Hitachi Zosen Completes
275,993-Dwt Tanker Sea Duke
Hitachi Zosen's Ariake Works in Japan re-
cently completed the 275,993-dwt tanker Sea
Duke, a very large crude carrier (VLCC) which
was delivered to the owner, Resilience Shipping
Company Limited.
The 1,070-foot-long by 185.7-foot-wide tanker
is a sister ship of the M/T Sea Prince, which was
completed and delivered this past May.
The vessel is powered by an HZ MAN B&W
6S80MC type main diesel engine with a maxi-
mum 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, a design
feature that achieves highly improved propul-
sion efficiency. To cut fuel expenses, fuel con-
sumption is greatly reduced by the use of a low-
rpm, long-stroke, turbocharged diesel engine op-
erated in a derated mode.
The cargo oil pipes are arranged to allow
simultaneous storage of three types of crude oil,
s.
The Sea Duke's Hitachi Zosen-MAN B&W 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.
and are coated with high-grade paint to ensure
corrosion protection. The tanker is equipped
with a self-stripping system to shorten cargo
loading time and reduce labor costs.
Remote-control level gages for the cargo oil
tanks and the water ballast tanks enable tank
levels to be monitored even from the cargo con-
trol room.
