IHI Delivers VLCC 'Nissho Maru' To Idemitsu Tanker Company

Ishikawajima-Harima Heavy I n d u s t r i e s Company (IHI) recently c o m p l e t e d the 257,882- dwt tanker Nissho Maru (shown above) for Idemitsu Tanker Company of Tokyo. The new ship is the first vessel delivered by IHI's Kure Shipyard this year, and the first tanker of over 200,000 dwt built by IHI since April 1977 when the 274,348-dwt Texaco Caribbean was completed.

Among the outstanding features of the Nissho Maru are the cargo control room and the engine control room, which are normally located on the boat deck and in the engine room, respectively, arranged in the same compartment near the living quarters.

This makes central control possible during cargo handling, and helps to rationalize the communication and operation between the deck and engine departments.

A data logger, which displays machinery and equipment operating data on its character display and can also record them automatically, is provided in the engine control room.

The IHI/Sulzer type 9RLA90 main engine is a slow-speed diesel with a maximum continuous rating of 32,400 bhp at 98 rpm and with low fuel consumption. While under way the waste heat of the main engine exhaust is recovered to drive the turbogenerator.

Service speed at full load is 14.5 knots. A MARISAT system provides t e l e p h o n e communication with anyplace in the world.

Windlasses and mooring winches are driven by a centralized electro-hydraulic power supply that provides ease of operation and lower maintenance. Eight dedicated ballast tanks with a total capacity of 83,700 cubic meters meet the SBT (Segregated Ballast Tanks) provisions under i n t e r n a t i o n a l marine pollution prevention regulations.

Nissho Maru has an overall length of 340.60 meters, beam of 54.50 meters, depth of 28.00 meters, and draft of 19.70 meters (1,117.44 by 178.8 by 91.86 by 64.63 feet). The big vessel is operated with a complement of only 24 persons.
