2.1 General

2.1.1 The emissions abatement plant is to be capable of operating at the maximum output power of the combustion machinery to which it is connected. Where the machinery installation is configured such that it is not intended to operate all the combustion machinery connected to the emissions abatement plant simultaneously in normal operating conditions, this will be subject to special consideration and supported by the submission required by Vol 2, Pt 12, Ch 1, 3.1 General 3.1.2. For engines, the maximum power is as stated on the Engine International Air Pollution Prevention Certificate (EIAPPC) or an equivalent certificated engine rating for vessels which are not subject to MARPOL Annex VI - Regulations for the Prevention of Air Pollution from Ships.

2.1.2 Operation and maintenance of the emissions abatement plant is not to present a hazard to the ship’s occupants or to the environment and should not impair the functioning of Mobility category or Ship Type category systems.

2.1.3 Failure of the emissions abatement plant is not to present a hazard to the ship’s occupants and should not impair the functioning of Mobility category or Ship Type category systems.

2.1.4 Where the emissions abatement plant is connected to combustion machinery providing power for Mobility or Ship Type systems, failure, or the inability to operate the emissions abatement plant, is not to prevent the combustion machinery from delivering sufficient power to those Mobility or Ship Type systems to ensure the safe operation of the ship.

2.1.5 Any discharges overboard from the emissions abatement plant are to be in accordance with the requirements of National and International regulations, as applicable.
