Assessment tool

Version 1.0
Issue Date: April 2024

This unit involves the skills and knowledge required to operate and perform basic maintenance on a reciprocating steam engine up to 750 kW nominal propulsion power according to relevant workplace practices and codes of practice. It includes operating controls, monitoring performance and maintaining operational condition of reciprocating steam engines and steam auxiliary equipment during use.

This unit applies to engine workers working in the maritime industry as a Marine Engine Driver Steam.
