Segmental post-tensioned dolphin at Tagrin Point

The nature and extent of resource constraints on projects in developing countries are described in the context of the construction of the dolphin at Tagrin Point in Sierra Leone, West Africa. The interplay between what is possible and what is feasible given the constrained resources is considered in terms of various design alternatives. A new type of ship breasting structure evolving from the construction constraints proves to be functional and promising. The segmental, post-tensioned dolphin not only meets the structural and functional requirements but, in making use of appropriate modern technologies, resolved the constructional problems on this project and in so doing, opens up a new field in the design and construction of berthing facilities, with the possibility of changing many concepts and previous constraints.
