- Candidates who have completed AEC 1 and want to continue their engineering pathway
- Deck crew moving towards a dual deck/engineer role
- Junior or assistant engineers looking to strengthen practical engineering knowledge
- Crew working on yachts and other small commercial vessels who need broader engineering competence and better fault-finding skills
What you will learn (key outcomes)
- Refrigeration systems: understand the refrigeration cycle, component functions and common system faults
- Engineering legislation and records: develop awareness of MARPOL requirements, safe working practices and engineering documentation
- Maintenance systems: understand planned maintenance, condition monitoring and trend-based checks
- Safe systems of work: apply risk assessment, permit-to-work procedures and enclosed-space safety awareness
- Lifting and slinging: understand safe lifting techniques, inspection requirements and practical movement of equipment
