MARL001
Carry out engineering calculations


Application

This unit involves the skills and knowledge required to carry out calculations related to fuel consumption, fuel storage and engine performance that conform to accepted engineering tolerances.

This unit applies to engine workers in the maritime industry working as a Marine Engine Driver Grade 1 Near Coastal on vessels up to 1500 kW.

This unit has links to legislative and certification requirements.

distances covered

hourly fuel consumption

mechanical advantage, load, effort moments

pumping capacities for tank filling and emptying

remaining steaming times

requirements for replenishing lubricating oil in oil tank

specific fuel consumption, power, speed and range

stress, strain and safe working load

tank capacities and pumping capacities for tank filling and emptying

theoretical steaming times

velocity ratio and efficiency of simple machines

volume and capacity of regular shaped tanks

converting:

fractions to decimals

units to multiples of base units

performing accurate and reliable calculations

using calibration tables to measure quantities in tanks

using relative density/specific gravity to convert quantity in litres and volume.


Evidence of Knowledge

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

area and circumference of a circle

calibration tables

common SI units such as kilogram, tonne, Newton, Newton metre, Pascal, joule, watt and metre

relationship between theoretical vessel speed, propeller pitch and revolutions per minute (RPM)

terminology of:

simple levers

material technology

volumes of regular shaped tanks

work health and safety (WHS)/occupational health and safety (OHS) requirements and work practices.


Assessment Conditions

Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.

Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that reflect workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

tools, equipment, machinery, materials and personal protective equipment currently used in industry

applicable documentation such as legislation, regulations, codes of practice, workplace procedures and operational manuals

range of relevant exercises, case studies and/or simulations.


Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.


Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Calculations related to fuel consumption and storage must include:
