Description
Employability Skills
Learning Outcomes and 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.It includes calculating fuel consumption and storage and completing calculations related to engine performance.This unit applies to people working in the maritime industry in the capacity of:Chief Engineer on vessels with inboard engines less than 1500 kW within the exclusive economic zone (EEZ)Second Engineer on vessels with inboard engines less than 3000 kW within the EEZChief or Second Engineer on vessels with outboard engines with unlimited propulsion power within the EEZassistant under the direct supervision of the chief engineerworker in the engine room of a vessel less than 80 metres in length with propulsion power less than 3000 kW. Licensing/Regulatory InformationLegislative and regulatory requirements are applicable to this unit. This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as a Marine Engine Driver Grade 1 Near Coastal, as defined in the National Standard for Commercial Vessels (NSCV) Part D.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.

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.

Practical assessment must occur in a workplace, or realistic simulated workplace, under the normal range of workplace conditions.

Simulations and scenarios may be used where situations cannot be provided in the workplace or may occur only rarely, in particular for situations relating to emergency procedures and adverse weather conditions where assessment would be unsafe, impractical or may lead to environmental damage.

Resources for assessment must include access to:

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

tools, equipment, machinery, materials and personal protective equipment (PPE) currently used in industry.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Submission Requirements

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
