Outline size, shape and structural components of vesselsĬorrect terms to describe size and shape of vessels are usedĬorrect terms to describe structural components of vessels are usedĬorrect terms to describe size or cargo carrying capacity of vessels are used Performance criteria describe the performance needed to demonstrate achievement of the element. Elements and Performance CriteriaĮlements describe the essential outcomes. No licensing, legislative or certification requirements apply to this unit at the time of publication. This unit applies to the work of a Marine Engineer Class 2 on commercial vessels greater than 3000 kW and forms part of the requirements for the Certificate of Competency Marine Engineer Class 2 issued by the Australian Maritime Safety Authority (AMSA). This unit involves the skills and knowledge required to explain the basic principles of ship construction.
