Abstract

Tropical cyclones propagating in the sea hit offshore objects to get diffracted around it. The highly valuable structures such as oil drilling and storage facilities, harbours islands, breakwaters, etc are planned and constructed without resorting to detailed design involving wave diffraction which contributes to 60−70 percent of loading. This paper presents a hybrid numerical method to solve the mathematical wave diffraction problem around offshore objects, large or small. A very large planned island has been investigated by a developed model, SUBRATA/ISLAND HARBOUR. The results have been validated.
