DREDGING -
for OIL and GAS activities in Canada
Dredging is an excavation activity or operation usually carried out at least partly underwater, in shallow seas or fresh water areas with the purpose of gathering up bottom sediments and disposing of them at a different location. In Holland dredging and land reclamation has been ongoing for centuries, ever since the Frieslanders first settled there. GOD CREATED THE WORLD BUT THE DUTCH CONSTRUCTED HOLLAND

Environmental cleanup and disposal
Pollution Recovery System
Designed to remove oil and chemicals from vessels lying on the sea bed in very deep water without using divers. Currently depths of 500 meters can be obtained and greater depths down to 4000 meters are envisaged.

EXCAVATING HARDER MATERIALS
Innovation, Engineering &Development
Pipeline trenching is now possible in seabed soils with UCS values up to 30 MPa in harsh metocean conditions and environmentally sensitive areas. Hard soil is normally dredged by means of a Cutter Suction Dredger. Special drag heads (ripper drag heads) are developed for large Trailing Suction Hopper Dredgers for the dredging of harder soil.
