Halter Converts Supply Boat

To Crabber/Processor In 90 Days

A 180-foot supply vessel which once served offshore oil and gas rigs in the Gulf of Mexico was converted in 90 days by Halter Marine's Moss

Point, Miss., shipyard to a crabber/ processor for use in the Bering Sea.

The "new" Northern Enterprise began life in 1980 at Halter's Moss

Point yard as the Summer Sun. She was purchased by her new owner,

Arctic Alaska Seafoods of Seattle in 1987.

John Dane III, president of the

Trinity Marine Group which in- cludes the Halter shipyards, said the abundance of idled offshore oil field boats and their low prices make them ideal for conversion for other uses.

Halter removed the vessel's drill- ing mud tanks below decks and sandblasted, painted, and insulated that area, turning those spaces into a 26,000-cubic-foot refrigerated hold. Miscellaneous offshore equip- ment and the wooden aft deck was removed and replaced with a 1,400- square-foot processing room.

Two hydraulically driven Alaskan

Marine knuckle boom cranes with 50-foot booms on 12-foot pedestals, a hydraulic double pot launcher, a

Marco power block, and a Halter- built picking boom were installed along with stability enhancing roll- ing chocks.

The Northern Enterprise's elec- trical system was also redesigned to support the extensive processing and refrigeration equipment. Two

Detroit Diesel 8V71T engines were added to drive two new 250-kw gen- erators, and a Detroit Diesel 12V92T engine was installed to drive a 425-kw generator.

The boat's propulsion is provided by two EMD 12-567-BC diesels with

Falk 2.98:1 reverse/reduction gears.

The Northern Enterprise is the fourth vessel built or converted by

Halter for the Arctic Alaska Sea- foods fleet. Her Enterprise sisters are the Alaskan, Northwest, and Al- eutian Enterprise. A fifth sister, the much larger 224-foot U.S. Enter- prise will join the fleet soon.
