Stabilisation At Rest (SAR) Ice Class

Using retractable fins for Ice Class vessels. The fin fully retracts into the fin box when not in use using an innovative five sided swept fin design.

This design of stabilisers builds on the success of the Stabilisation At Rest design introduced in 2006 for the Aquarius range and subsequent implementation for the Neptune range. This fin stabiliser allows Ice Class and Polar Class vessels to be fitted with Stabilisation at Rest. This new design, when fully housed into the customised fin box, results in no protrusions from the hull frm and gives the operator peace of mind and allows safe navigation through ice waters.

The new reduced fin area and optimised lower fin angle, whilst meeting the performance requirements, results in reduced dynamic drag when deployed underway leading to lower fuel costs. The stabiliser fin also incorporates the tested optimised trailing edge designed to eliminate vibration and noise.

With the environment in mind, the stabiliser machinery is fully compatible with an extensive list of EAL’s that are available worldwide and incorporate a quad seal arrangement for additional integrity of sealing.
