During cyclone Gonu, a category 5 storm, which impacted the east coast of Oman in June 2007, a number of small craft harbours were severly damaged. Most of the breakwater structures were armoured with various sizes of rock protection. The Al Masaood Harbour near Dibba Al Fujeirah (north eastern UAE) suffered less damage due to the appropriate size of rocks on the breakwater. However to limit future damage due to possible increased storm activity, it was decided to armour the breakwater with CRABLOCK concrete armour units. This paper describes the development and use of CRABLOCK, which is similar to the Hexapod in shape (SPM, 2006). The results of physical model tests carried out at CSIR, in South Africa, are also presented and discussed.
