The vanguard of sustainable development.
Working at the top of an industry, requires continuous innovation to maintain market leadership. DEME’s in-house Research, Development and Engineering division has some of the finest and most experienced specialists at hand to see to this. Adapting plant to the specific needs of a project, improving efficiency of existing equipment, developing new techniques, and researching and implementing new dredging vessel designs, is a permanent concern of this talented staff.
Innovation at DEME does not happen behind a drawing desk. Not only do our R&D engineers have a broad experience in the field, but they rely very much on a continuous input from crew and project managers abroad. This is a tradition within DEME companies, which goes back to the very roots of our Group.

Development of DRACULA, an acronym for “DRedging, And Cutting Using Liquid Action”, which has resulted in improved efficiencies on trailing suction hopper dredgers and cutter suction dredgers of up to 20 percent.
|
Substantial suction improvement on trailers and cutters following the use of a booster jet inserted in the suction line of the dredge pump.
|
Development of an underwater grab and drag system to excavate “glory holes” in water depths of up to 120 metres, using a combination of a very large clamshell bucket steered by a remotely operated vehicle (ROV).
|
Development of the computer controlled spreader pontoon Bayard-II, the swing- speed of which is controlled by the amount of sand and gravel that is pumped from a cutter dredger.
|
Development of the computer controlled slope trimmer Rhea, capable of working in water depths of up to minus 38 metres.
|
Development of a new and highly efficient soft soil improvement method.
|
Development of special plant for eco-dredging.
