Master Boat Builders, Bayou La Batre, Ala., has delivered the 221'x48'x18', DP-2 offshore service vessel Seacor Olmeca to Seacor Offshore LLC.

“The vessel is a stretched version of our 200-foot class vessel previously delivered to Seacor,” said Andre Dubroc, the yard’s general manager. “Notable differences are the enclosed bow, Cargo Flex dry bulk system that uses atmospheric tank design which allows the use of rectangular tanks versus the traditional round ‘P’ tanks. This allows the carriage of more product in a smaller footprint. The vessel is able to carry 8,000 cubic feet of dry mud in 4 tanks.”

Built and designed by Master Boat, the new OSV can carry 150,000 gals. of fuel; 6,000 bbls. of liquid mud; and 8,000 cu. ft. bulk mud in four 2,000 cu. ft. tanks. The rear cargo deck measures 155'x39' and can haul up to 2,216 LT of freight.

“The vessel meets the requirements of SPS (Special Purpose Ship) which will allow the carriage of up to 60 people,” said Dubroc.

Main propulsion comes from twin Caterpillar 3512C diesels, producing 1,911 hp at 1,600 rpm each. The Cats are connected to 82"x70", 5-bladed, bronze wheels through Twin Disc MGX-5600 marine gears with 5.04:1 reduction ratios. The propulsion package gives the new OSV a running speed of 11 knots fully loaded.

For added maneuverability, the boat, which has a draft of 15.25', has two Schottel SST-2FP 800-hp bowthrusters and two SST-170FP 350-hp stern thrusters.

Ship’s service power comes from two Cat C-32 powered gensets, sparking 940 kW of electrical power each and twin Cat C-18 powered gensets, producing 425 kW of electrical power each.

Other features include an FFS FiFi 1 firefighting system, GE Seastream DPS-2 system, electronics suite from New World Electronics, Jastram split rudder steering system from Gulf Coast Air & Hydraulics and Twin Disc EC-300DP controls.

The OSV is ABS classed Maltese Cross A-1 AMS DPS 2, SPS, Offshore Support Vessel, ABS Maltese Cross A1 Firefighting Vessel Class 1, certified USCG Subchapter L and I, Solas, ITC, IMO loadline under 1,600 tons.

“Seacor’s acceptance of the 200-foot class was very favorable,” said Dubroc. “And the delivery of the 221-foot class vessel Seacor Olmeca seems to exceed their expectations.”
