NEW TECHNOLOGY The recently patented hydro-propelled ship would currently seeking a builder for the vessel. only operate the propulsion turbines, but also to drive a pair of revolving restaurants placed atop the hull. The concept of the propulsion tur- bines calls for the use of a 25,000-hp engine for the propulsion system to function properly. The designer claims the vessel is designed to travel require a 25,000-hp powerplant. The inventor is up to 50 knots or more. The vessel is designed as a multi- activity passenger ship, featuring a wide beam to accommodate a full range of facilities.For full details on the hydro-powered ship, Circle 18 on Reader Service Card Hydro-Propelled Ship Concept Receives Patent Cernier, is designed to incorporate a pair of propulsion turbines affixed to a double hull of the ship in a catamaran configuration to drive the vessel. Each of the turbines are designed to be placed inside an elon- gated tubular housing, which in- cludes a water intake port and a water exit port. A shaft runs through the center of the housing, and is operated by a power-generating mechanism. A plurality of rotors are attached to the shaft, and when the shaft is rotated, the rotors will squeeze, compress and force water from the intake through the water exit port, effectively creating water jet propulsion. A power plant housed within the hull is designed to not The inventor of a patented hy- dro-propelled ship is currently seek- ing a manufacturer to fabricate the vessel on a national and interna- tional basis.

The unit provides global telephone, fax and data for boats as small as 35 feet (10.7 m) through the Inmarsat-M digital satellite service. For more information from Mackay, MTU Friedrichshafen Receives DIN ISO 9001 Certification The quality assurance system of MTU Friedrichshafen was awarded approval in accordance with DIN ISO 9001. A NACCB (National Accreditation Council of Certifica- tion Bodies) certificate for the Brit- ish market was issued at the same time. Det Norske Veritas (DNV) District Manager Reidar Nyrerod presented the document to MTU Vice President Dr. Gerd-Michael Wolters, and the company deems the certification important for its image on the international market. MTU Debuts New Magnetic Ranging Facility Eberhard Sohn, MTU Friedrichshafen's general manager of technical services, recently handed over a new magnetic ranging facility on the north side of the Friedrichshafen airstrip to Klaus Schedl, head of electronics. MTU needs the plant for engines destined for minehunter vessels. The indi- vidual ferro-magnetic parts are treated to produce the smallest pos- sible permanent magnetic signature. The ranging track, in order to simulate the earth's magnetic field for any given location, is equipped with a number of coils which gener- ate the required magnetic field when subjected to corresponding current. The resulting values are used by the customer to design their system. Saying that there are only two such facilities in Germany, MTU also car- ries out service contracts for other customers, investigating the prop- erties of all components of a minehunter's propulsion train.

Applied Composits of Linkoping, Sweden launched a line of shafts made of plastic composites, target- ing the high-speed vessel market where weight reduction is crucial. According to tests, the company claims the shafts not only offer a weight reduction of 70 percent, but are also stronger than steel, allow- ing approximately 10 times more torque weight to be transmitted. Composite shafts have been in operation for several years in the Swedish Navy's test vessel SMYGE, reportedly without showing fatigue signs.
