3,800-hp DP-2 OSV from Master Boat Builders

Master Boat Builders , Bayou La Batre, Ala., delivered a 3,800-hp, DP-2 OSV to Abdon Callais Offshore in May.

The addition of the Nicholas P. Callais gives Golden Meadow, La.-based ACO a fleet of 50 vessels, all designed and built by Master Boat over the past 13 years.

“This is a very successful family-owned business. We have a very unique way of conducting our daily operations,” said Bill Foret, president of ACO. “We think our integrated ISO 9001/2008 and our quality safety management system makes us a better company.”

Tankage on the 200′ × 48′ × 16′ OSV include 128,000 gals. fuel; 4,280 bbls. liquid mud; and 4,000 cu. ft. bulk mud in four 1,000-cu.-ft. tanks. The rear cargo deck measures 146′ × 40′ and can carry up to 1,100 LT of freight.

Main propulsion comes from twin Caterpillar 3512C diesels, producing 1,911 hp at 1,600 rpm each. The Cats are matched up with Rolls-Royce Hung Chin 82″ × 70″, 5-bladed wheels through Twin Disc MGX-5600 marine gears with 5.04:1 reduction ratios. The propulsion package pushes the Nicholas P. Callais along at a cruising speed of 11 knots with a full load. (The boat topped out at 13 knots during sea trials.)

The new OSV was fitted with three 500-hp Omega 1170 electric motor (through frequency drives) thrusters.

Ship’s service power comes from a pair of Cat C32 parallel gensets, sparking 910 kw each.

Twin Disc handled the wheelhouse controls and Gulf Coast Air & Hydraulics supplied the Jastram split-rudder steering system. The electronics suite was supplied by New World Electronics , and the DP-2 system is from Kongsberg .

The Nicholas P. Callais is ABS-classed Maltese Cross A-1, AMS DPS-2, USCG-certified Subchapter L, under 100 gross tons. The steel OSV has a crew/passenger capacity of 40, with 30 berths.

“This is the best shallow-draft, high-capacity fleet in the country,” said Foret, who is obviously proud of his fleet. But he said he is more impressed with ACO’s employees. “We develop our people. Our employees are the real success story of this company.” – Ken Hocke
