Three Keppel Dredgers for Jan De Nul

Keppel Offshore & Marine Ltd (Keppel O&M)'s wholly owned subsidiary Keppel Singmarine Pte Ltd (Keppel Singmarine) has secured contracts from Jan De Nul Group to build three Trailing Suction Hopper Dredgers (TSHDs). The TSHDs are worth about S$100 million in total. The first two dredgers are expected to be completed in 2H 2018 while construction of the third dredger will require a notice within six months from Jan De Nul to exercise the option for the dredger. To be built to Jan De Nul's design, the dredgers will be able to dredge to a maximum depth of 27.6m, and have a hopper capacity of 3,500 m3. The two dredgers will be built to the requirements of classification society, Bureau Veritas, in Keppel Nantong Shipyard, a subsidiary of Keppel O&M. Mr Abu Bakar, Managing Director of Keppel Singmarine, said, "We are pleased to receive these new contracts from long-standing customer Jan De Nul. Across the group, we have undertaken a number of newbuild dredger projects as well as repairs for customers such as Jan De Nul. We are always on the lookout to add value to our customers and markets, and this project is a natural extension of Keppel Singmarine's strong track record and expertise in specialised vessels. This is also in line with our efforts to deepen our presence in non-oil and gas markets where we can leverage our capabilities."

A Nigerian customer has 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 standardly has a spares-stock available in Nigeria for standard dredgers such as the CSD500

Damen Ships Modular Dredger to the Andes

Reservoirs are notoriously tricky to maintain: from the surrounding area plenty of sand and silt is brought in by the river and the material deposits at the dam. As reservoirs are usually rather deep, dredging can be quite a challenge. For the Tablachaca dam in Peru another challenge was added; the location high up in the Andes required a modular dredger due to transport restrictions. The DOP Dredger proved to be the perfect solution, according to its builder.
