1.1.1 The requirements of this Chapter apply to equipment fitted to combustion
machinery in order to reduce emissions produced by the combustion of fuel. Such
equipment is hereinafter referred to as emissions abatement plant. These requirements
are intended to ensure that the emissions abatement plant is safe to operate and
maintain and, additionally, where the combustion machinery provides power for Mobility
and/or Ship Type systems, that failure of the emissions abatement plant does not result
in an unacceptable loss or degradation of those systems. These requirements do not
provide for the reliability or redundancy necessary to ensure continued operation of the
emissions abatement plant, and thereby compliance with relevant emissions requirements,
following failure of any equipment associated with the emissions abatement plant.
