Renk Tacke Superposition

Gear Unit For Five Shell

Tankers

Renk Tacke GmbH, part of the

MAN group, was awarded the order for the delivery of gear units for the current generation aboard five 300,000-dwt double hull VLCCs by the Daewoo Shipbuilding & Heavy

Machinery Ltd. shipyard in South

Korea. The vessels are intended for the English Shipping Company Shell

International Marine Limited.

Each vessel is driven by a low- speed diesel engine, type 7 RTA 84

T, manufactured by New Sulzer Die- sel, yielding a power of approxi- mately 26.5 MW via a fixed pitch propeller. During the voyage a con- siderable part of the engine power is used for the current generation on board. Propulsion of the generator is effected via a "step-up-gear" to increase the speed and via a "conspeed" planetary superposition gear unit. Both gear units and the generator are attached to the front side of the main engine. The vari- able main engine speed of approxi- mately 50 to 70 min1 is converted into a constant speed of 1,800 min1 (60 Hz) for the generator. The elec- tric power of the generator is 950 kW. Renk Tacke already supplied nearly 200 such superposition gear units in the power range from 550 to 1,800 kW for economic current gen- eration on board.
