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.

                                 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.

                                 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.
