Hitachi Zosen Completes VLCC Sea Prince'

The Sea Prince, a 275,782-dwt tanker, was recently completed at Hitachi Zosen's Ariake Works. The 1,070-foot-long by 185.7-foot-wide very large crude carrier (VLCC) was christened and delivered to the owner, Seatruth Shipping Company S.A.

The tanker is powered by an HZ MAN B&W 6S80MC type diesel engine with maximum continuous output of 23,090 hp x 73 rpm, producing a speed of 14 knots. It is equipped with a Hitachi Zosen-developed Super Stream Duct nozzle in front of the propeller and a large bulbous bow below the bow waterline and features self-polishing copolymer (SPC)-type antifouling paint which reduces the hull's frictional resistance and ensures long-term fouling prevention. Highly improved propulsion efficiency is thus achieved.

To cut fuel expenses, fuel consumption is greatly reduced by the use of a low-rpm, long-stroke, turbocharged diesel engine operated in a derated mode.

Remote-control level gauges for the cargo oil tanks and the water ballast tanks enable tank levels to be monitored even from the cargo control room.

The main engine can be operated from the wheelhouse with microcomputer- based remote control equipment. Automated monitors permit navigation without operator attendance in the engine room.

The Sea Prince has a complement of 30 persons and carries the classification NV.
