Diamond Services Comes Back to Cummins Power

The people at Diamond Services Corporation, based in Morgan City Louisiana, like powerful boats and they like to test the limits with new technology. They are also prepared to shop around for engines and propulsion systems. With two new 170x30-foot crew boats currently under construction at Swift Ships in Morgan City, Diamond Services, a subsidiary of the Carline Corporation, is becoming well established as an operator of the new generation large crew boats. They launched the first of this class, the "Paula Kay", in May of 1997 with four Cummins KTA38-M1 main engines with a rating of 1000 HP each. The engines drove Hamilton HM571 water jets to give the boat a light speed of 29 knots or 28 knots with 64 passengers, crew, ship's fuel, water and a 30 ton deck cargo. In a subsequent boat, the185-foot "Kristin Grace", the firm tried another manufacturer's engines. But for the currently building 170-footers they have returned to the Cummins KTA38 base. "We have a lot of hours on the "Paula Kay's" KTA38-M1 engines," says Diamond Services Mike Swiber, "and we like the service and support that we have had."

For the latest boats, the company chosen four of the newer KTA38-M2 model V-12 Cummins engines that are delivering 1350 HP each through ZF BW255 gears. At 1000 HP, the "Paula Kay's" engines were at the upper limits of the HM571 Hamilton jet's horsepower ratings. For the new boat, the more powerful engines are being linked to Kamewa A-56 jets. With 5400 HP driving through larger jets, Swiber expects to increase the speed to 32 knots light ship. Because the Diamond services boats have been successful in biding Mexican contracts, the new boats are being built with 75 rather than 64 passenger seats.

The first of the new boats is scheduled for a December 2000 delivery with the second following in February 2001.
