This particular cutting technique was developed as a solution for decommissioning structures where the stability of the cut structure is a main factor.

The DWCM feeds into approximately 50% of the cut on the horizontal plane, then cuts vertically for a height previously decided and finally completes the cut on the horizontal.

This allows for a jacket to be cut whilst insuring that it will not topple until it is actually pulled over, as demonstrated successfully in May 2005, when CUT-UK completed the two Rig to Reef Projects.
