Seawork exhibitor Humphree will be introducing a range of larger fin stabilisers to meet the requirements of larger vessels writes Dag Pike.

Swedish company Humphree has found an expanding market for its fin stabilisers that were developed from experience with interceptors. The range of fin stabilisers was developed to take advantage of the fast-acting electric servo motors that the company had developed to operate their interceptors. The speed of response of the motor is a vital element in any automatic stabilisation systems and Humphree quotes a response time of 0.7 seconds for their servo motors.

Fin stabilisers are a relatively new area of activity for the company and they have found a ready market for their products, partly spurred on by the effectiveness of the stabilisers and partly because of the very simple installation. The operating motors are located directly onto the end of the main shaft and by operating on the vessel’s 24 volt electrical system there is no requirement for complicated hydraulic pumps and piping.

Currently the range of stabiliser fins available from Humphree extends to 1 sq.metre and for larger vessels the fins can be doubled up. The new fins planned to be introduced to the market in the next few months will be sized to meet the requirements of larger vessels and in the workboat sector one of the main applications is likely to be for survey and diving vessels which require a stable platform for their operations. The fins can operate to stabilise the vessel when underway as well as when stopped or operating at slow speed.

One of the advantages of the Humphree stabilisers is that the design of the fin has been developed so that its shape can be quickly modified so that it can be adapted to fit closely to the hull shape. The fins can also be fitted to catamaran hulls, located inside the tunnel so that they provide stability both against pitching and rolling and they can also be programmed to operate in conjunction with the Humphree interceptors, an installation that can meet the requirements of transfer catamarans.

Humphree is now part of the Volvo Penta Group.
