Bridges and tunnels

Peter Madsen Marine Contractors have been involved in the marine activities related to construction of bridges and tunnels for decades.

Our services include pre-dredging and installation of stone beds for bridge piers, ballasting of foundations, installation of scour protection, construction of collision protection as well as a full multibeam survey package.

Our fleet of six vessels are equipped with either backhoe hydraulic excavators or wire excavators with grabs, all suitable for dredging activities or placing of rock materials from gravel size up to 9 tonne individual blocks.

The vessels have fixed holds for transportation of materials and can self-load. The PDS2000 guidance system enables us to accurately dredge or place rock.
