Description | |||
Employability Skills | |||
Learning Outcomes and Application | This unit involves the knowledge required to operate and maintain main steam propulsion plant and associated control systems on a commercial vessel.This unit applies to the work of Marine Engineering Watchkeepers on commercial vessels greater than 750 kW and forms part of the requirements for the Certificate of Competency Marine Engineer Watchkeeper 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 basic knowledge of marine steam turbines and main boilers can be demonstrated. Resources for assessment include access to: diagrams, specifications and other information required for performing basic calculations related to marine steam turbines relevant documentation including workplace procedures, regulations, codes of practice and operation manuals technical reference library with current publications on basic marine steam turbines tools, equipment and personal protective equipment currently used in industry. Performance should be demonstrated consistently over time and in a suitable range of contexts. |
