Elements and Performance Criteria

1. Prepare to install jet drive propulsion system
   • Job requirements are determined from workplace instructions
   • Installation procedures and information are sourced and interpreted
   • Installation options are analysed and those most appropriate to the circumstances are selected
   • Hazards associated with the work are identified and risks are managed
   • Tools, equipment and materials are selected and checked for serviceability
2. Install and commission system
   • System is checked for correct application and components are checked for damage
   • System is installed according to manufacturer specifications, workplace procedures and safety requirements, and without causing damage to components or systems
   • Installed system is tested for correct operation and required adjustments are made according to manufacturer specifications, workplace procedures and safety requirements
   • System is re-tested in normal operating conditions and final adjustments are made
3. Complete work processes
   • Final inspection is made to ensure work is to workplace expectations and vessel is presented ready for use
   • Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
   • Tools and equipment are checked and stored according to workplace procedures
   • Workplace documentation is processed according to workplace procedures
