Jan De Nul Group to build the fourth Trailing Suction Hopper Dredger for Keppel Singmarine Pte.Ltd.

Jan De Nul Group orders another Hopper Dredger

LUZEMBOURG, 26-May-2017 — /EuropaWire/ — Jan De Nul Group signed a contract with Keppel Singmarine Pte.Ltd. for the construction of a 6,000 m3 Trailing Suction Hopper Dredger (‘TSHD’), bringing the current newbuilding order at the shipyard to four hoppers. An option for a fifth hopper dredger has been provided in the contract.

The vessel is in diesel-electric execution, allowing optimal use of the generated power and lowering fuel oil consumption and emissions. In addition, an exhaust gas treatment system is installed, and pollutant emissions will comply with the future EU Stage V regulations for inland waterway vessels. The system is similar to the one installed on the three 3,500 m3 TSHDs ordered in July of last year and currently being constructed by Keppel Singmarine.

“We are glad to be leading the way in meeting the most stringent global emission limits with the world’s first EU Stage V dredgers, which will be highly fuel-efficient, versatile and productive,” says Robby De Backer, New Building Director at Jan De Nul Group. “Their use will enable execution of dredging projects with the lowest level of pollutant emissions, even better than that of LNG powered vessels using dual-fuel engines.”
