Overview

This standard identifies the competencies you need to assist with the disconnection and removal of yacht and boat electrical/electronic equipment in preparation for activities such as repair or refit in accordance with approved procedures. This will involve disconnecting and removing equipment at component or unit level on a variety of different types of electrical/electronic equipment such as power supply and distribution equipment, lighting, domestic equipment, alarm, motor/rotating equipment, pumping equipment, entertainment equipment, instrument systems, positioning systems, autopilot systems, communication systems and radar systems.

Your responsibilities will require you to comply with organisational policy and procedures for the disconnecting and removal of the yacht or boat electrical/electronic equipment and to report any problems with the disconnection/removal activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people.  You will be expected to work with either a high level of supervision or as a member of a team. You will take personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Where team working is involved you must demonstrate a significant personal contribution during the team activities in order to satisfy the requirements of the standard and competency in all the areas required by the standard must be demonstrated.

Your underpinning knowledge will be sufficient to provide a sound basis for your work and provide an informed approach to applying disconnection and removal techniques on yacht and boat electrical/electronic equipment. You will have an understanding of the disconnection and removal methods and procedures used and their application. You will know about the electrical/electronic equipment being removed, in adequate depth to provide a sound basis for carrying out the disconnection and removal activities to the required specification.

You will understand the safety precautions required when carrying out the electrical/electronic equipment disconnection and removal activities, especially those for isolating the equipment and taking the necessary safeguards to protect yourself and others in the workplace. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace, both ashore and afloat.

  5. the precautions to be taken to prevent electrostatic discharge (ESD) damage to circuits and sensitive components (such as use of earthed wrist straps)

  6. what constitutes a hazardous voltage and how to recognise victims of electric shock

  7. how to reduce the risks of a phase to earth shock (such as insulated tools, rubber matting and isolating transformers)

  8. how to obtain the necessary job instructions required for the work being carried out

  9. the extent to which the equipment is to be dismantled for removal

  10. the different types of cabling used in the yacht or boat electrical/electronic installations and their method of disconnection (such as multi-core cables, single core-cables, steel wire armoured (SWA), mineral insulated (MI), screened cables)
  11. the different types of wiring enclosures that are used to include conduit and trunking systems and the methods of removing them
  12. the techniques used to disconnect and remove electrical/electronic equipment (such as unplugging, de-soldering, removal of screwed, clamped and crimped connections)
  13. methods of removing and replacing cables and wires in wiring enclosures without causing damage to existing cables
  14. methods of attaching identification marks/labels to removed components or cables to assist with re-assembly

  15. methods of supporting and lifting the equipment being removed

  16. the tools and equipment used in the disconnection activities including the use of soldering irons, gland disconnecting tools
  17. why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
  18. the storage requirements of removed units and assemblies which are not part of the repair/overhaul process
  19. the methods used to protect and prepare the removed equipment during transportation to the place of repair/overhaul

  20. the generation of maintenance documentation and/or reports following the disconnection and removal activity

  21. the problems that can occur during the electrical/electronic disconnection and removal activity and how they can be overcome
  22. the extent of your own authority and who you should report to when you have a problem you cannot resolve
