Abstract
Due to drastic soaring of fuel oil prices and petroleum supply crisis, the needs to review the effective use of oil have been the most important subject in the world shipping industries.
Under such circumstances, the conversion of steam turbine plants of existing VLCC or ULCC to more efficient internal combustion engines of the diesel type have been studied seriously and earnestly among ship owners of domestic and foreign countries.
Introduced as follows are the outline of IHI's recent achievement and experience of re-engine works of the “MOBIL HAWK”, one of the VLCC's owned by Mobil Shipping and Transportation Company, where the original 36, 000 SHP steam turbines were replaced successfully with two sets of new IHI-S.E.M.T. Pielstick 12PC4V medium speed diesel engines of 18, 000 PS each.
