Carrying out planned maintenance activities on marine mechanical equipment

URN: SEMME3098
Business Sectors (Suites): Marine Engineering Suite 3
Developed by: Enginuity
Approved on: 28 Feb 2019

Overview

This standard identifies the competences you need to carry out planned maintenance activities on marine mechanical equipment, in accordance with approved procedures.  You will be required to carry out maintenance activities on a range of marine mechanical equipment, such as gear boxes, stabilisers, pumps, propeller shafts (including controllable pitch propeller systems), steering and rudder arrangements, aircraft lifts, ballast arrangements, engines, liquid oxygen equipment, weapons equipment, sewage treatment, reverse osmosis and low pressure steam plant and other specific marine equipment, in order to minimise down time and ensure that they perform at optimum level and function to specification. 

Your responsibilities will require you to comply with organisational policy and procedures for the maintenance activities undertaken and to report any problems with the maintenance process, tools or equipment 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 maintenance activities are removed from the work area on completion of the work and 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 own 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 planned maintenance procedures to marine mechanical equipment.  You will understand the process of developing planned maintenance and its application, in adequate depth to provide a sound basis for carrying out the activities to the required specification.  In addition, you will also be expected to report where the outcome identifies the need for further investigation or maintenance work.

You will understand the safety precautions required when carrying out the maintenance activities, especially those for isolating 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 the relevant maintenance schedules to carry out the required work
  3. carry out the maintenance activities within the limits of your personal authority
  4. carry out the maintenance activities in the specified sequence and in an agreed time scale
  5. report any instances where the maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
  6. complete relevant documentation in line with organisational procedures, and pass them on to the appropriate person
  7. dispose of waste materials in accordance with safe working practices and approved procedures

Knowledge and Understanding

You need to know and understand:

  1. the health and safety requirements of the area in which the maintenance activity is to take place and the responsibility they place on you
  2. the isolation procedures or permit-to-work procedure that applies to the equipment being maintained
  3. the specific health and safety precautions to be applied during the planned maintenance procedure and their effects on others
  4. how to recognise and deal with emergencies and the procedures to be followed (such as methods of safely evacuating and closing down of compartments in the case of fire or other major incident, first aid, fire fighting and resuscitation of personnel)

  5. the importance of wearing protective clothing and other appropriate safety equipment (PPE) during maintenance activities

  6. hazards associated with carrying out planned maintenance activities on marine mechanical equipment (such as handling oils/greases, stored pressure/force, misuse of tools) and how they can be minimised

  7. where to obtain and how to interpret drawings, specifications, manufacturers' manuals, maintenance schedules and other documents identifying functional parameters
  8. the various planned maintenance schedules that are generally used (such as condition based maintenance, scheduled maintenance and total productive maintenance (TPM))
  9. the procedure for obtaining the consumables to be used during the planned maintenance activity
  10. how to make sensory checks by sight, sound, smell, touch
  11. the appropriate testing procedures to be adopted during the maintenance activity
  12. how to make adjustments to components/assemblies to ensure that they function to specification
  13. the functionality of various mechanical components and their interrelationship with other components and assemblies
  14. how to compile planned maintenance records/logs/reports which satisfy company policy and procedures
  15. the equipment operating and control procedures and how to apply them in order to carry out planned maintenance
  16. the problems that can occur whilst carrying out the planned maintenance activities and how they can be avoided
  17. the organisational procedure to be adopted for the safe disposal of waste of all types of materials
  18. the extent of your own authority and whom you should report to if you have problems that you cannot resolve
