displace about 404 tons at full load, are powered by two Detroit Diesel 12V71TI diesel engines that develop a total of 850 shp. Detroit Diesel engines also power two Halter Marine-built Ecuado- rian Navy patrol boats. The 44-foot drug interdiction boats are each fit- ted with two military rated Detroit Diesel 8V71TI diesels driving through Twin Disc 509 down angle gears which give the boats a service speedof 26 knots. Danish Osprey 55 Class fast off- shore patrol boats delivered last year by Danyard, are each powered by two MAN B&W Diesel 12V 23/50 diesel engines, supplied by Alpha Diesel of Frederikshavn, Denmark, with 23V020 reduction gears, con- trollable-pitch propeller equipment and Alphatronic remote control. The craft can reach speeds of more than 20 knots. Twin MAN B&W D2840 LE die- sel engines rated at 635 hp at 2,300 rpm power PT Class patrol boats built by Singapore Shipbuilding and Engineering for the Government of Brunei Darussalam for the Royal Brunei Police Force. The 48-foot craft can obtain speeds of about 33 knots. Tempest Marine-built USCG fast coastal interceptors are powered by a pair of turbocharged and after- cooled Caterpillar 3208T diesel en- gines, which produce a combined 750 hp at 2,800 rpm. The craft are fitted with Twin Disc reduction gearing and Record propellers and can obtain speeds in excess of 43 knots. PROPELLERS, THRUSTERS & WATERJETS One of the leading suppliers of controllable-pitch propellers to the U.S. Navy is the Bird-Johnson Company, Walpole, Mass. Bird- Johnson propellers have been se- lected for the Arleigh Burke, the lead ship of the new class of Navy Aegis destroyers, aboard Ticondero- ga Class cruisers, Henry J. Kaiser Class oilers, Landing Ship Dock ves- sels and Mine Countermeasure Ships. Last year, Bird-Johnson was se- lected to supply two 23-foot, six- bladed propellers for the lead ship of the AOE-6 Class Fast Combat Support Ships. West Germany's Schaffran Pro- peller Lehne & Co. manufactures CP and monobloc propellers of 3,000 to 7,000 mm to their own designs for all kinds of vessels. One example of a military installation is aboard the FRG Coast Guard patrol boat Falshoft, which is equipped with a three-bladed, 1,200-mm Schaffran CP propeller. A number of international navies, including the Italian, Venezuelan, Peruvian and Iraqi, use Lips CP and reverse pitch propellers. One of the latest U.S. Navy installations is on the Wasp (LHD-1), the lead ship of the amphibious assault class. Schottel propulsion systems— rudderpropellers, thrusters and jets—are in use in naval fleets all over the world. The firm manufac- September, 1988 tures over 20 different types of Schottel Rudderpropellers, a com- bined steering/propulsion unit, cov- ering a power range of 15-5,000 kw (20-7,000 hp). The units are rotable through a full 360 degrees, proving propulsive steering in any direction. Over 19,000 Schottel propulsion units are in use worldwide. Another new U.S. Navy class ship, the MHC-51 coastal mine- hunter Osprey, will reportedly fea- ture Voith-Schneider propulsion equipment. The vessel is under con- struction at Intermarine USA's Sav- annah, Ga., yard. Sulzer-Escher Wyss five-bladed CP and reverse pitch propellers are featured on the FRG's Bremen Class frigates, as well as on a num- ber of Canadian, Indonesian, Saudi Arabian and South Korean naval ships. Three new U.S. Navy Torpedo Test Craft being built by McDer- mott Shipyard, Amelia, La., will be equipped with Omnithruster hydro- jet maneuvering and propulsion sys- tems. The YTTs, -9, -10 and -11, will be fitted with 350-hp Omni- thruster Mark II hydrojet Model JT 700TDs. The hydrojet units will of- fer the craft precise handling, posi- tion keeping and automatic head- ing.
