Carrying out condition monitoring on marine mechanical equipment

URN: SEMME3099
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 conditioning monitoring of marine mechanical plant and equipment, in accordance with approved procedures.  You will be required to select the appropriate monitoring equipment to use, based on the type of plant or equipment being monitored and the conditions you wish to check.  You will be expected to check that the equipment is in a suitable condition to use (such as undamaged, correctly calibrated, appropriate range) and to set up the equipment ready for use.  You will then use this equipment to carry out diagnostic condition monitoring (fault diagnosis or prognosis) on a range of marine equipment such as piston or turbine engines, gear boxes, stabilisers, pumps and compressors, propeller shafts (including controllable pitch propeller systems), steering and rudder arrangements, aircraft lifts, ballast arrangements, liquid oxygen equipment, weapons equipment, sewage treatment, reverse osmosis and low pressure steam plant and other specific marine equipment.

Your responsibilities will require you to comply with organisational policy and procedures for the condition monitoring activities undertaken and to report any problems with the diagnostic equipment, or monitoring activities, that you cannot personally resolve, or are outside your permitted authority, to the relevant people.  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 conditioning monitoring techniques to marine mechanical equipment.  You will understand the monitoring methods and procedures used and their application and will know about the various monitoring units and peripheral components, in adequate depth to provide a sound basis for carrying out the monitoring activities safely and correctly.

You will understand the safety precautions required when carrying out the monitoring 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. correctly set up and check-calibrate the equipment required for the monitoring being carried out
  3. carry out the monitoring activities with the minimum disruption to normal activities
  4. record and review the outcomes and take appropriate actions
  5. complete relevant documentation in line with organisational procedures

Knowledge and Understanding

You need to know and understand:

  1. the specific health and safety precautions to be applied during the monitoring procedure and their effects on others 

  2. the health and safety requirements of the area in which the monitoring activity is to take place and the responsibility they place on you

  3. 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)

  4. hazards associated with carrying out monitoring activities on marine mechanical plant and equipment (such as electrical supplies, moving machinery, process controller interface, using damaged or badly maintained tools and equipment, not following laid-down procedures) and how they can be minimised
  5. how to obtain and interpret drawings, charts, specifications, manufacturers' manuals, history/maintenance reports, symbols used on monitoring instrument documents and other documents needed in the monitoring/maintenance process
  6. how to carry out currency/issue checks of the specifications you are working with
  7. the basic principles of how the system to be monitored functions, its operating sequence, the working purpose of individual units/components and how they interact  
  8. the basic principles of condition monitoring and how it helps prevent equipment failure
  9. the different types of monitoring component or sensor (temperature, force, pressure, vibration, rotational, voltage, current), their fittings and their application
  10. the various monitoring systems and the methods that can be employed to make test measurements for the purposes of machinery protection or predictive maintenance
  11. methods of attaching monitoring components to different parts of the plant, equipment or system
  12. the importance of checking that monitoring instruments are fit for purpose, undamaged and have a suitable monitoring range and value
  13. the importance of monitoring equipment calibration and authorisation procedures
  14. the need to set up and operate condition monitoring equipment correctly
  15. care and control procedures for condition monitoring equipment
  16. the problems that can occur during the monitoring activity and how they can be overcome
  17. recording the results from conditioning monitoring and the documentation to be used
  18. control procedures for reporting results from condition monitoring 
  19. the organisational procedure to be adopted for the safe disposal of waste of all types of materials
  20. the extent of your own authority and whom you should report to if you have a problem that you cannot resolve
