In the last week of 2011, Damen Dredging Equipment delivered the CSD500 “Conchas”. Its owner, the UK based company Marina and Ports Services, ordered the dredger mid October 2011. In a mere 2 months the standard dredger was taken from Damen’s stock and has been fitted out with a large number of customised options (Fig. 1). The standard CSD500 has a maximum dredging depth of 14 m. A separate wedge piece was added to enable the dredger to work at a minimum dredging depth of 1.5 m (Fig. 2). Other functional additions are, for example, a spud carriage pontoon enhancing the efficiency of the dredgers movements due to a cylinder stroke of 4 m. Moreover anchor booms of 14 m length were added. Other distinctive features are day accommodation (including a galley, a sanitary space and a day room); a 35 kVA harbour generator set, a 4 t jib crane facilitating servicing the dredger’s engine room area, a non-return valve in the discharge piping, a stern swivel for a smooth connection to the floating pipe line, and supplementary fuel, fresh water and sewage tanks in the fore pontoons. At the spacious operating cabin a full communication package is available, plus the required dredge pump performance monitoring instrumentation, dredge pack position visualisation versus chart data and navigation lights.
