A Nigerian customer has added his 9th Damen dredger to his fleet. The cutter suction dredger, type CSD500 was chosen due to the excellent availability of Damen Field Service in Nigeria. The Damen Shipyards Group has a spares stock available in Nigeria for standard dredgers such as the CSD500. With the cutter suction dredger maintenance contracts are offered to keep the dredgers in tip top condition.
The most challenging side of this job has been the dredger assembly (Fig.). It was planned at a scrap yard on a swampy side branch of a river. The local conditions were worsened by the rainy season. The locally sourced cranes of 250 and 500 tonnes were stuck in the mud more than once. When the cranes arrived on the assembly site, the ground had to be strengthened. Moreover the dredger had to be hoisted 25 m from the river bank as conditions were too swampy right next to the bank. The Damen cutter suction dredger is a CSD500, dredging at max 14 m and pumping some 4000 m3/h of mixture. The dredger is currently working on a land reclamation job near Warri.
