Halter Marine

Halter Marine's Moss Point, Mis- sissippi, shipyard completed the conversion of a 180-foot supply ves- sel, formerly used in the offshore oil and gas industry, into a crabber/ processor for owners Arctic Alaska

Seafoods of Seattle.

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 a wooden aft deck were 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 diesel engines were added to drive two new 250-kw generators, 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.
