DEME orders dual-fuel hopper dredgers

LNG Industry,

DEME has ordered two new trailing suction hopper dredgers, which will be equipped with dual-fuel engines and LNG tanks.

Built to a ‘green’ design, the two vessels will have a ‘Green Passport’ and a ‘Clean Design’ notation. The dual-fuel capability will ensure compliance with international emission requirements within the sulfur emission control areas (SECA).

In view of the dual-fuel technology, the ships will be manned with trained high-tech personnel. Both trailing suction hopper dredgers will be built by Dutch shipyard Royal IHC, and will be operational before the end of 2016.

Vessel specifications

The first vessel will be a new generation trailing suction hopper dredger in the ‘Antigoon class' with a hopper volume of approximately 8000 m3 and a total length of 104 m. It has a maximum draught of 7.5 m and a powerful pump for pumping dredging materials ashore.

The second vessel will be a new generation trailing suction hopper dredger to replace the 'Orwell class', with a hopper volume of 3000 (3500) m3. Its design ensures optimised maintenance dredging works in shallow waters, with primary assets including a very limited maximum draught of 5.00 (5.80) m, excellent carrying capacity and a length of 77 m.
