The centre'spremium hydrodynamic environmentboosts expertise, especially with itstwo cavitation tunnels.

2 These allow usto study the complex interactionbetween rudders, propellers and hullsin depth, leading to solutions thatmeet customer demand for reliability,cost-efficiency and optimalperformance tailored to meet theneeds of individual , credit for these productsmust be given to our customers. Theyhave shared their hard-earnedexperience and helped refine productsto excellence by working closely withour marine engineers. Closecollaboration with customers on aproject is therefore a key elementwithin the Rolls-Royce range a single source suppliersimplifies product and systemintegration on board.

4 Our design principles are always focusedon the future operation and service needs ofmodern, high-tech vessels which demand the bestproducts available on the vast expertise in marine technology and longtraditions of working closely with customersenables us to supply a full range of motion controlproducts and systems. Internationally acclaimedproducts such as Tenfjord and Frydenb steeringgear, Ulstein Hinze rudders, Brown Brothers finstabilisers and Intering stabilisation of these products have operational lives of25 years or more. We are therefore committed toprovide services that ensure cost efficient andreliable operation beyond a truly international presence with fullyqualified local service engineers and technicians,Rolls-Royce provides an unequalled global marinecapability.

6 The products aredesigned with the totality of actuator,power pack, steering control andalarm system in mind. Due to a widerange of demands, great care has beentaken from material selection throughconstruction in order to meet thestrictest quality Tenfjord and Frydenb series of rotary vane steering gearshave been manufactured for morethan 50 years, with more than 25 000machines delivered. The principle of arotary vane gives more flexibilitywhen choosing the design and typesof rudder, thanks to the rudder anglesof up to 2 x 70 . Rotary vane steeringgear does make navigation throughnarrow straits safer, because of thevessels' increased manoeuvrabilityand improved control when rotary vane principle also ensuresa constant torque throughout thesteering sequence, providing the gearwith maximum power output.

7 Theunique technical solutions ensure verylow noise and vibration compact and simple designreduces weight and secures fast andeasy installation of the steering actuators are mounted directly onthe rudder stock, without necessaryuse of keys or keyways, facilitatingeasier assembly and dismantling ofthe rudder stock. The rudder torque istransmitted by hydraulic coupling orby expansion rings (for the smallestmachines). The Brown Brothers rotaryvane steering gear range is designedfor naval applications and meets thehighest standards for noise, shockand rotary vane steering gearTypicalapplications:Suitable for vessels such as.

Thesteering gear is designed withintegrated frequency controlledpumps. The pump utilises a reversiblehydraulic pump motor together witha frequency converter for changingthe speed and the direction of thepump. The design gives smoothstarting and stopping of the steeringgear, and enables a precise analoguecontrol system.
