Bollinger Shipyards Lockport, La., has delivered the Seacor Madison, the first of three 207-ft., 4,750 bhp supply boats to Seacor Marine, Inc., Houston, Tex. It will be followed by two others of Seacor's new President Class offshore support vessels (OSV), Seacor Washington

The boats are part of Bollinger's new 220 Class OSVs that are designed to provide more cargo capacities, more versatility, more options and lower operating costs than larger vessels.

Two Caterpillar 3516B diesels developing a total of 4,750 bhp at 1,600 rpm driving two Steerprop SP25 azimuthing propulsors supplied by Karl Senner, Inc, provide propulsion.

Two 1,000 hp SMI bow thrusters driven by two Caterpillar 3508B diesels aid maneuverability and station keeping. Bow thruster noise is reduced by a Sound Down noise damping system. All of the Caterpillar engines were supplied by Louisiana Machinery, Inc.
The vessel's cargo deck has a clear area of 6,525 sq. ft. capable of carrying 1,380 long tons. Some other capacities are: 169,774 gallons of drill water; 106,129 gallons of ballast water; 155,313 gallons of fuel oil; 2,296 gallons of lube oil; 1,155 gallons of hydraulic oil, and 2,498 gallons of sewage.
