Setting to work, testing and trialling marine navigational equipment and systems
Overview
This standard identifies the competencies you need to set to work, test and trial marine navigational equipment and systems, in accordance with approved procedures. You will be required to use appropriate drawings, specifications and test documentation to set up and test the various items of equipment. You will be expected to use the specified/appropriate techniques to carry out the setting-up and testing procedures in the correct sequence, in order to integrate the various elements into the navigation system. The process will include fault identification, diagnosis and if appropriate, the adjustments, corrections and rectification of the faults.
The equipment to be set up and tested will include distance measuring equipment (DME), very high frequency omni-directional range (VOR), auto direction finder (ADF), global positioning system (GPS), Doppler, long range navigation (LORAN), homing, inertial navigation system, navigational radar, electronic chart plotting systems, echo sounding systems, retransmission systems and gyrocompasses.
Your responsibilities will require you to comply with organisational policy and procedures for the navigational equipment setting-up and testing activities undertaken and to report any problems with the activities, components or equipment 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, for the quality and accuracy of the work that you carry out and for the safe working practice with due regard to radiation hazard control.
Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying setting-up and testing techniques and procedures to marine navigational systems. You will understand the navigational systems being set to work and tested and their application and will know about the testing techniques, test equipment and methods, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the system functions to the required specification.
You will understand the safety precautions required when carrying out the setting-up and testing operations, in particular those relating to radiation hazard control. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
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 setting up and operating specifications for the products or assets being configured 3. follow the defined procedures and set up the equipment correctly ensuring that all operating parameters are achieved 4. set to work, test and trial marine navigational equipment and systems using appropriate methods and techniques 5. deal promptly and effectively with problems within your control and report those that cannot be solved 6. check that the configuration is complete and that the equipment operates to specification, using appropriate methods and techniques 7. complete relevant documentation in line with organisational procedures |
Knowledge and Understanding
You need to know and understand:

- the health and safety requirements of the work area where you are carrying out the activities and the responsibility they place on you
- the safety procedures that must be carried out before work is started on setting up the marine navigational equipment
- 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)
- the protective equipment that you need to use for both personal protection of yourself and others (PPE) and protection of the system from mutual interference
- the hazards associated with setting to work, testing and trialling marine navigational systems and with the tools and test equipment that is used, and how they can be minimised
- the precautions to be taken to prevent electrostatic discharge (ESD) damage to circuits and sensitive components (such as use of earthed wrist straps)
- what constitutes a hazardous voltage and how to recognise victims of electric shock
- how to reduce the risks of a phase to earth shock (such as insulated tools, rubber matting and isolating transformers)
- how to obtain and interpret drawings, standards, quality control procedures and test specifications used in the setting to work process (including, for example, BS and ISO schematics, symbols and terminology)
- how to carry out currency/issue checks of the specifications you are working with
- the correct operating procedures of the navigational system being set to work and tested
- the components to be set to work and their function within the particular navigational systems
- the adjustments/corrections/tuning required to bring the equipment/system to operational standard through full range parameters
- the quality control procedures to be followed during the setting-to-work and testing operations
why electrical bonding is critical and why it must be both mechanically and electrically secure
types of test equipment to be used and their selection for particular types of tests
- how to calibrate the test equipment to be used; or the organisational procedures for ensuring that the test equipment is maintained and correctly calibrated
- how to conduct any necessary checks/tests to ensure the integrity, functionality, accuracy and performance of the system and its dependences
- how to recognise defects (such as under or over performance)
- the various fault-finding techniques that can be used if the system fails the test
- displaying/recording test results and the documentation to be used
- how to interpret the test readings obtained and the significance of the readings gained
- how to analyse the test results
