A VLCC STEAM-TO-DIESEL CONVERSION WITH TWIN GEARED LOW SPEED ENGINES

The "Amoco Seafarer" is a single-screw 273,263 tonne d.w. tanker built by Mitsui and delivered to her original owner in 1974 as the "Polybritannia". The VLCC is 318 m long (b.p.), with a moulded beam of 56 m, a moulded depth of 26.4 m, and a draught (extreme) of 20.586 m. The re-engining plan was developed on a design concept basis which emphasised the following points: Adoption of crosshead diesel engine offering low fuel oil and lubricating oil consumptions, Maintenance of the safety and manoeuvrability of the ship, Minimisation of alterations in the engine-room arrangement and hull construction. The existing main propulsion steam turbine and reduction gear will be removed and replaced by two sets of 12-cylinder Mitsui-B & W L55GFCA low speed engines coupled to a Stal-Laval type reduction gear. The principal particulars of the propulsion plant before and after conversion are indicated and the engine-room arrangements before and after re-engining are shown in the arrangement drawings which are included.
