The largest waterjet so far in the Rolls-Royce Kamewa FF series has now been introduced. It extends the power range of these axial flow aluminium waterjets to 1,800 kW. “As a rough guide, a boat with a twin FF600 installation would have an all-up weight including equipment and fuel of about 60 tons for optimum performance,” said Tomas Renlund, director of the aluminium waterjet business. “But since we tailor the impeller to suit the application and can customise this type of jet to a considerable extent, each case should be considered individually.” In common with the other units at the smaller end of the Rolls-Royce waterjet range, the FF600 is constructed in aluminium, with the impeller, its housing, shafts and the operating cylinders for steering and reversing made of stainless steel. The inlet duct is fabricated from aluminium sheet to an optimised hydrodynamic profile and the mounting flanges are supplied in two versions; one for welding direct into an aluminium hull, the other for bolting into hulls made of other materials. Reverse and steering hydraulic cylinders are mounted inboard, and close attention has been paid to reducing risk to the environment.The actuating cylinders are anchored to a flange part way along the inlet duct next to the thrust bearing. This flange is designed so that it can be welded to, allowing the jet unit to be incorporated as part of an aft collision bulkhead structure.
BRP has been awarded a $10m contract from the United States Marine Corps (USMC) for its Evinrude multi-fuel engines (MFE). The Evinrude 55 MFE engines with an impeller equipped jet model pump will repower their fleet of F470 Zodiac boats / Combat Rubber Raiding Craft (CRRC) used during small craft operations. The strict procurement requirements of the USMC to secure non-gasoline burning outboard engines led directly to BRP
Long discussed as the embodiment of next-generation marine technology, the Japanese "Techno-Superliner" (TSL) is now a reality. The 14,500 grt TSL will be built from aluminum and measure 460 x 98 ft. (140 x 29.8 m). To be built by Mitsui Engineering and Shipbuilding's Tamano works for delivery in 2005, the TSL will be propelled to a service speed of 38 knots via a pair of Rolls-Royce Kamewa VLW J235 waterjets, which will absorb 27 MW of power
Safe guard your cooling system from costly damage with Livorsi’s Raw Water Flow System The Raw Water Flow system is a new patented system that indicates your engine’s water flow volume. This system warns you of a potential problem or danger that would otherwise not be indicated by a water pressure gauge alone, thus preventing cosmetic and structural damage to expensive exhaust headers, intercoolers and cooling systems. What is Water Flow?
Atlas Copco has introduced a new small range of WEDA pumps to provide fast and efficient dewatering. In addition to the original nine pumps, the WEDA04 and WEDA08 provide drainage pumping, with the WEDA08S for sludge pumping and the WEDA04B for low suction pumping. The WEDA04 drainage pump is equipped with a 400-watt electric motor, while the WEDA08 features a 750-watt electric motor. The polyurethane semi-vortex impeller reduces the risk of clogging

The U.S. Coast Guard issued a Safety Alert stating that a chemical tanker recently suffered a tank explosion in the Gulf of Mexico near Galveston. After stripping a tank, the tankerman opened the tank top cover and an explosion ensued, injuring the tankerman and damaging the vessel. While the investigation is ongoing, the cause appears to be that the bearings in the cargo pump failed, allowing the shaft and impeller to shift and spin against the casing
Ultra Dynamics has announced the release a new waterjet model the UltraJet UJ410 -- with a 410 mm diameter impeller – which fits neatly into the middle of its UltraJet range of waterjets, providing more options between the UJ376 and UJ451. All components on the new model are plug-and-play and mounted on jet, including the oil cooler, oil pump, sensors and valves, and hydraulic steering and reverse cylinders, keeping installation for the boat builder to a minimum.
Two pairs of Hamilton HM651 jets with 25-in. impellers are being installed on two 170 x 30 ft. (51.8 x 9.1 m) hulls being built for the Candy fleet at Swift Ships Morgan City shipyard.
