Keys to the new propeller sleeve, which was officially launched last fall, are precision manufacturing and a cylindrical bore in the propeller.

The Hamilton HM Series waterjet propulsion system is a range of units designed for the efficient propulsion of a wide range of work and patrol craft and fast ferries typically in the 66- to 197-foot range. Suitable for power inputs up to 3,000 kW per units, HM Series jets would nor- mally be driven via a reduction gear- box.

A new 56-ton Royal Malaysian

Customs patrol craft outfitted with twin model HM571 jets recently achieved a maximum continuous speed of 32 knots during trials, ver- sus a 28-knot contract design speed.

Other HM Series jet applications include crew boats for the Malay- sian oil fields, a 59-foot pilot boat for the Dutch Pilots Association, patrol craft for North Africa and loiter/ boost propulsion application in new

Hong Kong Marine Police patrol craft. It was announced also that the HM Series was chosen for six

Caterpillar-powered marine police patrol craft being built at Western

Australia shipyard, and four MTU- powered Inshore patrol vessels, also being built at Western Australia.

The new HS Series of multi-stage waterjets are designed specifically to operate in the 40- to 65-knot speed range, and are proving to be a pri- mary choice option for designers of extra high-speed craft, the manu- facturer reports.

Servogear A/S of Norway, founded in 1973, has delivered approximately 900 gearboxes and propeller sys- tems, 500 of which have been in- stalled in high-speed crafts, both twin and monohull. Today,

Servogear Propulsion System sup- plies a wide variety of propulsion- related equipment, including reduc- tion gearboxes, controllable-pitch propellers, effect rudders, and more.

The systems cover an engine range of 300 to 3,000 kW and speed up to 50 knots.

The company's latest gearbox, type HD 250, is designed for high- speed craft and is available in H-

Drive, U-Drive and Twin-input/

Single-output versions. Gearwheels are crafted of high quality steel, de- signed for maximum safety and mini- mum noise. The unit is also equipped with a built-in hydraulic operated clutch and servo system to actuate the propeller pitch.

Ulstein International has achieved an important break- through into the French market. The

Norwegian Group is supplying pro- pellers, shafting and thrusters for the Dreamward and Windward

Kloster Cruise Line (KCL) vessels being built at Chantiers de 1'Atlantique, and a further signifi- cant first is the contract to supply bowthrusters for six Lafayette frig- ates being built for the French Navy.

The cruise ship contract contin- ues a long-standing Ulstein rela- tionship with KCL having previously supplied stern gear to the Royal

Viking Sun and Royal Viking Star built in Finland.

It is, however, Ulstein's first pen- etration of the Atlantique yard, made even more notable by the additional

July, 1993 supply of Ulstein Bergen diesel en- gines for auxiliary power.

The supply of bowthrusters to the

French Naval yard of DCN Lorient is also significant. In addition to the export success in the French market warships do not normally fit thrust- ers. The Ulstein's Liaaen factory is to supply a 90TV-type thruster, rated at 310 kW and specially approved to comply with Naval shock-load speci- fications, for each of the six

Lafayette-class light frigates being built. Each thruster has a diameter of 1,280 mm and will be driven at a speed of 388 rpm by an ABB electric motor through a 3.64:1 reduction gear. The first vessel in the series,

F710 Lafayette, was floated out at

DCN Lorient Naval Dockyard in

June 1992 and is currently undergo- ing sea trials.
