HUDSHIP Delivers Twin Supply Vessels To Gray Mackenzie

Hudship Shipbuilders, Inc. (HUDSHIP) of Pascagoula, Miss., recently delivered its third and fourth supply vessels, the Graytrack (shown above) and Graytraverse, to Gray Mackenzie Company, Ltd., Marine Division located in Bahrain. The design is HUDSHIP's standard 120-foot utility vessels with some modifications to suit the owner's particular requirements. The fo'c'sle house arrangement has been redesigned to accommodate 10 crewmen in five cabins. The upper house has been extended to accommodate charterer's personnel in two 2-man, one 4-man and one 1-man cabins.

The afterdeck of each vessel has a National Marine 12.5-ton crane, with 100-foot boom, mounted at centerline to service the entire cargo deck. To each side of the crane are Hydradyne hydraulic winches, giving the vessel a 4-point mooring capability.

Graytrack and Graytraverse are both powered by twin GM Detroit Diesel Allison 16V92NA engines, each rated 600 bhp at 1,800 rpm, with Twin Disc 520 reduction gears. On sea trials the vessels exceeded 10 knots in a loaded condition and logged almost 13 knots lightly loaded. The auxiliary power is provided by two 99-kw KATO generators powered by Detroit Diesel 6V92 engines.

This is said to be the first application for the 6V92 engines as generator power plants. Engines are monitored by a 21 point Marine Electrical Design monitoring system.

The pilothouse was arranged for maximum all-around visibility. She houses an assortment of electronic equipment, which includes one Decca 914C marine radar, one Sailor SSB receiver model R-105, one Sailor SSB transceiver model T-124, one Sailor model RT 144AC VHF transceiver, one Datamarine 2650 depth indicator, and one Sperry SR 130 gyrocompass with repeater.

Both the Graytrack and Graytraverse are built and tested to ABS standards and are classed A-l All Ocean Service. The Graytest, the fifth vessel HUDSHIP has under construction for Gray Mackenzie, is scheduled for delivery in May 1981.
