High Voltage (Operational Level)
This course is suitable for marine engineer officers, electrical or electro-technical officers, engineer surveyors and marine superintendents. The training gives seafarers the essential education and training in high voltage (HV) installations to meet the knowledge, understanding and proficiency requirements as set out in STCW 2010 Table A-III/1 for electrical, electronic and control systems at the operational level.
The course is a blend of classroom and practical training using dedicated facilities to enable students to achieve the following training outcomes:
- Knowledge of the arrangement and protection of HV installations on board a vessel, including what is considered to be high voltage, typical voltages found on board ship, the reasons why modern vessels are equipped with high voltage generators, the difference between insulated and earthed neutral distribution systems, which circuits will operate at high voltage, and the function of the protection devices and their sequence of operation.
- Knowledge of the safety requirements necessary for HV installations, including the hazards associated with high voltage, the requirements outlined in the HSE publication Electricity at Work safe working practices, the terms ‘authorised and competent’ person, the difference between an ordinary and a high voltage permit to work, the isolation process required to produce a high voltage permit to work, and the importance of a circuit main earth.
