The 54m² rudder is provided with Asymmetric Rudder Technology (ART™). ART™ is a special rudder design that has been developed to improve propeller flow. A special layout modifies the profile above and below the centreline of the propeller in such a way that effects of the rotation of the propeller slipstream are countered. This expands the cavitation-free rudder angle and reduces drag, increasing speed or improving fuel consumption. Reduced rudder cavitation also gives an extended life span to rudders and shaft bearing systems. Low vibration and noise levels are an additional bonus.
Rotary Vane steering gear for largest vessel Jaya Shipbuilding and Engineering
In Singapore, Jaya Shipbuilding and Engineering delivered its largest and most advanced vessel built so far. The 85 metre Jaya Supreme, to be renamed Atlantic Kestrel, was delivered to its Canadian owners, Atlantic Towing Limited, at the end of November. The Jaya Supreme is one of the most sophisticated offshore support vessels ever built in Singapore, and has been equipped with Van der Velden™ COMMANDER rotary vane steering gear. A key benefit of the rotary vane steering gear is that the rudder angles of up to 2 x 65º give greater flexibility when choosing the design and type of the rudders. Enhanced manoeuvrability and increased control in harbours are the result.
