Cal Dive and FMC Announce Intervention Riser

02 March 2001

Cal Dive International, Inc. and the Energy Systems business of FMC Corporation have entered into an agreement to develop and jointly fund a new intervention riser system that will be rated to operate in water depths to 10,000 feet. It will also be the first in the industry rated for working pressures up to 15,000 psi. The riser system, to be deployed from Cal Dive's newbuild Q4000, will be able to intervene in the horizontal and vertical subsea trees of all manufacturers. Using a composite reelable 2 inch flexipipe, the riser system allows for the circulation of fluids, flow testing and hydrate remediation of subsea wells. The riser's slim bore also allows it to be handled easier and run much faster than a conventional marine riser system. For example, the new system can be latched onto a subsea tree within six hours of arriving on station. http://www.caldive.com
