MARITIME ENGINEERING
Evaluate and enhance operating
performance of ship's machinery, plant,
and systems
level:
5
credit:
7
planned review date:
January 1998
sub-field:
Maritime
purpose:
This unit standard is for people in the maritime engineering
industry and relates to operating a ship to the desired level
of performance. It relates to the performance of the ship as
a whole and the identification of trends, rather than the
performance of individual components of the system at one
given time.
People credited with this unit standard are able to: identify
performance variations from the norm; establish the cause of
performance variation; and design and draft modification
requirements.
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.

Elements and Performance Criteria
element 1
Identify performance variations from the norm.
performance criteria
1.1
Operations to establish variance are planned and carried out in accordance
with company safety rules and regulations.
1.2
Systems and procedures for identifying the extent and nature of the variance
are selected and comply with organisational engineering practices.
Range:
1.3
variances continuous, intermittent, reduced performance,
malfunction, adverse trends which could lead to reduced
performance or malfunction.
Alterations made to quantify the limits of the variance support the maintenance
of operations.

1.4
Identification of the extent and nature of the variance is completed within
agreed time scales.
Range:
1.5
time frames are agreed with those parties who hold control of, or
accountability for, the related context of the performance.
The effect of the variance on associated plant and interfaced systems is
identified and recorded.
Range:
engine room log books, performance printouts, plant log books.
element 2
Establish the cause of performance variation.
performance criteria
2.1
Investigations are planned and carried out in accordance with company safety
rules and regulations.
2.2
Information relating to operating performance is sought, collected, and
recorded.
Range:
2.3
recording formats are defined by individual companies.
Specialist tools and equipment are used in accordance with technical
specifications and manufacturer’s instructions.
Range:
specialist equipment - measuring and recording system, testing
and monitoring system.

2.4
Sequence of diagnostic actions supports the maintenance of operations and is
agreed with the correct personnel.
Range:
2.5
Fault finding techniques follow the sequence of engineering diagnostic
procedures.
Range:
2.6
correct personnel - those parties who hold control of, or
accountability for, the related context of the performance.
measuring and recording procedures - inputs, outputs, continuity,
containment, stability.
The causes of variance are identified within an agreed time scale.
Range:
time scales are agreed with those parties who hold control of, or
accountability for, the related context of the performance.
element 3
Design and draft modification requirements.
performance criteria
3.1
Modifications are planned and carried out in accordance with company safety
rules and regulations.
3.2
Communication with parties concerning the implementation of modification
requirements is completed within a time frame which allows for continued safe
operation of a vessel.
Range:
parties - suppliers, safety authorities, manufacturers, classification
authority and flag state.

Major modifications are drawn and presented to the correct parties for required
approval.
Range:
3.4
Information on new modifications is obtained and recorded for future reference.
Range:
3.5
major modifications - structural alterations, pressure vessels, high
pressure and temperature fuel or oil line;
correct parties - those parties who hold control of, or
accountability for, the related context of the performance.
sources - marine engineer’s review, engineering publications,
other vessels, classification.
Modifications and designs conform to environmental, financial, and legislative
rules and regulations.
