6.1 Minimization of hazardous substances used in the construction of new ships and their equipment

  6.1.1 Some of the problems associated with ship recycling might be addressed at the design and construction stage, not only in relation to the ships themselves but also in respect of ships' equipment. The first step is to identify any potentially hazardous materials which might be incorporated, as a matter of routine, in the structure of ships and their equipment (see Section 4) and, where practicable, consider using less hazardous alternatives.

  6.1.2 The second step is to minimize hazardous materials generated during the operating life of a ship and at the end of a ship's life. Shipbuilders should already be aware of the need to minimize emissions and hazardous wastes to a level as low as reasonably achievable.

  6.1.3 The initial stages might include an evaluation of:

  • .1 the type, amount and potential hazard of materials utilized and their location on board a ship;

  • .2 the activities expected during the operation of the ship and any potentially hazardous wastes which might be generated; and

  • .3 the feasibility of addressing the potential for hazardous waste generation by considering:

    • .1 product reformulation - installing components utilizing less potentially hazardous materials;

    • .2 cleaner production technologies - which generate less wastes;

    • .3 process modification - to generate less waste;

    • .4 input substitution - utilizing less potentially hazardous consumables or those which generate less waste; and

    • .5 on-site, closed-loop recycling - systems that recycle wastes on board the ship.

  6.1.4 Ship designers and shipbuilders are encouraged to take due account of the ship's ultimate disposal when designing and constructing a ship, by:

  • .1 using materials which can be recycled safely and in an environmentally sound manner; and

  • .2 minimizing the use of materials known to be potentially hazardous to health and the environment.

  6.1.5 In general terms, if opportunities exist, ship or equipment designers should recommend designs to ship operators that minimize or prevent waste at source and at the end of the operating life of the ship. Similarly, shipowners and operators should ask for such design considerations for new buildings and retrofits.

  6.1.6 Administrations and the competent authorities of ship building States are encouraged to advise shipbuilders to limit the use of hazardous materials in the construction of ships.

  6.1.7 The competent authorities of ship building States have a role in encouraging research into the use of less potentially hazardous materials in the construction of ships and promoting the use of techniques which, without compromising safety or operational efficiency, contribute towards the facilitation of the recycling operation.

  6.1.8 Substances prohibited or restricted by international conventions such as the Stockholm Convention on Persistent Organic Pollutants (POPs), the Montreal Protocol on Substances that Deplete the Ozone Layer, and the International Convention on the Control of Harmful Anti-fouling Systems on Ships, should not be used in the construction, refit and repair of ships.
