Diagnose unacceptable or unscheduled
variation in marine telecommunication
and navigational systems
level:
4
credit:
12
planned review date:
January 1998
sub-field:
Maritime

This unit standard is for people in the maritime engineering
industry. People credited with this unit standard are able to
identify marine telecommunication and navigational system
variation against the norm, and establish the cause of
variation in marine telecommunication and navigational
systems.
entry information:
Open.
accreditation option:
Evaluation of documentation and visit by NZQA and industry.
moderation option:
A centrally established and directed moderation system has
been established by Maritime Qualifications New Zealand
Inc.
special notes:

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
agreed time scales.
Range:
1.5
alterations - immediate shut down or change over, immediate
replacement or repair, deferred replacement or repair, adjustment
of presets, routine servicing, adjustment of operational controls.
agreed between engineering supervisor, trainee, and operational
supervising personnel.
The effect of the variation on associated plant and interface systems is
identified and recorded for future reference.
element 2
Establish the cause of variation in marine telecommunication and navigational systems.
performance criteria
2.1
Investigations are planned and carried out in accordance with established
safety rules and regulations.
2.2
Isolation, dismantling, and reassembly of plant and equipment meet the needs
of the planned investigation.
Range:
procedures - as described in technical instructions and applying
electronic engineering diagnostic procedures.

2.3
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 follow the sequence of electrical and electronic
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.

Please Note:
Providers must be accredited by the Qualifications Authority
before they can offer programmes of education and training
assessed against unit standards.
Accredited providers assessing against unit standards must
engage with the moderation system that applies to those unit
standards. [Please refer to relevant Plan ref: 0054].
