This is a 750KVA/450V/720 RPM Alterator, Hyundai HFC7 504-14K has been rewinded and maintained by Ha Ha M&S for 6 days.

In-situ rewinding aboard a ship is very different from rewinding in the workshop. The fact that the engine rooms of this type of ship are crammed with machines and equipment causes the alternator to be fixed in its position. Moving the ship to a dry dock and removing a part of the hull was not an option for the customer as the ship could not be taken out of service for a long period of time.

For job like these, a highly detailed preparation is crucial. Not a single item can be forgotten as missing tools and equipment are disastrous for the completion of the job.
