Section 1 General requirements

Parent topic: Chapter 3 Waste Systems

1.1 General

1.1.1 This Chapter states the requirements for waste matter systems and arrangements installed in naval ships.

1.1.2 The requirements in this Chapter cover arrangements, equipment, and control systems necessary for effective functioning of waste matter systems on board a naval ship.

1.2 Scope

1.2.1 Waste matter systems included in this Chapter cover the following:

  1. Sewage waste

  2. Galley waste

  3. Grey water

  4. Black water

  5. Solid waste

  6. Medical, sanitary, oil contaminated and hazardous waste.

Waste materials related to naval ship military operations are outside the scope of these requirements.

1.2.2 Oily wastes from machinery and other spaces are within the scope of the ENV and POL class notations, see Vol 3, Pt 3, Ch 2 Environmental Protection and Vol 3, Pt 3, Ch 1 Pollution Prevention.

1.2.3  Sewage waste means:

  1. Drainage and other wastes from any form of toilets, urinals and WC scuppers.

  2. Drainage from medical premises (dispensary, sick, etc.) via wash basins, wash tubs and scuppers located in such spaces.

  3. Other wastes waters when mixed with drainages defined in (a) and (b).

1.2.4  Galley waste means drainage from galleys that may be contaminated with food or other organic waste that may give rise to smell.

1.2.5  Grey water means drainage from baths, showers, sinks and laundry systems.

1.2.6  Black water means drainage from sewage systems and chemical wastes that could constitute a recognised health and safety risk to persons on board.

1.2.7 For the purposes of treatment and disposal: solid waste means food waste, plastics, medical waste, sanitary waste, oily rags and other dry waste such as paper, glass, metal, rags (non-oily) and packing materials. Contaminated CBRN protective wear are not within the scope of this definition.

1.3 Documentation required for design review

1.3.1 Three copies of the plans and information stated in Vol 2, Pt 11, Ch 3, 1.3 Documentation required for design review 1.3.2 is to be submitted to LR as applicable.

1.3.2  System Design Description A System Design Description of the waste systems, see Vol 2, Pt 1, Ch 3, 3.5 System design description.

1.3.3  Waste treatment and disposal plan. A plan detailing the intended handling and treatment of solid waste is to be provided on board the ship. The plan is to detail the waste treatment procedures for all categories of solid waste with respect to the following criteria:

  1. Estimate of total production of each waste type per crew member for a specified period for each specific ship's voyages/missions.

  2. Processing facilities for solid waste matters, access and maintainability.

  3. Waste retention/storage facilities, including size and location on board the ship, access and separation.

  4. Overboard disposal of waste and permissions.

  5. Disposal of waste ashore and handling facilities.

  6. Treatment and handling of specialist waste, e.g. medical and oil contaminated waste.

  7. Hygiene.

  8. Waste segregation arrangements.

1.3.4  Systems. Plans in diagrammatic form showing piping arrangements, control systems and safeguards and electrical systems covered by this Chapter. The major component parts, pipe sizes, system flow rates and pressures together with capacities of pumps and plants and tanks are to be included. Any Standards or Design Guidance used for system design are to be stated.

1.3.5  Compartments. Plans showing the general arrangement of compartments, together with a description of the equipment and arrangements installed for handling, treatment, storage and disposal of waste and the electrical power supply systems. The plans are to indicate segregation and access arrangements for compartments and associated control rooms/stations.

1.3.6  Testing and trials procedures. A schedule of testing and trials to demonstrate that systems are capable of operating as described in Vol 2, Pt 11, Ch 3, 3 System arrangements.

1.3.7  Operating Manuals. Operating Manuals are to be provided on board and submitted for information where requested by LR. The manuals are to include the following information:

  1. Particulars and a description of the systems.

  2. Operating instructions for the equipment and systems.

  3. Arrangements for the disposal of oily wastes from galleys.
