OFFSHORE BREAKWATER FOR THE SER6IPE MARINE TERMINAL, BRAZIL

Malcolm Murray, Otavio J. Sayao

Abstract


This paper describes the development of an alternative design for the offshore breakwater of the Sergipe Marine Terminal (Terminal Portuario de Sergipe, TPS), in northeast Brazil. Earlier alternative designs for the breakwater are presented and the chosen solution, a berm breakwater design, is described. Details of the hydraulic model testing carried out during the designing stages are given and the construction methods are explained together with a brief overview of construction controls and organization. In order to accommodate the unfavourable subsoil conditions which were found to be worse than initially expected, a redesign of the offshore breakwater was carried out. The new redesign is presently under construction. The TPS breakwater is the first berm type structure to be constructed in Brazil and one of the few in the world to be constructed over a soft marine clay layer.
