Rolls-Royce unveils upgraded stabiliser system for ice-class ships

Incorporated in both the Aquarius and Neptune ranges of Rolls-Royce retractable stabilisers, the SAR system uses active fin control technology and advanced hydrodynamic design to ensure greater levels of roll reduction when vessels are either stationary or under way.
In the new design, the stabiliser fins can be fully retracted into the custom-designed fin box, so there are no protrusions from the hull, thus ensuring safe navigation through ice. The stabilisers have a smaller fin area and an optimised lower fin angle, leading to a reduction in drag and reduced fuel costs when under way.
Recognising that the stabilisers are likely to be used on vessels operating in environmentally sensitive areas, the company has adopted a special quad seal arrangement to minimise the risk of leakage. The stabilisers are fully compatible with a wide range of environmentally acceptable lubricants.
