Jan De Nul orders 6,000 cu.m hopper dredge

MAY 23, 2017 — Belgium’s Jan De Nul Group has signed a contract with shipbuilder Keppel Singmarine Pte.Ltd. for the construction of a 6,000 cu.m trailing suction hopper dredge (TSHD), bringing its current newbuilding order at the shipyard to four hopper dredges. It has an option for a fifth.

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 cu.m TSHDs ordered in July of last year and currently being constructed by Keppel Singmarine (see earlier story).

“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.”
