Keppel Singmarine Pte. Ltd. last week held a keel-laying ceremony for the medium-sized 6,000m³ trailing suction hopper dredger which is being built for Jan De Nul Group.
Earlier this year, JDN placed an order for six ultra-low emission TSHDs, five of which are being built at Keppel: three small 3,500m³, two medium-sized 6,000m³ and a larger vessel of 18,000m³ at the Cosco (Dalian) Shipyard in China.
According to the company, all six vessels will be diesel-electrical powered, with engines allowing optimal use of generated power but with low fuel consumption and emissions.
In addition, the vessels will be equipped with a two stage highly efficient exhaust gas filter system, resulting in emissions complying with the European Stage V regulations for inland waterway vessels.
Jan De Nul Group recently decided to name both 6,000m³ dredgers after two decommissioned vessels of the Groups fleet: Sanderus and Ortelius.
