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.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, the required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include:

accurately calculating voyage fuel requirements

performing accurate and reliable calculations.

Context of and specific resources for assessment

Performance is demonstrated consistently over time and in a suitable range of contexts.

Resources for assessment include access to:

industry-approved marine operations site where carrying out engineering calculations can be conducted

tools, equipment and personal protective equipment currently used in industry

relevant regulatory and equipment documentation that impacts on work activities

range of relevant exercises, case studies and/or other simulated practical and knowledge assessments

appropriate range of relevant operational situations in the workplace.

In both real and simulated environments, access is required to:

relevant and appropriate materials and equipment

applicable documentation including workplace procedures, regulations, codes of practice and operation manuals.

Method of assessment

Practical assessment must occur in an:

appropriately simulated workplace environment and/or

appropriate range of situations in the workplace.

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit:

direct observation of the candidate carrying out engineering calculations

direct observation of the candidate applying relevant WHS/OHS requirements and work practices.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.

In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.

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

Submission Requirements

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.

Required Skills:

Calculate:

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 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

Convert:

fractions to decimals

units to multiples of base units

Use calibration tables to measure quantities in tanks

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

Required Knowledge:

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 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

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

Calculations related to fuel consumption and storage must include:

Calculations involving:

specific fuel consumption

volume and capacity of regular shaped tanks

pumping capacities for tank filling and emptying

consumption of fuel and lubricating oil

hourly fuel consumption

Hourly fuel consumption

Requirements for replenishing lubricating oil in oil tank

Using calibration tables to measure quantities in tanks

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

Calculations related to engine performance must include:

Calculations involving:

theoretical steaming times

distances covered

specific power, speed and range

theoretical steaming times

mechanical advantage, load, effort moments

stress, strain and safe working load

Remaining steaming times

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.
