Installing marine power generation and distribution equipment and systems
Overview
This standard identifies the competences you need to install marine power generation and distribution systems, in accordance with approved procedures. You will be required to use appropriate installation drawings, specifications and documentation to install the various items of equipment. You will be expected to position, align and secure equipment in its correct locations, using the specified/appropriate techniques and termination devices. The equipment will include batteries, generators, alternators, regulators, invertors, transformers, rectifier units, automatic voltage regulators and main contactors/circuit breakers.
Your responsibilities will require you to comply with organisational policy and procedures for the installation activities undertaken and to report any problems with the installation that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with minimal supervision, taking personal responsibility for your own actions and for the quality, accuracy and safety 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 installation techniques and procedures to marine power generation and distribution. You will understand the power supplies being installed and their application and will know about the installation tools, techniques and methods, 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 operations. 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:
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
install, position and secure the equipment and components in accordance with the specification, using appropriate methods and techniques
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
- check that the installation is complete and that all components are free from damage
- complete relevant documentation in line with organisational procedures
Knowledge and Understanding
You need to know and understand:
- the specific safety practices and procedures that you need to observe when working with marine electrical power generation and distribution systems (including any specific legislation, regulations/codes of practice for the activities, equipment or materials)
- the health and safety requirements of the work area where you are carrying out the activities and the responsibility these requirements place on you
- the hazards associated with installing marine power generation and distribution 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 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 (PPE) and protection of the vessel
- 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 interpretation of drawings, standards, quality control procedures and specifications used for the installation (including BS and ISO schematics, symbols and terminology)
- how to carry out currency/issue checks of the specifications you are working with
- the components to be installed and their function within the particular power distribution system
- 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 fasteners for the particular installation 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
- the procedures for ensuring that you have the correct type of tools, equipment, electrical components and fasteners for the activities
- the techniques used to position, align, adjust and secure the components to the system, without damage
- methods of lifting, handling and supporting the components/equipment during the installation activities
- the use of seals, sealants, adhesives and anti-electrolysis barriers and the precautions that need to be taken
- why unit electrical bonding and continuity is critical and why it must be both mechanically and electrically secure
- the procedure for the safe disposal of waste materials
- how to conduct any necessary checks to ensure the system integrity, functionality, accuracy and quality of the installation
- how to recognise installation defects (such as misalignment, ineffective fasteners or terminations, damage or contamination)
- the importance of ensuring that the completed installation is to the category of cleanliness prescribed and of ensuring that any exposed components or pipe ends are correctly covered/protected and warning notices are fitted
- the tools and equipment used in the installation activities and their calibration/care and control procedures
- 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 and where appropriate, the importance of marking and identifying specific pieces of work in relation to the documentation
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
