As regular maintenance and relocation of sediment deposits are highly expensive, Port authorities seek more efficient solutions for reducing the costs and CO2 emissions of maintenance dredging.

WID has been proven to be a cheaper solution by leaving the sediment in place, eliminating substantial costs for relocation of the dredged sediment.

Managing risks: how to select the appropriate dredging contract

Contracts for dredging and offshore works are diverse. Moreover, increasing financial and/or managerial constraints require contracting parties to change the apportionment of commercial risk.
