Recently shaft generators are adopted for energy saving in many ships. In this paper, the shaft generator motor with a thyristor inverter is introduced. This shaft generator motor provides not only generator function, but also motor function and is usable for ships propulsion in the event of failure of main engine. The first plant of a generator-propulsion system was installed on 80, 000 DWT motor oil/ore/bulk carrier and we confirmed that the functions of shaft generator and electric propulsion were satisfactory.
This multipurpose research vessel was built at HAYASHIKANE SHIPBUILDING & ENGINEERING CO., LTD. YOKOSUKA SHIPYARD for the purpose of mainly fishery and ocean research in compliance with the order from KUWAIT INSTITUTE FOR SCIENTIFIC RESEARCH which is under direct control of Kuwait government.
