GE Turbines Ordered For SeoJet Ferries • utilizing the total beam to keep roll acceleration to a minimum • the natural frequencies for heave, pitch and roll are kept separate to avoid interference between them in a seaway. The semi-SWATH hull form has a very small added resistance in seaways (less than four to five per- cent in significant wave heights up to 6.5 ft. (2 m). This ensures the vessel's ability to keep to sailing schedules, even in rough seaways. The model was tested in shallow water to ensure that the vessel will be able to operate in a seaway where a part of the route passes through shallow water, without any prob- lems in keeping to the schedule. The test showed that extra power is needed for continuing acceleration from 16 to 21 knots. The Power "This order marks the first use of GE's aeroderivative gas turbines in the fastest growing segment of the fast ferry market, specifically the 20 to 26-MW power requirements, which traditionally applies diesel engines for propulsion power," said John Ferrera, vice president, Eu- rope, Middle East and Africa, GE Marine & Industrial Engines (M&IE). "With penetration into this power range of the catamaran fast ferry market, we see unlimited potential for all of GE's aeroderivative gas turbines. The Sea Jet marks the first fast ferry to be powered exclusively by LM1600s." The two SeaJet fast ferries will each have propulsion packages with a total power output of 24,800 kW. The gas turbines will be manufac- tured by M&IE at its Lynn, Mass. plant; the propulsion system pack- ages will be built at Kvaerner Energy's Agotnes facility on the west coast of Norway.

CanaDansk: Patent Pending On CanaDansk Systems Inc. was es- tablished to provide the measure- ment and correction of drive shaft systems and other associated ma- chinery. CanaDansk seeks to pro- vide clients measurement, diagno- sis and correction. Specifically, mea- surement of drive shafts and flanges, and measurement of hull flexibility; diagnosis of alignment, noise and mplified Measurement System vibration; and correction where needed. To achieve its goal, CanaDansk has developed a system that simplifies the measurement of shafts, flanges, gearboxes and gen- erators. And although the system was developed for marine equip- ment, it can be adapted for use with other industrial equipment. The CanaDansk technique is patent pending. The system uses a digital laser beam in conjunction with a computerized gyro technique which provides the client with printouts of all X-Y and flange diagrams. It takes a team of two technicians to perform all measuring, diagnosis and correction, and the work is all completed while the vessel is in water.
