Version 1.0 Issue Date: March 2024
This unit applies to people working in the maritime industry as a marine surveyor assistant and forms part of requirements for the Certificate IV in Domestic Commercial Vessel Survey.
This unit involves the skills and knowledge required to assist in the survey of operational systems. It covers identifying the principal characteristics of vessel propulsion, steering gear system, deck machinery, pumping systems, power generation, refrigeration plant and navigational systems that require periodic surveys for regulatory requirements.

Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.
Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate.
