The new Damen CSD250 dredger delivered to Nigeria has already started on making its own pond, eventually to become a canal. The CSD250 has started creating a canal, which will flow eventually in the Benin River, and through to the Atlantic Ocean. The canal is initiated by Ossiomo Investments, the owner of the industrial park. On the park a fertilizer plant will be constructed, amongst other petrochemical plants. A canal is to be dredged and an inland port  constructed to facilitate marine transport.

A Nigerian customer added its ninth Damen dredger to its fleet. The Cutter Suction Dredger type CSD500 was chosen due to the availability of Damen Field Services in Nigeria, the builder said, adding that the local presence was even more practical in view of the challenging assembly conditions. For Damen’s Service Hub Nigeria this job is one of the first successes. Damen Shipyards Group usually has a spares-stock available in Nigeria for standard dredgers such as the CSD500.
