Abstract


The title of the paper contains two important key words - CONSTRUCTION and ISLAND. The techniques for safe and economical construction of an island breakwater located some distance from the shore in exposed waters are radically different from the techniques required for conventional breakwaters with one end attached to the land. The differences in construction technique are so profound as to change the preferred basic design selection from rubble mound to caissons. The paper discusses:- 1. The circumstances in which island breakwaters will become increasingly necessary for unloading of bulk ships. 2. Reasons why prefabricated caisson breakwaters are preferable for construction in an offshore situation. 3. The economy to be gained by using the caissons as the structural support for ship unloading machinery. 4. A consequent necessity to develop a caisson breakwater configuration with adequate design criteria to ensure total safety of the equipment supported on it. 5. A research program aimed at deriving these criteria.
