Assisting in the installation of marine electrical and electronic equipment
Overview
This standard identifies the competences you need to assist in the installation of marine electrical and electronic equipment, in accordance with approved procedures. The installation activities will involve installing equipment at component or unit level, on a variety of marine electrical assemblies and sub-assemblies, such as single, three phase and direct current power supply and control systems, motors and starters, switchgear and distribution panels, control systems, communication systems, computer systems, weapon systems, navigation systems, sensor systems, computer control systems, lighting and alarm systems, electrical plant, luminaires and domestic electrically powered equipment.
Your responsibilities will require you to comply with organisational policy and procedures for the installation of the marine electrical equipment and to report any problems with the installation activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people.
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. Where team working is involved, you must demonstrate a significant personal contribution during 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 provide an informed approach to applying the appropriate electrical and electronic installation techniques and procedures. You will have an understanding of the basic knowledge behind the equipment being installed, and its application and will know about the installation equipment and fastening devices, in adequate depth to provide a sound basis for carrying out the activities to the required specification.
You will understand the safety precautions required when carrying out the installation of the marine electrical and electronic equipment, especially those for ensuring that any power supplies are correctly isolated and locked. 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:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- follow all relevant drawings and specifications for the installation being carried out
- use the correct tools and equipment for the installation operations and check that they are in a safe and usable condition
- assist in the installation, positioning and securing of the equipment and components in accordance with the specification
- ensure that all necessary connections to the equipment are complete
- deal promptly and effectively with problems within your control and report those that cannot be solved
- complete relevant documentation, in accordance with organisational requirements
- check that the installation is complete and that all components are free from damage
Knowledge and Understanding
You need to know and understand:
- the procedures to be carried out before starting work on the installation (such as obtaining permits to work, obtaining and complying with risk assessments and other health and safety requirements)
- the health and safety requirements of the work area where you are carrying out the installation activities and the responsibility these requirements place on you
- the hazards associated with the installation of marine electrical equipment and systems, and with the tools and equipment used and how they can be minimised
- 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 protective equipment that you need to use for both personal protection (PPE) and protection of the equipment or system being installed
- 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 the job instructions, drawings and specifications used for the installation
- the items, circuits and components to be installed and their function within the particular marine equipment/system being installed
- the various mechanical fasteners that will be used and their method of installation (including threaded fasteners, special securing and locking devices)
- the importance of using the specified electrical terminations/connections/fasteners for the particular installation process, and why you must not substitute others
- why securing devices need to be locked and identified and the different methods that are used
- the quality control procedures to be followed during the installation operations
- procedures for ensuring that you have the correct tools, equipment, electrical components and fasteners for the activities
- the techniques used to position, align, adjust and secure the equipment, components and circuitry to the vessel/compartment structure without damage
- methods of lifting, handling and supporting the components/equipment during the installation activities
- the use of seals, sealant, adhesives and anti-electrolysis barriers and the precautions to be taken
- why unit electrical bonding/earth prevention and continuity is critical and why it must be both mechanically and electrically secure
- the procedure for the safe disposal of waste materials
- the importance of ensuring that the completed installation is to the category of cleanliness prescribed, that any exposed components or pipe ends are correctly covered/protected and that warning notices are fitted
- 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 with the installation operations and how these can be overcome
- the recording documentation to be completed for the activities undertaken
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
