MARITIME ENGINEERING
Diagnose unacceptable or unscheduled
variation in marine electrical systems
Elements and Performance Criteria
element 1
Identify marine electrical system variations from the norm.
performance criteria
1.1
Operations to identify variance are planned and carried out in accordance with
established safety rules and regulations.
1.2
Systems and procedures selected for identifying the extent and nature of the
variance comply with organisational engineering practices.
1.3
Alterations made to quantify the limits of the variance support the maintenance
of the ship’s operations.
Range:
1.4
Identification of the extent and nature of the variance is completed within time
scales consistent with instructions and operational demands.
Range:
1.5
alteration - immediate shut down or change over, immediate
replacement or repair, deferred replacement or repair, adjustment
of presets, routine servicing, adjustment of operational controls.
instructions - Chief Engineer’s instructions.
The effect of the variance on associated plant and interfaced systems is
identified and recorded for future reference.

element 2
Establish the cause of variation in marine electrical systems.
performance criteria
2.1
Investigation is planned and carried out in accordance with established safety
rules and regulations.
2.2
Procedures for the isolation, dismantling, and reassembly of plant and
equipment meet the needs of the planned investigation.
Range:
2.3
procedures - as detailed in technical instructions and applying
electrical and electronic engineering diagnostic procedures.
Specialist tools and equipment are used in accordance with technical and
manufacturer’s instructions.
Range:
specialist equipment measuring and recording, system
testing and monitoring, environment testing and monitoring.
2.4
Sequence of diagnostic actions supports the maintenance of the ship’s
operations and is agreed with operational and engineering supervisory
personnel.
2.5
Fault finding techniques are undertaken in accordance with engineering
diagnostic procedures.
Range:
2.6
measuring and recording procedures - inputs, outputs, continuity,
containment, stability.
The cause of the identified variance is identified, recorded, and communicated
to the supervising engineer within stated time scales.
Range:
time scales are set by the supervising engineer;
recording - engine room log book, equipment log book.
