Topside Cutting Topside Cutting

Topside

CUT Group also has experience in cutting in air. In 2016 we successfully completed the completed the cutting scope on the Brent Delta Topside Separation Project.

The scope of work included the separation of the cellar deck from the GBS legs. Three legs connect the subsea storage cells to the cellar deck and topsides. The total cutting area of the three legs was 46sqm of concrete with 235 bolts and Neoprene were cut.

Prior to cutting, core drilling was carried out using a core drilling rig with electric core drilling motor for the installation of pipes and cables, anchoring bolts and load carrying devices. The DWC System selected for the cutting operation operates on the principal that the wire is passed round the target and field joined. The resulting looped wire is then run at a planned speed and pulled through the target from the inside of the leg.
