Overview

This standard identifies the competencies you need to assist with the disconnection and removal of yacht and boat mechanical equipment in preparation for activities such as repair or refit in accordance with approved procedures. The activities will involve disconnecting and removing equipment at component or unit level on a variety of different types of yacht or boat mechanical assemblies and sub-assemblies, such as outboard engines, direct current electric motors or steam engines; gear boxes; stabilisers; pumps (such as sea water, fresh water and jet); propeller shafts; steering and rudder arrangements; lifting equipment (such as anchor windlass, winches and hoists); domestic equipment and other specific yacht or boat mechanical/ancillary equipment.

Your responsibilities will require you to comply with organisational policy and procedures for the disconnecting and removal of the yacht or boat mechanical 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 mechanical equipment. You will have an understanding of the disconnection and removal methods and procedures used and their application. You will know about the mechanical 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 disconnection and removal of the yacht or boat mechanical equipment, especially those for isolating and/or depressurising 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, both ashore and afloat.

  3. ensure that any stored energy or substances are released safely and correctly
  4. make all isolations and disconnections to the equipment in line with approved procedures
  5. assist in the disconnection and removal of equipment to the agreed level using correct tools and techniques
  6. store equipment for re-use in approved locations
  7. dispose of unwanted components and substances in accordance with approved procedures
  8. deal promptly and effectively with problems within your control and report those that cannot be solved

  4. how to recognise and deal with emergencies and the procedures to be followed (such as methods of safely evacuating and closing down compartments in the case of fire or other major incident)
  5. the protective equipment that you need to use for both personal protection (PPE) and protection of the equipment or system
  6. how to obtain the necessary job instructions required for the work being carried out
  7. the basic operating principles of the marine mechanical equipment being removed
  8. the components/units to be removed and their function within the particular marine mechanical equipment

  10. the various mechanical fasteners that will be removed and their method of release, including threaded fasteners, special securing and locking devices
  11. the importance of using the specified release devices for the particular items being removed
  12. why securing devices need to be correctly unlocked and labelled and the different unlocking methods that are used
  13. what methods may be used to assist in the release of equipment and components where difficulty in releasing items is experienced
  14. procedures for ensuring you have the correct type of tools and equipment for the activities
  15. the techniques used to secure loose items without damage, once equipment has been removed
  16. methods of lifting, handling and supporting the components/equipment during the removal activities
  17. the removal of seals, sealant and adhesives and the precautions that need to be taken
