Abstract：To solve the offshore platform generator site overhaul problem，it is necessary to apply the generator onshore maintenance technology on the offshore platform. The on-line maintenance strategies and methods of offshore oil gas platform main generator were generalized，the generator rotor core-pulling scheme was preliminary explored，the several common fault forms and solutions after generator extended operation were concluded，and finally the generator normal operation was achieved. The study results lay the foundation for sit maintenance of all types of generators.
