Employability Skills | |||
Learning Outcomes and Application | This unit involves the skills and knowledge required to operate and maintain marine auxiliary boilers on a commercial vessel. This includes analysing the responsibilities of an Engineer Class 2 in relation to auxiliary boiler and steam plant of a vessel, the design of marine auxiliary boilers, the operation of thermal fluid heating plants, the layout of marine stem systems and components, and procedures for inspecting marine auxiliary boilers and associated plant.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).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 intermediate knowledge of marine auxiliary boilers can be demonstrated. Resources for assessment include access to: applicable documentation including workplace procedures, regulations, codes of practice and operation manuals diagrams, specifications and other information related to marine auxiliary boilers technical reference library with current publications on basic marine auxiliary boilers tools, equipment, materials and personal protective equipment currently used in industry required to operate and maintain marine auxiliary boilers. Performance should be demonstrated consistently over time and in a suitable range of contexts. |
