Clasifications Register Rules and Regulations - Rules and Regulations for the Classification of Inland Waterways Ships, July 2022 - Part 5 Main and Auxiliary Machinery - Chapter 11 Ship Piping Systems - Section 1 General requirements

Section 1 General requirements

1.1 Application

1.1.1 The requirements of this Chapter apply to piping systems on all types of Inland Waterway Vessels except where otherwise stated.

1.1.2 Special attention is drawn to National and International technical and operational requirements of countries where the ship is registered or operating and which are outside classification as defined in these Rules.

1.1.3 Consideration will be given to special cases or to arrangements which are equivalent to those required by these Rules. Consideration will also be given to the pumping arrangements of small ships and ships to be assigned class notations for special services.

1.1.4 The Rules for bilge systems for dry cargo vessels carrying dangerous goods have been derived from requirements of the European provisions concerning the international Carriage of Dangerous Goods by Inland Waterways ADN which assume heavy traffic on relatively narrow waterways through heavily populated areas. ADN is an abbreviation from Accord européen relative au transport international des merchandises Dangereuses par voie de Navigation intérieure. See also Pt 4, Ch 1, 12 Additional requirements for ships carrying dangerous goods.

1.1.5 Where a DG notation is to be assigned, the requirements of this Chapter andPt 4, Ch 1, 1.3 Class notation 1.3.5, are to be complied with.

1.1.6 Piping design is to comply with Pt 5, Ch 10 Piping Design Requirements as applicable.

1.2 Prevention of progressive flooding in damage condition

1.2.1 For ships to which subdivision and damage stability requirements apply, precautions are to be taken to prevent progressive flooding between compartments resulting from damage to piping systems. For this purpose, piping systems are to be located inboard of the assumed extent of damage applicable to the requirements of the Flag Administration.

1.2.2 Where it is not practicable to locate piping systems as required by Pt 5, Ch 11, 1.2 Prevention of progressive flooding in damage condition 1.2.1, the following precautions are to be taken:

  1. Bilge suction pipes are to be provided with non-return valves of approved type.

  2. Other piping systems are to be provided with shut-off valves capable of being operated from positions accessible in the damage condition, or from above the bulkhead deck.

These valves are to be located in the compartment containing the open end or in a suitable position such that the compartment may be isolated in the event of damage to the piping system.

1.2.3 Where subdivision and damage stability requirements apply and where penetration of watertight divisions by pipes, ducts, trunks or other penetrations is necessary, arrangements are to be made to maintain the watertight integrity.

1.3 Plans and particulars

1.3.1 The following plans (in diagrammatic form) and particulars are to be submitted for approval. Additional plans should not be submitted unless the arrangements are of a novel or special character affecting classification:

  1. Arrangements of air pipes and closing devices for all tanks and enclosed spaces.

  2. Sounding arrangements for all tanks, enclosed spaces and cargo holds.

  3. Arrangements of level alarms fitted in tanks, cargo holds, machinery spaces, pump rooms and any other spaces.

  4. Arrangements of any cross flooding or healing tank systems.

  5. Bilge drainage arrangements for all compartments which are to include details of location, number and capacity of pumping units on bilge service.

  6. Ballast filling and drainage arrangements.

  7. Fuel oil filling, transfer, relief and spill/drainage arrangements.

  8. Tank overflow arrangements.

  9. Arrangements for flooding holds together with blanking arrangements for bilge and ballast piping systems for bulk carriers having floodable holds intended for the carriage of dangerous goods.

  10. Bilge systems for bulk carriers where the cargo holds are intended for the carriage of dangerous goods.

  11. Details verifying compliance with the sizing of air pipes required by Pt 5, Ch 11, 10.8 Size of air pipes.

  12. Arrangements of fuel oil piping in connection with oil burning installations and oil fired galleys.

  13. Arrangements of fuel oil burning units for boilers and thermal fluid heaters.

  14. Arrangement of boiler feed system.

  15. Arrangements of thermal fluid circulation systems.

  16. Arrangement of compressed air systems for main and auxiliary services.

  17. Arrangement of lubricating oil systems.

  18. Arrangements of flammable liquids used for control and heating systems

  19. Arrangements of power transmission systems for services essential for safety or for the operation of the ship on the inland waterway.

  20. Arrangements of cooling water systems for main and auxiliary services.

  21. Fuel oil tanks and lubricating and hydraulic oil tanks with a capacity of 500 litres or more, not forming part of the ship’s structure.

  22. Arrangements and dimensions of all steam pipes, with details of flanges, bolts and weld attachments, and particulars of the material of pipes, flanges, bolts and electrodes.

  23. Arrangements and details of box coolers for main and auxiliary services.
