Hitachi-Built Tanker Has

Many Advanced Features

Tanker Yuho Maru, completed recently by the Ariake yard of Hitachi Zosen, is pow- ered by a 20,400-bhp Hitachi/Sulzer 6RLA 90 diesel that gave a trial speed of 16.6 knots.

The 79,999-dwt tanker Yuho

Maru, constructed at the Ariake

Works of Hitachi Zosen, was de- livered recently to the Yuyo

Steamship Company, Ltd. of Ja- pan. The ship will operate be- tween Japan and ports in the

Arabian Gulf and Singapore.

Extensive fuel-saving meas- ures are incorporated in the new ship, including a fuel-saving, low- speed, long-stroke Hitachi/Sulzer diesel engine, model 6RLA90; a turbogenerator utilizing a two- stage, pressure-type exhaust gas economizer; and hull coating of a self-polishing copolymer type.

The cargo oil piping system in- side the tanks is designed to han- dle three different kinds of crude oil. Highly corrosion-resistant cast steel pipe is used in the system.

The ship is equipped and con- structed to conform with SOLAS 1974 and its Protocol of 1978, as well as MAPOL 1973 and its

Protocol of 1978.

Two control rooms—one for en- gine control and the other for cargo handling—have been com- bined into one to reduce person- nel needed, and located on the up- per deck. For cargo handling con- trol, magnetic float level gauges of the explosion-proof type, and pneumacator type level indicators have been adopted to permit mon- itoring of cargo oil and ballast wa- ter tank levels.

The main engine is remote-con- trolled from the wheelhouse, and a sophisticated automatic control and monitoring system is installed to permit 24-hour unattended op- eration of the engine room.

A maritime satellite communi- cations system permits the recep- tion of high-quality audio and telex communications, as well as instantaneous telephone connec- tions.

The Yuho Maru has an overall length of 233 meters, beam of 41.8 meters, depth of 19.6 me- ters, and full-load draft of 12.77 meters (764.4 / 137.1 / 64.3 / 41.9 feet). Classed by Nippon Kaiji

Kyokai, the ship has a comple- ment of 30.
