Overview

This standard identifies the competences you need to set to work and test marine propulsion systems, such as alternating and direct current motors, steam turbines, gas turbines, two-stroke and four-stroke turbo blown, mechanically blown, naturally aspirated internal combustion engines, in accordance with approved procedures.  You will be required to use appropriate drawings, specifications and test documentation to set up and test the various types of equipment.  You will be expected to use the specified/appropriate techniques to carry out formal setting to work and testing, which will include harbour and sea trial activities, over a range of operational parameters, to establish that the machinery on test is functioning at optimal level and to specification.

Your responsibilities will require you to comply with organisational policy and procedures for the setting-up and testing activities undertaken and to report any problems with these activities, or with the tools and equipment used 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 own actions and for the quality and accuracy of the work that you carry out. **     

Your underpinning knowledge will provide a sound understanding of your work and will provide an informed approach to applying appropriate setting-up and testing procedures to marine propulsion systems.  You will understand the equipment being worked on, any test equipment to be used and the various testing procedures, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the equipment functions to the required specification.  In addition, you will be expected to review the outcomes of the tests, to compare the results with appropriate standards, to determine the action required and to record and report the results in the appropriate format.  

You will understand the safety precautions required when carrying out the setting to work and testing of marine propulsion systems, especially those relating to the risk of fire and for taking the necessary safeguards to protect yourself and others against injury.  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 in harbour and at sea.
