The Pevensey frontage has historically suffered from coastal erosion and flooding resulting from storm wave attack. In the late 1990s it was realised that an innovative form of contract was needed to provide management capable of minimising this problem. This led to the formation of PCDL, a consortium of Westminster Dredging, Dean & Dyball, Mackley Construction and Mouchel. This team provides all the skills necessary to manage the 9km shingle embankment that form Pevensey Bay’s sea defences.
Boskalis Westminster (previously Westminster Dredging Company) annually provides 20 - 25,000m³ of shingle via the trailing suction hopper dredger ‘Sospan Dau’, delivering 800-900m³ per tide. With a draft of only 3.6m fully laden, the vessel is able to come close inshore and place aggregate onto the beach just below the high water mark. This type of operation negates the requirement for truck delivery via the road network, particularly important in areas such as Pevensey where truck convoys have historically caused much local disruption.
