Description

The electrical distribution system in ships demonstrates the sources of electrical power and the essential loads found onboard. These systems describe the selection of plants for generating electric power on vessels. Electrical maintenance helps to keep the equipment in excellent running condition, reduces downtime and increases cost savings. Generally, they follow a time-based maintenance procedure. However, they also apply condition-based maintenance for large moving machines where periodic stoppage and dismantling may cause problems. Shipboard maintenance of electrical and electronic devices is limited to regular monitoring and basic maintenance. This entails conducting regular watchkeeping checks, investigating abnormal running conditions, and changing worn-out or defective parts per the SOP and the manufacturer's instructions. In the case of a total failure or breakdown, you require a shipboard crew member to change a motor, starter parts, or electronic cards that control certain operations based on time sequence or logic ingrained in the circuitry. This course includes basic maintenance procedures that build your troubleshooting capability and basic maintenance skills.

The course then discusses the causes of short-circuits and earth faults and the common locations of earth faults in systems. Explore the direct current wire distribution system and each section's content of the direct current switchboards. Study the main electrical power sources on ships and the main switchboard functions, maintenance of DC machines and the performance load test of a direct current generator. Learn about the rewinding of the field coil and the rewinding of the DC machine armature. We investigate the open and short circuit tests of an alternator in addition to the maintenance of alternators. You will become skilful at the load performance test on 3 phase alternators and the measurement of the insulation resistance value.

The last section of the course will enable you to gain a sound understanding of the high and low voltage distribution on board ships. We outline the dangers of working with high voltage equipment, the risk assessment and the safety requirements of the high voltage system. Compare the HV supply and LV supply onboard ships in addition to the emergency power distribution of vessels. We cover the methods and procedures for maintaining the induction motor and enable you to determine the slip for 3-ph Squirrel Cage Induction Motor and the Brake Test for 3-ph Induction Motor. Analyze the reconditioning of the silica in the transformer's breather and the estimation of voltage regulation and efficiency. Study the periodic maintenance of transformers, the rewinding of small transformers, and transformer oil tests. Discover how to service a universal motor and the maintenance of cables, safety procedures for busbar inspection and maintenance. Lastly, you will learn about the care of carbon brushes and other associated technology of electrical maintenance. This course will be of significant interest to students, researchers, marine engineers, electricians, and anyone interested in the distribution system and maintenance of marine electrical equipment.
