Bender Shipbuilding Delivers Three 192-Foot Supply Vessels To State Boat

Bender Shipbuilding & Repair Co., of Mobile, Ala., recently delivered three, 192-foot supply vessels to State Boat Corporation of Houston, Texas.

The sisterships are named the M/V State Glory, M/V State Chief, and the M/V State Belle.

Built to ABS classification and U.S. Coast Guard certification for worldwide service, each vessel has a clear deck area of 130 feet by 31 feet with a cargo capacity of 705 short tons.

Other capacities include: 4,000 cu. ft. of bulk mud carried in four Smatco PNU tanks; 1,300 barrels of liquid mud ; 70,000 gallons of fuel oil; 2,000 gallons of lube oil; 12,500 gallons of potable water; and 230,000 gallons of ballast water.

The vessels, designed by Y.K.

Mok, are of steel, double chine construction. They are twin-screw and each measures 192 feet by 40 feet by 14 feet.

Each is powered by two Caterpillar D399 TA diesel engines, each of 1,125 hp at 1,225 rpm, each engine driving a stainlesssteel Michigan Wheel propeller through Reintjes reverse reduction gears, model WAV1440, having a 4.0:1 ratio. The engines deliver a service speed of 12 knots.

Engine controls are three-station pneumatic by Wabco. Steering is supplied by an electric over hydraulic system from SSI consisting of two 10-hp electric drive hydraulic pumps and three control stations — forward pilothouse, aft pilothouse, and aft fo'c'sle deck. Electricity is provided by International Electric 75-kw generators 225/450V, 60 c/s, at 1,200 rpm powered by two Detroit Diesel engines model GM6-71.

The main fuel oil pump on each vessel is a Goulds model 3405, 4-inch by 6.5-inch, with an 11.5-inch impeller delivering 450 gpm. Additionally, each vessel is equipped with a Viking HL4124, 30-gpm fuel oil transfer pump.

An Alfa Laval MAB-103B fuel oil centrifuge is supplied.

Each vessel is equipped with a 300-hp Murray & Tregurtha bow thruster, model BT340 powered by a GM8V-71 diesel engine delivering 310 hp at 2,100 rpm through a Twin Disc MG509 gear having a 1.454:1 ratio.

Two Goulds 3405 pumps operate the ballast system; a Deming 2895 electric pump operates the potable water system; and an ITT Marlow 2CR13EL pump handles the sewage holding tanks. Two Quincy model 340 air compressors are supplied on each of State Boat's new vessels, as are two 1,500-pound Danforth anchors and an HBL model LDW 1.25E windlass. The vessels' coatings are by International Paint.

Electronic and navigation aids include a Sperry 8T autopilot; Furuno FR 701 radar; and Henschel sound-powered telephones.
