Description
This unit involves the skills and knowledge required to perform basic marine engineering calculations required for the operation of marine machinery and equipment.This unit applies to people working in the maritime industry as a Marine Engineering Watchkeeper on commercial vessels greater than 750 kW or as an Engineer Class 3 Near Coastal.This unit has links to legislative and certification requirements.
Notes
Elements and Performance Criteria
1 Apply mathematical formulae to solve marine engineering problems
  • 1.1 Proportions, variation, percentages and averages are calculated, and method of unity is applied
  • 1.2 Problems involving the manipulation of indices are solved
  • 1.3 Written descriptions of actual or hypothetical marine engineering problems are expressed in mathematical terms
  • 1.4 Algebraic formulae and equations are manipulated to change subjects, as and when required
  • 1.5 Index problems are converted to logarithmic problems, and vice versa, according to the Law of Logarithms
  • 1.6 Calculator is used to resolve marine engineering problems
2 Calculate areas, volumes and masses of regular and irregular figures
  • 2.1 Problems related to areas and volumes of regular geometric figures are solved using standard formulae
  • 2.2 Problems relating to surface areas and volumes of circular figures are solved
  • 2.3 Centres of gravity and centroids of area are found for both line figures and areas
  • 2.4 Concept of density is applied to calculate masses
3 Apply trigonometry to solve problems relating to angular measurement and the resolution of vectors
  • 3.1 Basic trigonometric ratios of sine, cosine and tangent, together with their reciprocals are explained with respect to the sides of a right-angled triangle
  • 3.2 Pythagoras’ Theorem is proved
  • 3.3 Problems 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
  • 3.4 Derivation of multiple, double and half angle trigonometric identities are shown and used to simplify complicated trigonometric expressions and identities
