"Our innovative technologies fit perfectly with the ambitions of Great Lakes, where technical innovation is one of the driving forces behind the success of their dredging activities.”

"Our proven systems for suction tube monitoring and hopper loading deliver maximum added value to our customers," said Johan van Rikxoort, solutions manager at Alewijnse. The systems were installed on board the Liberty Island, a large trailing suction hopper dredger, which was deployed immediately after completion for a beach replenishment project in Buxton, N.C. Electrical systems integrator Alewijnse has delivered its newest dredge control solutions to Great Lakes Dredge & Dock Co, the largest provider of dredging services in the U.S.
