Rolls Royce Engine Passes Initial Tests The new Rolls-Royce MT30 gas tur- bine has reportedly successfully run for the first time at the company's Bristol, UK site. "This is a great milestone in our drive to bring leading edge, proven, aero gas turbine technology to the marine marketplace," said Saul Lanya- do, president, Rolls-Royce Marine. Planned for availability early in 2004, the MT30 has a power rating of 36 MW, but is said to be comparable in efficien- cy to 25 MW units. A rating of 36 MW is available at the power turbine output shaft at ambient air temperatures up to 26 degrees C, with a corresponding spe- cific fuel consumption of 0.207 kg/kWh. The unit burns DMA, a wide- ly available marine fuel. Under tropical conditions of 32 degrees C air tempera- ture, the output is 30 MW. An eight-stage variable geometry axial low pressure compressor driven by a single stage IP turbine feeds air to the high pressure spool, comprising a four- stage compressor and single stage HP turbine. The MT30 will be supplied as a package on an optional bedplate with an acoustic enclosure, which is fitted with automatic fire detection and extinguish- ing, and houses the auxiliaries and the inlet and exhaust diffuser. The complete unit weighs about 22 tons dry, or 27 tons with bedplate, and measures 30 x 12 x 13 ft. (9.1 x 3.8x4 m). The engine — which will target both commercial and military markets — has 80 percent commonality with the Trent 800 aero engine, which, since entering service in 1996, has logged more than two million flying hours and achieved 99.9 percent reliability. The MT30 is the 11th engine type Rolls-Royce has derived from core aero engine technolo-gy- Circle 199 on Reader Service Card www.maritimereporterinfo.com Crescent Tankships Orders Product Tankers Crescent Tankships, part of the U.K. shipping group Crescent, has ordered two innovative 3,500 dwt chemical and oil tankers from the Rousse Shipyard, Bulgaria. The order, accompanied by a series of options, follows the acquisition by Cres- cent of Camilla, a 1,880 dwt high spec- ification product tanker. "These orders, our first newbuildings since 1989, and the acquisition of the Camilla, show our confidence in the future of the clean products market in October, 2002 Europe," says Rob Bennett, managing director of Crescent Tankships. "We believe this high intensity market will become even more demanding, so with the backing of the Clipper Group, we are moving to ensure we have the right vessels to meet the future high expecta- tions of major charterers in these trades." For delivery in fourth quarter 2003, the two newbuildings will be LR class and British flag. They will have twin engines, twin screws, twin rudders and a high degree of operational redundancy, in addition to being double skinned throughout their length. "These vessels reflect a growing demand for segregated ballast in smaller ships, which cuts down on the likelihood of pollution and also reduces in port time. The double skin in the engine room area protects the bunker spaces."
