Employability Skills | |||
Learning Outcomes and Application | This unit involves the skills and knowledge required to apply advanced principles of marine mechanics and to perform associated calculations needed to operate and maintain marine machinery.This unit applies to the work of a Marine Engineer Class 1 on commercial vessels of unlimited propulsion power and forms part of the requirements for the Certificate of Competency Marine Engineer Class 1 issued by the Australian Maritime Safety Authority (AMSA).No licensing, legislative or certification requirements apply to this unit at the time of publication. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements. Assessment must satisfy the National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) standards. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Assessment must occur in workplace operational situations or where these are not available, in simulated workplace operational situations or an industry-approved marine operations site that replicates workplace conditions where advanced principles of marine mechanics can be applied Resources for assessment include access to: applicable documentation including workplace procedures, regulations, codes of practice and operation manuals diagrams, specifications and other information required for performing advance calculations related to marine mechanics relevant regulatory and equipment documentation that impacts on work activities technical reference library with current publications on advanced marine mechanics tools, equipment, materials and personal protective equipment currently used in industry. Performance should be demonstrated consistently over time and in a suitable range of contexts. |
