that all devices that control the operation of the boiler are in good condition.

Assessment of the technical condition of the boiler.

Determination of wear is carried out upon receipt of measurements and inspection, operation is prohibited:

If wear and defects exceed those given in (See Table No. 10) in the column "limited fit";

If there are leaks in the seams that are not amenable to chasing or welding, as well as “wet” cracks in the parts of the boiler, including the lintels of the tube sheets;

In case of warping of tube sheets with a deflection arrow of more than the thickness of the sheet in cases of setting tubes for welding and more than half the thickness of the sheet - in cases of setting tubes using rolling;

When the ellipticity of the holes of the tube sheet is more than 2% of the outer diameter of the pipe;

with unsatisfactory tests and studies of the boiler metal.

Evaluation of pipelines and pressure vessels (tanks, pneumatic tanks for sanitary and other systems) installed on ships,

Internal survey and hydraulic tests are carried out by the inspection about which the relevant acts are drawn up. The appraiser performs an external survey of pressure vessels and pipelines in order to check the condition of the external surfaces.

The presence and condition of safety devices and control devices, the tightness of the connection of individual parts of the valve.

Safety valves must be adjusted so that the excess pressure in the vessel when the valve is actuated does not exceed 10% of the working pressure. Safety valves installed after pressure reducing valves must be adjusted to a pressure exceeding the operating pressure by 0.1-0.2 MPa.

After each operation, the safety valve must close at a pressure of at least 85% of the working pressure.

If the safety valves fail, the pressure vessels are not allowed to work. (The shipowner must provide annual air test reports).

General approaches and techniques that are used in the evaluation of ships, depending on the purpose of the evaluation.

In the expert evaluation of ships, depending on the purpose of the evaluation, three generally recognized methods of evaluation are used:

1. For purchase and sale agreements, redemption:

Sales analogue method

Cost method.

2. For entering into UV enterprises, rent:

Sales analogue method

Profitability valuation method (by business).

3. For auctions, competitions:

Cost method

Yield method.

4. Merger and division of business partnerships with all forms of ownership:

Analog sales method;

Yield method:

cost method.

5. When pledging, insurance

Analog sales method (30-50%) of the cost

6, When selling for scrap metal, write-off.

The cost method, taking into account the coefficients of economic depreciation, when selling at a residual value to non-residents of Ukraine, it is necessary to take into account the permits issued by the relevant services for the export of non-ferrous metals. (more often sold as fit or limited fit).

When determining the method of analogues sales must be taken into account!. Date of sale - fluctuation rate of hard currency;

Season (spring, summer, winter, autumn)

Demand and supply market;, the cost of export customs duties, restrictions on the export of ships.

Offers on world markets - quotation.

When determined by the Cost Method:

replacement cost, all types of depreciation (mainly physical depreciation), residual value are determined. Economic depreciation is determined for the valuation of vessels for which there are buyers and the valuation is made to order.

I. INTRODUCTION

These Recommendations, which determine the technical and navigational characteristics of pushed convoys, help to improve the safety of navigation and contribute to the creation of favorable conditions for the development of pushing navigation. They summarize the experience gained by the Danube countries in the field of pushing navigation and which serves as the basis for uniform minimum standards and other requirements due to the need to ensure the safety of navigation.

II. MAIN PROVISIONS

2.1 Purpose and scope

2.2 Terms and Definitions

2.3 Relationship with current documents and OPPD

The provisions of these Recommendations are in full conformity with the DFID and local regulations established by the Danube states and special river administrations, as well as with other applicable documents on pushing navigation. The provisions of these Recommendations derive from the provisions of the aforementioned documents and contribute to their uniform application.

III. TECHNICAL AND NAVIGATIONAL STANDARDS FOR PUSHED CONSTRUCTIONS

The pusher must always have sufficient power and maneuverability to ensure the safe navigation of the pushed convoy up and downstream; the pusher must have such technical and navigational characteristics that it does not create difficulties for the movement of other vessels, especially when passing difficult sections (bends, rifts, bridges), as well as when overtaking, passing and stopping.

3.1 Minimum speed

The pusher must be able to ensure a minimum speed of the train relative to standing water of at least 12 km/h.

This requirement is not mandatory for pushers, who only work in ports and raids.

3.2 Stopping distance and time

The power of the pusher must ensure the possibility of a complete stop of the pushed convoy in relation to the shore, subject to the following conditions:

The distance traveled before the train stops must not exceed:

When moving up against the current: 200 m or 1 train length;

Downstream: 600 m or 3 train lengths.

The stopping time of the train should not exceed:

When moving up against the current: 3 minutes;

Downstream: 6 minutes.

3.3 Driving forward

The pushed convoy must have good forward controllability, which is ensured by the pusher's ability to maintain a straight course of the convoy and, if necessary, quickly change it. Rudder shift from 40 on one side to 35 on the other side using the main steering gear should not exceed 28 seconds at maximum speed.

3.3.1 Ability of the pusher to keep the convoy straight ahead

The time of keeping the selected course of the composition without the use of rudders should be on average at least 1 minute.

To keep the composition on the required course for 5 minutes, the number of necessary course corrections should not exceed 5.

3.3.2 The ability of the pusher to quickly change the course of the convoy

The time for the train to deviate from the straight course by 10 and return to the original straight course as a result of the rudder shifted to deviations up to ±20 should not exceed 5 minutes when swimming upstream. In case of deviation, the distance along the width of the course should not exceed 0.4 of the train length.

3.4 Handling in reverse

The pushed convoy must be adequately steered astern and move in the desired direction, both when maneuvering to stop and during prolonged reverse movement due to navigational needs.

3.5 Lateral movement ability

The pusher, if possible, should be able to provide lateral movement of the train in a direction perpendicular to its axis, the need for which may arise when passing through narrows, rifts, bridges, locking, passing, maneuvering in ports, as well as in emergency situations.

3.6 Turn time and area

The turnaround time of the composition by 180 should be no more than 10 minutes. The train turn area should not exceed 1.5 train lengths in width, and the drift with the flow - 3.5 train lengths. In this case, all means of ensuring a turn maneuver are used.

TESTING METHODS FOR PUSHED CONSTRUCTIONS

These Test and Measurement Methods for Determining the Technical and Navigational Characteristics of Pushed Convoys, contained in Chapter III of the Recommendations, are intended to establish uniform principles for conducting full-scale tests of pushed convoys.

Prior to testing, the main initial data characterizing the pushed convoy and navigational conditions of the testing site are determined.

During the tests, at least two measurements of the determined parameters are carried out and the average values ​​for each characteristic are calculated. Based on the results of the tests, an analysis of the results obtained for each characteristic is carried out and their final values ​​are determined for a given or typical pushed convoy.

A. Initial data characterizing the navigation conditions at the test site

The test site for field tests is selected in such a way that the river section is straight for a sufficient length, has a uniform flow and sufficient width and depth of the fairway. Tests are carried out, whenever possible, in calm weather or winds not exceeding 2 on the Beaufort scale.

The test site is equipped on the shore with secant and, if possible, leading leading marks or buoys equipped with radar reflectors. The secant leading signs are placed at certain exact distances.

The characteristics of the navigational conditions at the test site should include:

Location of the section (from … km to … km) of the river and its length;

Date (day, month, year and time of testing);

Weather conditions, visibility, wind speed and direction;

Water level at the nearest water gauge;

The average speed of the flow of water;

Average fairway width;

The average depth of the fairway.

IN. Initial data characterizing the pushed convoy

Full-scale tests are carried out with pushed convoys navigating in this section, if possible, with maximum dimensions determined on the basis of practical experience, depending on navigation conditions, as well as the power and maneuverability of the pusher, subject to the conditions of safe navigation. In areas where there are regulations on the dimensions of pushed convoys, the dimensions of the pushed convoy must not exceed the prescribed maximum dimensions. The shape of the mooring, the number of units and the amount of cargo should be chosen depending on the direction of sailing upstream or downstream.

Vessels in a pushed convoy during the test shall, as far as possible, be of the same type and have the same draft.

Characteristics of the pushed train:

Scheme of the pushed train;

Dimensions of the pushed train (L max , B max);

Displacement, carrying capacity and amount of cargo of the pushed train;

Pushed vessel data (L max , B max , T moy.effectif , D effectif , Q);

Pusher data (L max , B max , T max , N).

WITH. Test methods for individual technical and navigation characteristics of pushed convoys

Measurements of the distances and position of the pushed convoy during tests can be made using leading signs located on the shore, or by a photoradar method based on photographing the image on the screen of the pusher's radar installation at certain intervals, or by another method that ensures the measurement accuracy of ± 10 m.

1. Travel speed

The speed of the pushed convoys is measured both when swimming upstream against the current and downstream; the following provisions are taken into account:

a) Preparation before the test:

The section of the run should, if possible, be at least 2 km long;

Prior to the start of measurements, the pushed convoy must cover a distance of 1 km at full power of the pusher engines;

When shifting the rudders of the pusher during the tests, the deflection of the rudder shall not exceed ±5º.

b) Measured quantities:

Distance traveled;

Time to travel this distance;

Turnovers of the main mechanisms.

    1 Regulations on the Classification of Inland and Mixed (River-Sea) Navigation Vessels “Regulations on the Classification of Inland and Mixed (River-Sea) Navigation Vessels” is a regulatory legal act that determines the procedure for carrying out classification activities by the Russian River Register. The document was developed on the basis of Part 1 "Classification" of the Rules for the Classification and Construction of Inland Navigation Vessels (PSVP), other Rules of the Russian River Register, ed. 1. GENERAL PROVISIONS 1.1. This Regulation determines the procedure for classifying ships of inland and mixed (river-sea) navigation (hereinafter referred to as classification activities) by the federal state institution "Russian River Register" (hereinafter referred to as the River Register). In its classification activities, the River Register is guided by this Regulation, the rules developed and issued by it, containing requirements for ships during their design, construction, repair and operation, as well as for materials and products intended for installation on ships, and other regulatory and technical acts (hereinafter referred to as the rules) 1.5 of this Regulation, in accordance with their purpose, the protection of life and health of passengers and ship crews, the safety of cargo carried on ships, the environmental safety of ships To achieve the goal specified in 1.3 of this Regulation, the classification de Activities include the development and publication of rules, review and approval of technical documentation, technical supervision of the manufacture of materials and products, the construction of ships with the assignment of a class, as well as confirmation, renewal and restoration of the class based on the results of surveys prescribed by the rules for the entire period of operation of each ship prior to its write-off with execution and issuance of relevant documents. Classification activities of the Russian River Register are self-propelled inland navigation vessels with main engines with a power of at least 55 kW, non-self-propelled vessels with a capacity (Appendix 1 to this Regulation) of at least 80 tons, all passenger and tankers ships, ferry crossings and floating bridges on inland waterways, ships of mixed (river-sea) navigation (clause 1 of Article 35 of the Code of Inland Water Transport of the Russian Federation) At the request of organizations, the River Register may carry out classification activities in relation to objects not listed in paragraph. 1.5 of these Regulations Works performed by the River Register within the framework of classification activities are carried out on a reimbursable basis Organizations engaged in the design, construction, re-equipment, modernization and repair of ships, manufacture and repair of products and manufacture of materials for installation on ships, performing work, the results of which are used by the River Register The Register during surveys, as well as testing laboratories, receive from the River Register a recognition certificate certifying that this organization manufactures products, performs work and/or provides services in accordance with the requirements of the rules. Surveys of organizations for this purpose are carried out by the River Register once every two years.

    2 2. PROCEDURE FOR APPLICATION OF RULES 2.1. Vessels, materials and products, the technical documentation of which is submitted to the River Register for approval after the entry into force of the rules or changes made to the rules, must comply with the requirements of these rules and changes. For ships under construction, materials and products, the technical documentation for which was approved by the River Register before the rules came into force, the version of the rules that was in effect at the time of approval of this documentation is applied, unless otherwise specified in the relevant parts or sections of the rules. Vessels in operation are subject to the requirements of the edition of the rules according to which they were built, unless otherwise specified in subsequent editions of the rules and bulletins of additions and amendments to the rules issued after the publication of the rules. to the extent that it is expedient and technically justified, the River Register in some cases may allow the use of structures, materials and products, as well as make decisions that, to one degree or another, do not meet the requirements of the rules, provided that it is provided with the necessary justifications (calculations, results experimental studies, operating experience and other data) proving that the specified designs, materials, products or decisions are no less effective from the point of view of safety than those regulated by the rules If the design of the ship, its components or the materials used cannot be recognized sufficiently proven in operation, the River Register may propose special tests, reduce the period between periodic surveys, increase the scope of these surveys, or impose restrictions on the ship's operating conditions. Restrictions are lifted after obtaining satisfactory test results during operation The River Register has the right, in case of non-compliance with the requirements specified in the rules, to prohibit the operation of ships, ship mechanisms, devices and technical means, and also not to issue or cancel documents permitting the operation of ships previously issued by it. 3. CONSIDERATION AND APPROVAL OF TECHNICAL DOCUMENTATION 3.1. The River Register reviews and approves the technical documentation for the construction, re-equipment, modernization and repair of ships, the manufacture and repair of products and the manufacture of materials for installation on ships (technical designs, working documentation, specifications, standards and other regulatory and technical documents), and also approves computer programs used for the purposes of designing and operating ships. Typical lists of technical documentation submitted for approval to the River Register are given in the rules. Technical documentation is developed and submitted for consideration prior to construction (manufacturing) of the facility. Documents are submitted to the River Register in the form of originals, duplicates or copies. The documents must contain all the necessary data to verify compliance with the requirements of the rules. In case of application of fundamentally new solutions, the River Register may be submitted for consideration the terms of reference, technical proposal, draft design, as well as experimental design and research studies. Such documents are not subject to approval. Based on the results of their consideration, a Letter of Conclusion (review) of the River Register is drawn up. Approval of technical documentation by any structural subdivision of the River Register is valid for all other subdivisions of the River Register. This agreement can be (if there are grounds) canceled or changed only

    3 by the subdivision that approved the documentation, as well as by a higher (by subordination) structural subdivision, the Technical documentation approved by one of the River Register subdivisions is accepted by other subdivisions for technical supervision without additional approval, if the production conditions in a particular organization do not require adjustment of this documentation Changes made to the previously agreed technical documentation must be agreed with the structural subdivision of the River Register that reviewed the technical documentation. Changes made to the working documentation in the process of its development are approved by the River Register inspection (hereinafter referred to as the inspection) that approved the working documentation. All deviations from the agreed working documentation that occurred during the construction of the ship, the manufacture, repair of the product or the manufacture of material for installation on ships, are agreed by the inspection supervising the construction of the ship, the manufacture or repair of the product or the manufacture of the material, respectively. However, this inspection retains the right to submit certain deviations of a fundamental nature for approval to that subdivision of the River Register that considered the project. The River Register does not check the correctness of performing computational operations in the calculation, including according to the programs agreed with the River Register, but considers the final results of the calculations. The calculations must be carried out in accordance with the instructions of the rules or methods agreed with the River Register. In some cases, the River Register may conduct an additional examination of the reliability of the final results of calculations. If there are solutions in the technical documentation that differ from those regulated by the rules (derogations), the design organization shall submit a list of such solutions with a statement of their essence and technical justifications. In its opinion on the project, the River Register informs on the decisions made on the list presented. Deviations not included in the list are not considered agreed, and the River Register may require their elimination at any subsequent stage of design, construction or manufacture of facilities. All documentation submitted to the River Register for consideration is confidential and can be transferred to a third party only with its written consent. owner The period of validity of the approval of the River Register for the technical documentation of the vessel is no more than 6 years. After this period, or in the event that the interval between the dates of approval of the documentation and the start of construction exceeds 3 years, the documentation is subject to adjustment in order to take into account changes in the rules that have occurred during the specified time. In justified cases, the River Register may extend the period of validity of the technical documentation without its adjustment. The scope of the adjustment must be agreed with the River Register. As a rule, approval of technical documentation for the repair, modernization and re-equipment of ships is carried out without a time limit. The approval of standards and other regulatory documents, with the exception of technical specifications for materials and products, is carried out by the River Register for the period of their validity. Specifications are agreed for 6 years. At the end of the validity period, the documentation is subject to agreement with the River Register, during which its compliance with the requirements of the current rules is checked. 4. TECHNICAL SUPERVISION 4.1. Technical supervision is an integral part of the classification activity and includes step-by-step checks of compliance with the rules in the process of building, re-equipping, modernizing, repairing ships and their elements, manufacturing and repairing products (mechanisms, equipment, devices, supplies) and manufacturing

    4 materials for installation on ships. The elements of the ship include the structural parts of the ship regulated by the rules: hull, superstructures, ship devices, equipment, supplies, fire protection equipment, engines, boilers, systems, heat exchangers, pressure vessels, deck machinery, electrical equipment, radio and navigation equipment, refrigeration units, automation equipment, hoisting devices, environmental safety equipment Technical supervision of the River Register is carried out at the request of organizations on a contractual basis taking into account specific production conditions. The contract is accompanied by a list of control checks of objects and technological operations that are mandatory for the presentation of an inspection after the control by the organization's personnel and execution of the relevant documents by them. documentation, including product quality control documents, as well as the necessary tools and overalls; 2) prepares facilities for inspections to the extent required; 3) ensure the safety of technical supervision by the inspector; 4) ensure the presence of officials authorized to present objects to the inspector for inspections; 5) notify the inspector in a timely manner of the time and place of inspections and testing of objects. If the organization fails to comply with the conditions for conducting technical supervision, the inspector has the right to refuse inspections and participation in tests, having justified his refusal in writing, the River Register may instruct the technical personnel of the organization to conduct control tests or part of them in order to verify the compliance of materials and products with the rules. In this case, the rights and obligations of the organization and the River Register are established by agreement of the parties Materials and products (objects of technical supervision, see clause 4.3 of these Regulations) are allowed to be installed on ships only if documents of the River Register or documents of another classification organization issued on behalf of the River Register are available. Register. In the absence of such an instruction, the possibility of recognizing certificates of another classification organization is the subject of special consideration by the River Register, 4. 7. By agreement with the Head Office of the River Register, instead of issuing documents of the River Register, it is allowed to confirm the documents of the manufacturer's organization for materials and products of mass production, including spare parts, by signing them by the inspector and setting his personal stamp New and for the first time presented to the River Register standard materials and products must be approved by the River Register for their intended use with the issuance of a certificate of approval of a type material or product in the manner prescribed by the rules. 5. SURVEY OF SHIPS IN OPERATION 5.1. Inspection of ships in service is an integral part of the classification activity, consists in checking the ship's compliance with the rules and includes at least: checking the availability of agreed technical documentation, certificates for materials and components, certificates of the organization's technical control service, certificates of the shipowner, certificates of previous surveys;

    5 visual inspection, measurements, operation and testing; registration and issuance of documents by the River Register Each ship specified in paragraph 1.5 of these Regulations is registered with the inspection: 1) after the ship has been built; 2) after changing the home point and, in connection with this, moving to the area of ​​activity of another inspection; 3) upon transfer to the class of the River Register from the class of another classification organization; 4) if the ship was previously deregistered or was not registered with any inspection; 5) in case of change of the shipowner The removal of the ship from the classification register of the inspection is carried out: 1) when decommissioning; 2) when relocating to a new home base in the area of ​​activity of another inspection; 3) upon transfer to the class of another classification organization; 4) in the case when the ship has not been presented for survey for more than two years in the absence of a justified request of the shipowner; 5) when changing the shipowner. Removal of the ship from the inspection register, except for the case specified in paragraphs. 4 of paragraph 5.3, is carried out at the request of the shipowner, which must indicate the reason for deregistration of the vessel The shipowner submits the vessels registered with the River Register for survey within the time periods specified in the documents issued to the vessel by the River Register Inspection of ships, except for calls in case of emergency, it is carried out according to preliminary applications sent to the inspector or to the inspection at least a day before the survey. The inspector may refuse to survey if the ship or its element is not prepared for the survey. In this case, the inspector must state in writing (in an act or notice) the reasons for the refusal. For all types of surveys, the inspector is authorized to make decisions in accordance with the rules. Decisions that differ from those regulated by the rules must be agreed with the head of the inspectorate. The ship must keep a certificate of verification by the shipowner of the suitability of the ship for operation before starting navigation. the work necessary to determine the technical condition of the ship's elements (complete or partial dismantling of the structure, opening of the slats, lining and insulation, determining the parameters of wear and deformation, calculations, measurements, etc.) are carried out by and/or at the expense of the shipowner. In justified cases, the shipowner may, and in the cases prescribed by the rules, is obliged to entrust the fault detection of one or another element of the ship to an organization that has a certificate of recognition for the corresponding type of activity issued by the River Register. In case of discrepancy between the results of the selective control carried out by the inspector and the measurement data provided by the shipowner, the inspector has the right to demand that all necessary measurements be repeated. Adjustment and sealing of the safety valves of boilers and pressure vessels is performed by the shipowner. During all types of surveys, the shipowner and / or the ship's officers inform the inspector about all the defects noticed, cases of failure of the elements of the ship between the previous and ongoing surveys, as well as changes in the composition

    6 equipment and supplies and repairs carried out in the same period, present the necessary documents, certificates of previous surveys, technical documentation and certificates of inspections and tests of ship elements prescribed by the rules. On damage to the ship, the shipowner immediately notifies the inspection, within the boundaries of which the damage occurred, and presents the ship for examination, regardless of whether the damage led to a traffic accident or not. The inspection may not conduct a survey if the damage did not lead to a transport accident, decommissioning of the ship and can be eliminated on board in a short time passage in accordance with the requirements of the rules under the technical supervision of the River Register with issuance of a certificate for a one-time passage. with the requirements of the rules, the availability of information on the ship's stability and floodability The ship may be recognized by the River Register as suitable for the carriage of goods not stipulated by the ship's documents, if the shipowner submits technical documentation, confirming the possibility of safe transportation of this cargo and containing a description of additional design measures, methods of securing the cargo, additions to the instructions for loading and unloading, as well as information on the stability and floodability of the ship, Any changes related to materials, products and ship design, which are subject to the requirements rules are agreed with the River Register prior to their implementation. 6. DOCUMENTS OF THE RIVER REGISTER 6.1. When carrying out classification activities, the River Register issues documents prescribed by the legislation of the Russian Federation and the rules. The River Register documents are issued based on the positive results of the survey of the object. Main Directorate of samples of forms, stamps and seals In case of disagreement with the decision of the inspector, the shipowner or organization may appeal to the head of the inspectorate. The decision of the head of the inspectorate may be appealed to the Main Department of the River Register with the submission of justifications and a copy of the decision of the head of the inspectorate. The decision of the Main Directorate may be appealed to the federal executive authority in the field of transport or the arbitration court. 7. PRINCIPLES OF THE CLASSIFICATION OF VESSELS 7.1. The class of a ship is determined by a set of conventional symbols assigned to a ship during its classification and characterizing the design features of the ship and the conditions of its operation in accordance with the rules based on safety requirements. The classification of ships is carried out in accordance with the classification of water basins. are classified according to the categories "L", "R", "O" and "M" depending on their wind wave regime based on the following conditions: 1) in the pools of discharges "L", "R" and "O" waves 1% - height security

    7, respectively, 0.6, 1.2 and 2.0 m have a total repeatability (probability) of no more than 4% of the navigation time; 2) in the pools of the "M" category, waves with a 3% probability of a height of 3.0 m have a total repeatability (probability) of no more than 4% of the navigation time. Estuary sections with a maritime navigation regime start from the border of inland waterways. In these sections, the operation of vessels of all types is allowed in accordance with the rules and class of the vessel. Lists of inland water basins of Russia, depending on their category, as well as sea areas in which the operation of ships of mixed (river-sea) navigation is allowed, and the conditions for the operation of ships are established by the rules. The main symbols in the formula for the class of inland navigation ships are the letters "L", "R ”, “O” and “M”, which determine the design features of the vessel and the category of the water basin in which its operation is allowed. The main symbols in the formula for the class of vessels of mixed (river-sea) navigation are the letter combinations "O-PR", "M-PR" and "M-SP", which determine the design features of the vessel and the conditions of its operation in sea areas. Characteristics of the standard wave heights in relation to the main class symbol of the ship are given in Appendix 2 to these Regulations Depending on the design features of the ship, the main class symbol in the class formula is supplemented with the following symbols: 1) for ships built under the technical supervision of the River Register or another classification recognized by the River Register organization, a symbol that is placed before the main symbol, for example, "O"; 2) immediately after the main symbol of the class, the wave height allowed during operation in meters is entered with an accuracy of the first decimal place, for example, "01.5". For high-speed vessels: gliders, hydrofoils (HPV), hovercraft (Hovercraft), as well as ekranoplans, wave height restrictions are written as a fraction, the numerator of which indicates the wave height when the vessel is moving in a displacement state, and the denominator in operational mode. After the fraction, the type of vessel is indicated according to the principle of movement, for example, “Р1.2 / 0.8 glider”, “О2.0 / 1.2 SPK”, “О2.0 / 1.5 SVP”, “Р 1.2 / 0.4 ekranoplan"; 3) for ships with special ice reinforcements, after the wave height value, the word “ice” in brackets and the thickness of finely broken winter ice in centimeters, established by the River Register when agreeing on the ship’s design, are written, for example, “O (ice 20)”. The word "icebreaker" is introduced into the formula for the class of icebreakers; 4) for ships equipped with automation equipment in accordance with the rules, after all the symbols specified in subparagraphs 1 3 of this paragraph, the letter “A” is entered, for example, “O 2.0 (ice 20) A”; 5) if the ship or its individual elements do not fully comply with the rules, have not been tested by operational practice, but are admitted to operation by the River Register as experimental for the purpose of their study and verification, the symbol “E” is entered in the class formula before the symbol, for example, “E O2.0 (ice 20) A". If the results of tests, operation and surveys of a ship with an experimental class are satisfactory, the symbol “E” may be excluded from the class formula The River Register may exclude or change this or that symbol in the class formula in case of a change or violation of the conditions that served as the basis for introducing this symbol into the class formula River The Register assigns a class to a ship during the initial survey, confirms, renews or restores it during other types of surveys. Assignment, renewal or restoration of a class to a ship is certified by a classification certificate issued to the ship. The class of a ship permanently operated in a basin of a given category must not be lower than the category of this basin. V

    8 basin of a higher category, subject to the fulfillment of additional requirements for the design, freeboard, equipment, supplies, as well as restrictions on the navigation area, wind and wave regime, seasonality, ice conditions, etc. The River Register, at the request of the shipowner, reclassifies ships in case the need to change the main symbol of the class in the formula of the class or type and purpose of the ship Works to prepare the ship for reclassification with an increase in class and / or in connection with a change in the type and purpose of the ship should be carried out in accordance with the technical documentation agreed with the River Register, and under its technical observation. Calculations and checks should be carried out in accordance with the rules in force at the time of the development of the technical documentation for reclassification, and should be focused on new operating conditions due to changes in external loads, technical characteristics (draft, displacement, freeboard), type of cargo carried and etc.

    9 APPENDIX 1 GUIDELINES FOR DETERMINING TOWNTIME Tonnage is the gross tonnage of the vessel. Gross tonnage of inland navigation vessels GT in registered tons is determined by the formula: GT = V / 2.83, where V is the gross tonnage, m 3, determined by measuring all the premises of the vessel or calculated by the formula: V LBT LB (H T), lbh where L and B the length and width of the vessel along the design waterline, m; H side height, m; T draft of the vessel along the design waterline, m; coefficient of completeness of displacement; coefficient of completeness of the design waterline; l, b, h respectively mean length, width and height of superstructures or deckhouses, in m. Gross tonnage does not include the volume of the wheelhouse, galleys, lavatories, all skylights and similar small deckhouses. The gross tonnage of ships of mixed (river-sea) navigation is determined in accordance with the rules for measuring ships contained in Appendix 1 to the International Convention on the Measurement of Ships, 1969.

    Ship's documents must be kept on the ship, and when ships are operated without crew, they must be kept by the owner of the ship.

    The captain (commander, skipper) of the vessel, the owner of the vessel (when operating vessels without crews) are responsible for the safety of all documents of the River Register.

    Any changes related to materials, ship design and products to which the requirements of the rules apply, carried out by shipowners, shipyards and manufacturers, must be agreed with the River Register before they are implemented.

    Supervision over the construction, operation and refurbishment, modernization and re-equipment of ships is carried out by inspectors on the basis of approvals from the River Register of technical documentation.

    The following vessels of inland and mixed navigation, both under construction and in operation, owned by state enterprises, of any form of ownership, business partnerships, public organizations and individuals, are subject to technical supervision by the River Register:

    - self-propelled with main mechanisms with a power of 55 kW or more;

    - non-self-propelled with a gross tonnage of 80 register tons or more;

    - ship lifting devices with a lifting capacity of 1 t and

    more.

    Technological and special devices of fishing vessels,

    fishing, cable, technical and special-purpose fleets are not subject to supervision by the River Register, except for the equipment listed in the relevant parts of the rules.

    Vessel class

    1.1 The River Register may assign a class to a ship built under its technical supervision, as well as assign or restore a class to a ship in service.

    1.2 Assignment or restoration of a class means that the ship fully or to the extent recognized by the River Register as sufficient satisfies the requirements of the Rules that apply to it.

    1.3 Assignment or restoration of a class to a ship is certified by the issuance of a certificate of seaworthiness and is confirmed during regular annual and extraordinary surveys.
    The main symbol in the formula for the class of an inland navigation vessel is the letter designation "L", "R", "O", "M", which determines the design of the vessel and the category of the water basin in which the operation of the vessel is allowed.
    Depending on the design features of the ship, the main symbol of the class is supplemented by the following symbols included in the class formula:

    For ships built under the technical supervision of the River Register or another classification body recognized by the River Register, the sign * , which is placed in front of the main character, for example "* O"

    For ships with special ice reinforcements that meet the requirements of the Rules, the word “ice” is enclosed in brackets, and for icebreakers, the word “icebreaker” is put instead of ice.

    For vessels recognized by the River Register as experimental, the letter "E" which is placed in front of the combination of the sign * s and the main symbol

    "L", "R", "O", "M", for example "E * M".
    An experimental class is assigned to ships. Some elements of which or the ship as a whole do not comply with the Rules, have not been tested by operational practice, but are allowed to sail by the River Register in order to study new elements of the ship.
    - For ships equipped with automation in accordance with the requirements, the letter “A” is put, which is placed at the end of the class formula, for example “*O (ice) A”. In the class formula of ships intended for navigation in conditions different from the regulated ones, additional signs applied.
    Type and purpose of the vessel.
    The type of vessel should be indicated by the words “motor ship”, “steamer”, “diesel-electric ship”, “Open (closed) cargo ship”, “floating crane”, etc.

    To determine the purpose of the vessel, it is allowed to use additional explanations, for example, transportation of petroleum products with a flash point of 45 0 ., dredging, cargo lifting, etc.

    The type and purpose of the vessels are not included in the class formula, but they are usually indicated in the section "Basic technical data of the vessel" of the Certificate of seaworthiness.
    Regular surveys are carried out in order to determine the technical condition of the main elements of the ship, equipment, devices, systems, supplies. According to the results of the next survey, requirements are presented aimed at ensuring the safety of navigation of the ship in accordance with its purpose and class. (Periodicity in tables)

    (Annual and extraordinary survey.)

    Classification of water basins
    division of water basins into categories "L", "R", "O", "M" carried out under the following conditions:

    In the discharge pools "L", "R", "O", waves of 1% security with a height of 0.6, respectively; 1.2; and 2m have a total repeatability (security) of no more than 4% of the navigation time;

    In the discharge pools "M» Waves of 3% probability with a height of 3m have a total repeatability of no more than 4% of the navigation time.

    In discharge pools "L", "R", "O", "M" vessels corresponding to the categories of classes are allowed to sail with waves with a height of 0.6, respectively; 1.2; 2 and 3m.

    The class of a vessel operating permanently in a basin of a given category must not be lower than the corresponding category of this basin.

    The possibility of a one-time passage through basins that do not correspond to this class of vessels is determined by the Inspectorate, taking into account the wind wave characteristics, the route of the passage and the technical condition, subject to the presentation by the owner of justifications and measures that guarantee the safety of the passage.

    The categories of inland water basins of Ukraine are presented in the order of Ukrmortekhnadzor in addition to the Rules.

    Technical documentation of the ship being converted or restored.

    This is especially important when evaluating ships transferred as collateral for obtaining loans for re-equipment or restoration, or when calculating the LNEI of a ship.
    Prior to the start of overhaul or refurbishment, modernization or re-equipment of the ship, the River Register shall be submitted for consideration the technical documentation on those parts of the hull, mechanisms and equipment of the ship that are subject to repair, modernization, re-equipment or restoration.

    When changing the characteristics of strength, stability, hull design, installing new mechanisms and devices on the ship, etc. as a result of the re-equipment of the ship, approvals from the River Register must be obtained.

    Rules for the inspection of the vessel by the appraiser or (items described upon receipt of the conclusion of the surveyor's survey).
    When inspecting the ship, the following definitions of the main elements of the ship were adopted:

    1. hull - outer plating, deck, platform and inner bottom plating, impervious longitudinal and transverse bulkheads, inner sides, longitudinal and transverse set (bottom, deck, side) superstructures involved in the general bending of the ship, superstructures of passenger ships.


    1. mechanisms main engines, transmissions from them to the propeller shaft, shaft lines, lifting devices of floating cranes, refrigeration units of refrigerated ships, main steam boilers;

    1. Electrical equipment - main electrical machines of an electric propulsion plant, autonomous generators of a general ship power plant, main switchboards, main current cables of ships with electric propulsion plants, power cables from power plant generators to switchboards, from switchboards to electric motors of the main mechanisms of floating cranes and to the electric motors of the refrigeration unit of refrigerated ships.

    1. Equipment, technical safety and supplies - life-saving equipment for ships, emergency and navigational equipment, signaling equipment, fire-fighting equipment, radio communications,

    The scope of the survey, information about the technical condition of the main elements, data on measurements and the amount of repairs and replacements carried out with sufficient completeness should be reflected in the acts examinations.

    Hull and superstructure
    If the vessel is inspected by an appraiser after the first survey by the Inspectorate, then this can be carried out without a diving team, if during the inspection of the compartments and places most subject to wear, defects and damage to the underwater part of the hull are not found.

    During examination superstructures special attention should be paid to regulated elements: closures, doors, windows, ladders, coamings, fire bulkheads, etc.
    The rates of wear of superstructure ties involved in the general bending of the ship should be taken the same as the rates of wear of the hulls. The wear rates of superstructure ties of passenger ships that do not participate in the general bending of the ship should be taken the same as the wear rates for the ends of the hull.
    When the wear of superstructure links exceeds the established norms, it is necessary to reduce the assessment of the technical condition of the hull.

    Particular attention in the assessment with mandatory reflection in the report during the inspection of the superstructure should be reflected damage that affects the safety of navigation.

    When surveying steel docks by the shipowner The appraisal company itself can present in the report an act of diving inspection of the underwater part of the hull and an act on measurements of residual thicknesses with a thickness gauge.

    The appraiser must pay attention on acts of sticking and fault detection of the ship (Two years without a survey on the slipway may be an inland navigation vessel;

    one year - for ships of the class "M-SP", "M-pr", "O-pr".)
    The greatest wear of the links to which you need to pay attention when evaluating the hull or in the acts of surveyor survey is:

    - dial plane - for laying decks and the second bottom of ships, loading, unloading and cleaning of which is carried out by grabs and bulldozers, for the side plating of ships operating in ice conditions and lock basins, for the bottom plating of ships, the hull material of which is subject to path corrosion, for the bow formations of ships, operated in ice conditions and moored near an unequipped shore;

    -upper part of the gas zone - for laying decks and shafts, for deck framing and bulkheads of oil tankers, especially in cargo receiving and unloading compartments.

    -zones of intensive steam-air exchange - for ballast compartments, especially for ships operating in sea and coastal sea areas;

    -bow stern valances especially for ships with toboggan ends.

    In the expert assessment, especially for the conclusion of sales contracts when the vessel continues to operate as intended, it is necessary to indicate the degree of wear of the hull bracing groups, the deformation parameters, on the basis of which the assessment of the technical condition of the hull is established.

    When examining the hull bottom slats, insulation of hold spaces and internal wooden planking should be removed to the extent necessary to determine wear and damage to all elements of the hull, access should be provided for inspection of the deck set. All cement seals, as well as temporary duplicate sheets installed without complying with the requirements of the standards, must be removed or must be noted in the report by the appraiser. Duplicate overlay strips to increase the overall strength of the hull or local strength of individual bonds, as well as doublers installed on pre-welded cracks, are not subject to removal, but can be noted in the report in the descriptive part.

    When inspecting metal ships by an appraiser, the following parts of the hull and superstructures should be selectively inspected:
