FIN STABILIZATION OF SHIPS--PROBLEMS OF SPECIFICATION AND PERFORMANCE COMPARISON

After describing the advantages of roll stabilisation, with particular reference to fin stabilisers, the Author (of Brown Bros. & Co. Ltd) discusses the important parameters that affect stabiliser performance, with the aim of assisting those ship owners and builders who may have difficulty in preparing a suitable specification and in making comparisons between the claims of different fin-stabiliser manufacturers. These parameters are discussed under the headings: Components of the System; Roll Reduction; Waveslope Capacity--Definition; Waveslope Capacity--Required Magnitude; Stabiliser Design Speed. The points that should be considered in order to ensure a successful and economic fin-stabiliser installation include (i) specifying the ship's seakeeping requirements at an early design stage, in consultation with the stabiliser manufacturer; (ii) ensuring that the metacentric height is optimised for both stability and seakeeping requirements; (III) determining the required waveslope capacity; (IV) determining the speed at which the waveslope capacity should be achieved, and whether the capacity should also be specified for an additional, slower speed; and (v) noting that the stabiliser will be selected from a standard range, and avoiding too rigid a specification that might force the manufacturer to offer a larger size than is necessary.
