Up to the present time open sea sand delivery operations have been carried out by trailing suction hopper dredges and stationary suction dredges under favorable weather and wave conditions. When working in exposed areas under unfavorable conditions, these types of dredges have a low operational efficiency. A new type of dredge has been developed which provides a solution to the problems attendant to stationary dredging operations in open sea and which has a semi-submersible hull. This paper deals with a design developed for a Semi-Submersible Dredge (SSD) destined for operations in southern areas of the North Sea, and in which areas it can operate for 95% of the year. The SSD offers the opportunity to supply sand to coastal areas from the open sea under circumstances in which conventional dredging equipment is unable to operate.
