Propulsion Technology ZF Helps to Harness Spirit of Ontario's Power ZF Marine gears are on board the Spirit of Ontario, helping to harness the power of what is reported to be the most powerful fast ferry in the U.S. ZF Marine supplied four ZF 53000-1 NRH non-reversing, horizontal offset trans- missions to mount behind MTU 20V 8000 M70 engines rated at 8,200kW. ZF 53000-1 NRH transmissions are designed to be lightweight, while offering a high power density for top performance. The hardened and ground gear teeth • Last year Austal was awarded a con- tract to build 12 new patrol boats for the Royal Australian Navy (RAN). It is anticipated that these 56-meter vessels will each be fitted with two MTU 16V Series 4000 diesel engines, continuing a long association between MTU and the RAN. "Vessels providing transport, coastal patrol and other military and law enforcement missions perform varied and demanding tasks. We are respect- ed by the World's navies for providing advanced high-power technology, ranging from basic twin-engine plants to high complex and complete systems including diesels and gas turbines," said Bentgen. "The U.S. Marine Corps have been using a large Austal catamaran as a troop and equipment transporter for nearly three years with great success and we have also designed a revolu- tionary trimaran platform for the General Dynamics bid for the Navy's Littoral Combat Ship project," said Pemberton. "We are also currently building 22 naval patrol boats at Austal Ships in Australia."

Each of the four gearboxes on the Spirit of Ontario feature ZF Antiflex Mounting Systems. The design of ZF's Antiflex Mounting System absorbs and reduces stresses on the main housing when the vessel's hull deflects in rough waters. ZF PTO's were also required for this application to con- trol the steering of the vessel's waterjet propulsion system. Circle 8 on Reader Service Card Dependable Long Lasting Power
