Trelleborg Offshore Buoyancy Goes Deeper Than Ever

December 2009 Vol. 236 No. 12

The first drill riser buoyancy modules capable of withstanding nearly 5,000 psi (c. 350 bar) pressure at 11,000 feet (c. 3,350 meters) below the surface have been developed and manufactured by Trelleborg Offshore.

The new syntactic foam buoyancy modules were designed and manufactured for Transocean Inc. for use in the Indian Ocean on its latest deepwater drilling rig. The modules use buoyancy technology to withstand the extreme 11,000-foot marine environment.
