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.
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.
