MARL061 — Perform basic marine engineering calculations

1 Apply mathematical formulae to solve engineering problems

• 1.1Proportions, variation, percentages and averages are calculated, and method of unity is applied
• 1.2Problems involving the manipulation of indices are solved
• 1.3Written descriptions of actual or hypothetical engineering problems are expressed in mathematical terms
• 1.4Algebraic formulae and equations are manipulated to change subjects, as and when required
• 1.5Index problems are converted to logarithmic problems, and vice versa, according to the Law of Logarithms
• 1.6Calculator is used to resolve engineering problems

2 Calculate areas, volumes and masses of regular and irregular figures

• 2.1Problems related to areas and volumes of regular geometric figures are solved using standard formulae
• 2.2Problems relating to surface areas and volumes of circular figures are solved
• 2.3Centres of gravity (CG) and centroids of area are found for both line figures and areas
• 2.4Concept of density is applied to calculate masses

3 Apply trigonometry to solve problems relating to angular measurement and the resolution of vectors

• 3.1Basic trigonometric ratios of sine, cosine and tangent, together with their reciprocals are explained with respect to the sides of a right-angled triangle
• 3.2Pythagoras’ Theorem is proved
• 3.3Problems associated with single angle trigonometric identities, including those derived from the application of Pythagoras’ Theorem to the basic sin, cos and tan identities, are solved
• 3.4Derivation of multiple, double and half angle trigonometric identities are shown and used to simplify complicated trigonometric expressions and identities
• 3.5Sine rule and cosine rule for solution of triangles are proved and applied

What does an assessment tool for MARL061 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MARL061 needs to address all 33 unit components: 3 elements with 15 performance criteria, 10 performance evidence requirements, 8 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 MARL061?

Auditori pulls the current release of MARL061 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 MARL061 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MARL061 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 MARL061, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
