Ardyne have performed a P&A project for a major operator on the Norwegian Continental Shelf.  Ardyne are delivering savings on this project by eliminating the need to change from a production riser to a drilling riser.  This is achieved by milling out the 10 ¾ subsea hanger to enable retrieval of 10 ¾” x 9 5/8“ csg through the production riser, and resulted in a saving of 4-5 days on each well.
