SHIP'S GENERATOR GETS RUNNING REPAIRS WHILST AT SEA

摘要

Large civilian ships rely heavily on electrical power - from lighting and communications through to food and entertainment. Recently constructed cruise ships also rely on electrical propulsive power, so the loss of generator power has the potential to cause concern on both accounts. A large cruise liner recently experienced a generator failure and, on inspection, the ship's maintenance engineering team determined that the 7.5MW generator had a winding fault which would require a complete strip-down and new windings to be manufactured and installed. With experience in completing high voltage generator repairs in-situ, Sulzer took up the challenge. A closer inspection of the stator revealed that the OEM design of the coils had a flaw and that had caused the generator to fail. Sulzer suggested a modification to the design to ensure that a similar failure would not reoccur and this was incorporated with the rest of the coil design details and sent to Sulzer's Birmingham Service Centre in the UK, where the coil shop started work on manufacturing the new coils.
