Critical equipment and systems
should
include as a minimum, but not be limited to fire-detection and fire-
fighting systems, vessel evacuation systems; crankcase oil-mist detectors, steering gear, emergency
generator, main-engine shutdown alarms, propulsion and positioning systems, and ventilation and air
conditioning systems.
Where redundancy is provided for operational reasons, equipment
should not
be considered as non-critical.
Procedures are in place to identify mechanical, electrical and other items of equipment, including specialist
equipment used in the vessel’s operations that, in the event of a failure, may result in a hazardous situation.

Identification of Critical Equipment
shall
be made by FMEA (Failure Mode Effect Analysis) and Risk Analysis
of vessel specific systems and components.
Criticality may also be linked to contractual agreements with clients and charter for the intended voyage or
service and need to be identified at the Pre-Contract phase.
Critical Equipment Analysis
shall
be delivered by Life Cycle Department.
The
Technical
S
u
p
erintendent
responsible for the vessel
shall
ensure that a controlled electronic copy of
the Critical Equipment Analysis is sent to the vessel.
Ve
ss
el Ma
s
ter
shall
ensure Critical Equipment Analysis is communicated to each Officer on board and
properly archived to be made available if required during an audit.
Critical equipments, maintenance activities and spare parts are identified in the vessel CMMS.
Critical spares and spare parts are those that each vessel
shall
have on board at any time in a predefined
quantity.
Critical maintenance is maintenance that cannot be postponed or delayed.
In addition to the specific measures to address regular operational maintenance and tests within the CMMS,
technical inspections
shall
include thorough operational testing of all such systems and equipment,
particularly of those stand-by arrangements and equipment or technical systems that are not in continuous
use.
The
Technical
S
u
p
erintendent
responsible for the vessel
shall
ensure that adequate follow-up is completed
for any defect or other areas of concern reported through the normal channels or during the course of a
technical inspection.
All technical defects
shall
be reported in as per details provided in section § 4.4 and investigated to
determine the root causes such that proper action is taken to correct them and make any suitable
recommendations to the
Technical Manager
to prevent any re-occurrence or similar defects.
