Description
This unit involves the skills and knowledge required to perform basic engineering calculations required for the operation of marine machinery and equipment.This unit applies to people working in the maritime industry in the capacity of:Electro-Technical Officer (STCW Electro-Technical Officer Unlimited)Engineer Class 3 Near CoastalEngineer Watchkeeper (STCW Engineer Watchkeeper Unlimited). Licensing/Regulatory InformationLegislative and regulatory requirements are applicable to this unit. Regulatory requirements include STCW International Maritime Organization (IMO) model course competencies and areas of knowledge, understanding and proficiency, together with the estimated total hours required for lectures and practical exercises. Teaching staff should note that timings are suggestions only and should be adapted to suit individual groups of trainees depending on their experience, ability, equipment and staff available for training.Near Coastal Qualifications:This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as an Engineer Class 3 Near Coastal as defined in the Marine Order 505 (Certificates of competency - National Law) 2013.Blue Waters Qualifications:This unit is one of the requirements to obtain Australian Maritime Safety Authority (AMSA) certification as an Electro-Technical Officer (STCW Electro-Technical Officer Unlimited) or Engineer Watchkeeper (STCW Engineer Watchkeeper Unlimited) and to meet regulatory requirements this unit must be delivered consistent with Marine Orders and with the relevant sections of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW).
Notes
Elements and Performance Criteria
1 Apply mathematical formulae to solve 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 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 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 (CG) 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
  • 3.5 Sine rule and cosine rule for solution of triangles are proved and applied
