New MTU-ZF Propulsion Powers Swiftships-Built CO-MAR Crew/Supply Vessel

Swiftships, Inc. of Morgan City, La., has announced the completion of a 120-foot, allaluminum crew/supply boat named C/Raider.

This vessel is the first purchased by CO-MAR Offshore Corporation, also of Morgan City, to employ a ZF 2y2:1 reduction gear.

MTU engines combined with the ZF gears allow the craft to use a larger propeller. This results in the vessel being able to transport heavier loads at higher speeds.

Paul Haines Jr., owner of CO-MAR, stated: "Many of our vessels are powered by MTU engines. However, this is our first experience using ZF gears with the MTU engines.

"We have to say that the C/Raider is one of the most impressive boats we've taken delivery on in terms of performance and ease of handling." Mr. Haines acknowledged that CO-MAR has contracted for four sister vessels with the MTU ZF power gear propulsion units.

A twin-screw vessel, the C/Raider has a propulsion package consisting of two MTU 12V331 engines and ZF gears. A Delco 30-kw generator is driven by two Detroit Diesel 3-71 auxiliary power engines. On its sea trial, the crew/supply boat attained speeds up to 25 knots.

Having passed United States Coast Guard inspection, the C/Raider is certified to carry 65 persons, aviation fuel, and corrosives. It also provides living quarters to accommodate a five-man crew.

With a cargo deck size of 58 feet by 16 feet, C/Raider's cargo capacity above deck Using MTU-ZF power gear propulsion units, the C/Raider, a crew/supply boat built by Swiftships, Inc.

is 110 long tons, while below deck its capacity is 52 tons. It maintains a 6-foot draft loaded, 3-foot light.

The tanks hold 3,740 gallons of fresh water, 13,350 gallons of drill water, 500 gallons of drinking water, and 4,000 gallons of fuel which gives the vessel an endurance of 40 hours.

Columbian supplied the propeller, a fourblade, 42-inch by 38-inch Crewboat Bronze.

Electronics were installed and supplied by Bibbins & Rice. They include a Furuno radar, two radiotelephones, an SSB Drake TRM 1 and a VHF Drake MRF-55, a Texas Instruments TI-9900 automatic Loran, an Impulse 600CV depth sounder, and a Danforth C654C compass.

The vessel is equipped with lifesaving gear, full fire-fighting capabilities, and airconditioning and heating throughout. It also carries a full complement of other safety features and navigational equipment onboard.

Swiftships' project engineer, Calvin Le Leux, reports that C/Raider passed all tests and will be placed into petroleum operation in the Gulf of Mexico.
