Business Sectors (Suites): Marine Engineering Suite 3
Developed by: Enginuity
Approved on: 28 Feb 2019

Overview

This standard identifies the competences you need to reassemble and refit marine mechanical equipment following the completion of overhauling activities. This will involve reassembling and refitting equipment at component or unit level on a variety of different types of marine mechanical assemblies and sub-assemblies, such as propulsion and transmission, fluid power, steering and control, lifting equipment, refrigeration and air conditioning, fire main equipment and pantry and galley equipment.

Your responsibilities will require you to comply with organisational policy and procedures for the reassembling and refitting of the marine mechanical equipment and to report any problems with the activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used in the activities are removed from the work area on completion of the activities and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with a minimum of supervision, taking personal responsibility for your actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying reassembling and refitting techniques on marine mechanical equipment. You will understand the reassembling and refitting methods and procedures used and their application. You will know about the mechanical equipment being refitted, in adequate depth to provide a sound basis for carrying out the reassembling and refitting activities to the required specification.

You will understand the safety precautions required when carrying out the reassembling and refitting activities, especially those for connecting the equipment. You will be required to demonstrate safe working practices throughout and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace, both ashore and afloat.

Performance criteria

You must be able to:

  1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines

  2. follow all relevant drawings and specifications for the activity being carried out

  3. use the correct tools and equipment for the reassembling and refitting operations and check that they are in a safe and usable condition
  4. reassemble, refit, position and secure the equipment and components in accordance with the specification
  5. ensure that all necessary connections to the equipment are complete
  6. deal promptly and effectively with problems within your control and report those that cannot be solved
  7. check that the installation is complete and that all components are free from damage
  8. complete relevant documentation in line with
    organisational procedu    res
