Maintainance dredging :
Maintenance dredging consists of the removal of sedimentation to maintain the required depth of waterways, channels and ports. Maintenance dredging works are the most traditional dredging projects.
However, this type of works did eventually lead to the development of the trailing suction hopper dredger and is of vital importance to harbours.
Dragado is in process of procuring a very diverse fleet of modern trailing suction hopper dredgers, enabling it to execute maintenance dredging projects even in fairly shallow waters. The largest project so far undertaken is undoubtedly the Maintenance.
