Unit of competency details

Unit descriptor 

This unit of competency involves routinely maintaining, restoring and repairing mechanical plant onboard a vessel according to maintenance plans and instructions or as a result of an unacceptable or unscheduled variation. This unit also covers actions required to maintain a vessel in survey.

Licensing, legislative, regulatory or certification requirements may apply to this unit. Therefore it will be necessary to check with the relevant state or territory regulators for current licensing, legislative or regulatory requirements before undertaking this unit.

Application of the unit 

This unit has application to aquaculture, fishing operations and fisheries compliance where use is made of small vessels and a maritime regulatory certification is not required. For advice on certifications refer to the current TDM07 Maritime Training Package.

The unit of competency involves the maintenance of marine mechanical plant and systems, including auxiliary machinery, propulsion plant and service systems, such as LPG and fire hose, including associated pipework and fittings.

All enterprise or workplace procedures and activities are carried out according to relevant government regulations , licensing and other compliance requirements , including occupational health and safety  (OHS ) guidelines  and ecologically sustainable development  (ESD ) principles .

Equipment operation, maintenance, repairs and calibrations are undertaken in a safe manner that conforms to manufacturer instructions. Appropriate personal protective equipment  (PPE ) is selected, checked, used and maintained.
