Abstract : Investigations into the flexibility of divergent systems for providing a Multi-Purpose Harbour Unit led to the conclusion that caisson-type units are probably most adequate for breakwater purposes and can, moreover, effectively be adapted for the alternative formation of piers. Apart from tests for determining the attenuation performance, liability to scour, and specific problems with respect to transport and handling, considerable attention was paid to the forces exerted by incident waves and the attendant response of the structure. An amplification of the customary criteria wave conditions with experiments to establish the effect of dynamic and quasi-static forces inherent to irregular wind generated waves necessitated a statistical processing of the records. The various results have been incorporated in the preliminary design of three different caisson units, of which the ''twin pontoon'' most likely offers the best prospects for practical application.
