HVA512 STCW High Voltage Vessel Systems - Operational

This course provides you with the theoretical knowledge and safety principles of working with high voltage (>1000V) ship installations. You will be prepared for operational responsibilities in a marine electrical power plant of greater than 1,000V.

This course meets the requirements of STCW 1978 as amended, A-III/1 for understanding basic configuration and operating principles of high voltage installations on board vessels.

Course Aim
This course provides students with the theoretical knowledge and safety principles of working with high voltage (>1000V) ship installations. The students will be prepared for operational responsibilities in a marine electrical power plant of greater than 1,000V. This course meets the requirements of STCW 1978 as amended, A-III/1 for understanding basic configuration and operating principles of high voltage installations on board vessels.

Learning Outcomes
On successful completion of this course, students will be able to:

• State that more than 1000V is usually called high-voltage
• State how and why high-voltage installation are used on board ships
• State what voltages are mostly used as high voltage on board ships
• Describe equipment/installations in high voltage systems such as high-voltage generator, distribution board, motors etc
• State the special characteristics and features of high voltage installations in comparison with less than 1000V
• State that high voltage systems are usually earthed via a resistor
• Explain how the presence of earth faults is indicated in a high voltage system with an earthed neutral
• State safety precautions to be strictly observed to prevent accidents when working on high voltage electrical equipment
• State that any operation of high voltage installation must be carried out remotely at places where a certain distance is being kept from the installations
