Bollinger Shipyards Lockport, La., has delivered the Seacor Madison, the first of three 207-ft., 4750 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), the SEACOR WASHINGTON and SEACOR JEFFERSON.
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. “For example,” said Mike Ellis, chief operating officer of Bollinger, “the SEACOR MADISON can carry 6,223 barrels of liquid mud and has 6,000 cubic feet of storage for dry bulk mud. Combine these capacities usually found in OSVs from 220-240 feet with the lower operating costs of a 207- foot vessel and you have a boat that will be very efficient. It has separate pump systems that can handle different liquid mud products without danger of contamination. And, all pump systems can be operated through a central control system in the pilothouse, which also accommodates the boat’s ABS (American Bureau of Shipping) classed DPS2 dynamic positioning system.”
Ellis said, “The design is a result of close cooperation with Seacor and Bollinger’s design and engineering teams.” The pilot house is located further forward and features 360 degree visibility free from interference by stacks and includes touch screen computer displays for the boat’s dynamic positioning system and other control systems. He added, “Seacor’s successful experience with Bollinger’s repair facilities and past new build programs was a big factor in the decision to team with us on these large capacity 220 series vessels. Bollinger has a long-standing relationship with Seacor and we will continue to pursue innovative solutions to their needs domestically as well as internationally.”
Seacor’s President, Milt Rose, said, “The SEACOR MADISON and her sister vessels were designed to provide maximum capacities of key cargoes such as liquid mud, as well as to provide redundancy in transfer and operating systems so as to assure cargo deliverability. In addition to the vessel’s cargo capabilities, great care has gone into the design of the vessel to incorporate features that will significantly minimize the possibility of spills of fuel and liquid mud cargoes. The SEACOR MADISON is a vessel that offers reliability, maximum capacities, and a design for safe operations.”
Overall, SEACOR MADISON is 207-feet long, 53-feet wide and 19-feet deep. Light draft is 6.5 feet; loaded draft is 16.2 feet.
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 370 kW generators driven by two Caterpillar 3408 diesels produce electricity. The boat is also equipped with a 95 kW generator as part of its Safety of Life At Sea (SOLAS) classification. Two 1,000 horsepower 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.
Her cargo deck has a clear area of 6,525 square feet capable of carrying 1380 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.
A partial list of electronics and controls includes: a Simrad DPS-2 vessel control; a Furuno GPS; SteerProp engine controls; two JRC radars
; an A3 GMDSS radio system; a Bogen public address system; OFE Globe Offshore internet E-mail; a Standard Horizon VHF and loudhailer, and a JRC speed log.
Other equipment includes a Coastal Marine anchor windlass, a Stang 1,900 GPM fire monitor with a Crane Demming
pump driven by a Caterpillar 3508B diesel; six (6) 16-man inflatable life rafts; a SOLAS rigid inflatable boat (RIB) with a 50 HP motor, and a Headhunter 36-person marine sanitation device.
Air-conditioned and heated accommodations are provided for 26 people in 11 cabins, all with private heads. A double bed hospital is also included and the boat’s galley can serve 12 persons at a time.
SEACOR MADISON is U. S. flagged and classed by the ABS Maltese Cross A1, AMS, DPS2 and documented by the U. S. Coast Guard under sub-chapter L OSV & I Misc. Vessel and carries full SOLAS certification.
