Carrying out scheduled maintenance on marine electrical and electronic equipment
Overview
This standard identifies the competences you need to carry out scheduled maintenance tasks on marine electrical and electronic equipment, in accordance with approved procedures. You will be required to carry out scheduled maintenance tasks on marine electrical equipment such as single, three phase and direct current power supply and control systems, motors and starters, switchgear and distribution panels, control systems, communication systems, weapon systems, navigation systems, sensor systems, computer control systems equipment and peripheral devices, lighting and alarm systems, electrical plant, luminaires, portable appliances, electrically powered domestic equipment and other specific electrical equipment, in order to minimise down time and ensure that the equipment performs at optimal levels and functions to specification.
Your responsibilities will require you to comply with organisational policy and procedures for the scheduled maintenance tasks undertaken and to report any problems with these activities, or with the tools and equipment that are used 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 activities and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with either a high level of supervision or as a member of a team. You will take personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. When working in a team, you must demonstrate a significant personal contribution to the team activities in order to satisfy the requirements of the standard and competence in all the areas required by the standard must be demonstrated.
Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will enable you to adopt an informed approach to applying scheduled maintenance procedures to marine electrical and electronic equipment. You will have an understanding of the process of implementing scheduled maintenance tasks, the importance of carrying them out at specific times and in the specified sequence, and of recording the outcomes and actions taken. In addition, you will be expected to report where the outcome of the scheduled maintenance identifies a requirement for further investigation or remedial work.
You will understand the safety precautions required when carrying out the scheduled maintenance activities, especially those for isolating the equipment. You will also understand your responsibilities for safety and the importance of taking the necessary safeguards to protect yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- follow the relevant maintenance schedules to carry out the required work
- carry out the maintenance activities within the limits of your personal authority
- carry out the maintenance activities in the specified sequence and in an agreed time scale
- report any instances where the maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
- complete relevant maintenance records accurately and pass them on to the appropriate person
- dispose of waste materials in accordance with safe working practices and approved procedures
Knowledge and Understanding
You need to know and understand:
- the health and safety requirements of the area in which the scheduled maintenance tasks are to take place and the responsibility these requirements place on you
- how to recognise and deal with emergencies and the procedures to be followed (such as methods of safely evacuating and closing down compartments in the case of fire or other major incident)
- the isolation procedures or permit-to-work procedure that applies to the marine electrical equipment being maintained
- the specific health and safety precautions to be applied during the scheduled maintenance tasks and their effects on others
- 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)
- the importance of wearing protective clothing and other appropriate safety equipment (PPE) during the maintenance activities
- hazards associated with carrying out scheduled maintenance tasks on marine electrical equipment (such as live electrical components, stored energy, misuse of tools) and how they can be minimised
- how to obtain and interpret information from job instructions, drawings and specifications used in the maintenance process
- the various checks to be carried out during the scheduled maintenance procedure
- the procedure for obtaining consumables to be used during the scheduled maintenance activity
- methods of checking that components are fit for purpose, how to identify defects and wear characteristics and the need to replace `lifed' items (such as seals, filters and gaskets)
- how to check that any replacement components meet the required specification/operating conditions
- how to make appropriate sensory checks (such as sight, sound, smell and touch)
- the appropriate built in test equipment instructions (BITE) to be adopted during the maintenance activity
- how to make adjustments to components/assemblies to ensure that they function to specification
- the basic principles of how the equipment functions, its operating sequence, the working purpose of individual units/components and how they interact
- how to complete scheduled maintenance records/logs/reports, in accordance with company policy and procedures
- the equipment operating and control procedures and how to apply them in order to carry out scheduled maintenance
- why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
- the problems that can occur whilst carrying out the scheduled maintenance tasks and how they can be avoided
- the organisational procedure(s) to be adopted for the safe disposal of waste of all types of materials
- the extent of your own authority and whom you should report to if you have problems that you cannot resolve
