What an assessment for MARL046 must cover
28 assessable components: 2 elements (8 performance criteria), 15 performance evidence and 5 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.
Elements & performance criteria
1 Calculate fuel consumption and storage
- 1.1Information required for calculations related to fuel consumption and storage is obtained from relevant sources
- 1.2Calculations are completed to accepted working tolerances
- 1.3Results of calculations are verified
- 1.4Results of calculations are applied to managing fuel, as required
2 Complete calculations related to engine performance
- 2.1Information required for calculations related to engine performance is obtained from relevant sources
- 2.2Calculations are completed to accepted working tolerances
- 2.3Results of calculations are verified
- 2.4Results of calculations are applied to managing engine performance, as required
Performance evidence
- 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
- using calibration tables to measure quantities in tanks
- using relative density/specific gravity to convert quantity in litres and volume to mass
- 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
- converting fractions to decimals
- converting units to multiples of base units
Knowledge evidence
- 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

Questions about assessing MARL046
What does an assessment tool for MARL046 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MARL046 needs to address all 28 unit components: 2 elements with 8 performance criteria, 15 performance evidence requirements, 5 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.
How does Auditori generate an assessment tool for MARL046?
Auditori pulls the current release of MARL046 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.
Is the first assessment tool really free?
Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MARL046 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MARL046 assessment instead of generating a new one?
Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MARL046, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
