Bulk Carrier Horyu Maru Delivered

By Hitachi's Ariake Yard

The 132,597-dwt bulk carrier

Horyu Maru, which was con- structed at the Ariake Works of

Hitachi Zosen, was delivered to her owner, Nippon Kisen Co.,

Ltd., recently. The ship will be placed in service between Japa- nese ports and overseas ports in

Australia, Africa, and the North

American West Coast.

This bulk carrier was devel- oped specifically to meet Japanese industry's growing raw material needs. The ship will be used to carry mainly coal and ore. Some measures incorporated to mini- mize fuel costs include a Hitachi

Zosen-developed special nozzle to increase propulsion efficiency, a constant-pressure turbocharged main engine, a turbo power gen- erator with exhaust gas econo- mizer, and long-life paint. Ma- chinery is highly rationalized to save labor through simplification of cargo handling and mooring

Twin Nickum & Spaulding "Schooners7

Join Alaska Fishing Fleet

Utility vessel Graysearch was delivered recently by HUDSHIP to Gray MacKenzie

Company of Bahrain. The 112-ft. boat is powered by twin Detroit Diesel 16V92

NA engines.

GM-Powered Utility Vessel

Delivered By Hudson Shipbuilders

Hudson Shipbuilders, Inc. (HUDSHIP) of Pascagoula, Miss., recently delivered its second ves- sel, the Graysearch, to Gray Mac-

Kenzie Company, Ltd. of Bahrain.

The new vessel will join the al- ready sizable fleet now operated by Gray MacKenzie in the Ara- bian Gulf.

The design is HUDSHIP's standard 112-foot utility vessel hull, with some modifications to suit the owner's particular re- quirements. The forecastle house arrangement has been redesigned to accommodate 10 crewmen in six cabins. The upper house has been extended to accommodate charter's personnel in five two- man staterooms, with separate lounge and messing area.

The afterdeck has a Scott ATO 71!>-ton crane mounted at center- line to service the entire cargo deck. To each side of the crane, are Hydradyne hydraulic winches, giving the vessel a 4-point moor- ing capability.

The Graysearch is powered by twin GM Detroit Diesel 16V92

NA engines with Twin Disc 527 gears with 5:1 ratio. On sea trials the vessel exceeded 10 knots in a loaded condition and logged al- most 13 knots lightly loaded. The auxiliary power is provided by two 50-kw Delco generators pow- ered by GM Detroit Diesel 4-71 engines. Engines are monitored by a 21-point Marine Electrical

Design monitoring system and have Kobelt controls.

The 114-foot "schooner" type crabber/tender/pot fisher Prowler was built by

Mitchel D. Phares Boat Construction Company in Wilmington, Calif., to a Nickum & Spaulding Associates, Inq., design.

The Prowler and the Sablefish — both wide-waisted, house-aft boats termed "schooners" by West

Coast fishermen—recently headed north out of Seattle for the king crab season, their introduction to the working fish fleet. The twin boats joined a growing group de- signed by Seattle naval archi- tects Nickum & Spaulding Asso- ciates, Inc. The boats were built in the Mitchel Phares Boat Con- struction Company yard in Wil- mington, Calif.

Both 114 feet in length and 32 feet in beam, the Prowler will be registered out of Ketchikan and the Sablefish out of Friday Har- bor, Wash. While initially equipped for crabbing, plans call for both vessels to return to Se- attle for installation of specially designed processing equipment and modifications to deck gear to fit the boats for pot fishing.

Both boats have —30 degrees

F air blast freezing units, with freezing holds in the forepeaks capable of freezing 25,000 pounds (continued on page 10) 8 Maritime Reporter/Engineering News
