Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Required Skills and 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 on at least one occasion and include:

calculating:

area and circumference of a circle

consumption of fuel and lubricating oil for a particular voyage, using quantity in litres and mass in tonnes and specified regular shaped tanks

distances covered

hourly fuel and lubricating oil consumption

mechanical advantage, load, force and moments

remaining steaming times and engine performance

specific fuel consumption, power, speed and range

stress, strain and safe working load (SWL)

tank capacities and pumping capacities for tank filling and emptying

velocity ratio and efficiency of simple machines

volume and capacity of regular shaped tanks

calculations fuel consumption and storage:

using calibration tables to measure quantities in tanks

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

converting:

fractions to decimals

units to multiples of base units.

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 International System of Units (SI), such as kilogram, tonne, Newton, Newton metre, Pascal, joule, watt and metre

relationship between theoretical vessel speed, propeller pitch and revolutions per minute (r.p.m.)

terminology of:

material technology

simple levers

volumes of regular shaped tanks

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

Range Statement

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