News: Cal Dive Riser System Deployed in Deepwater Project

Monday, November 24, 2003

Well Ops, Inc., a subsidiary of Cal Dive International, Inc. had the successful first application of the company's purpose-built, open water intervention riser system. Cal Dive's well intervention vessel, the Q4000, deployed the system in 1,042 ft. of water, where it was latched to a horizontal Cameron tree. The system includes a control umbilical, two-in. annular line, 7.375-in. flowhead and swivel.

The riser system was integral to a successful well decommissioning operation conducted for a major client in the Gulf of Mexico. The system remained at depth during through-tubing zonal and annulus abandonment operations. The tree was recovered with the system once the well had been safely plugged.
