Version 1.0
Issue Date: March 2024


This unit involves the skills and knowledge required to operate 220 to 440 voltage alternating current (AC) electrical systems.

This unit applies to engine workers in the maritime industry working as a Marine Engine Driver Grade 2 Near Coastal on vessels up to 750 kW or as a Marine Engine Driver Grade 1 Near Coastal on vessels up to 1500 kW or as a Marine Engine Driver Steam.

This unit has links to legislative and certification requirements.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
