HOUSTON-- Trelleborg Offshore has developed and manufactured drill riser buoyancy modules capable of withstanding nearly 5,000 psi (50 bar) pressure at 11,000 ft (3,350 m) below the surface.

The modules were designed and manufactured at the company’s Houston facility for use on Transocean’s drilling rig Dhirubhai Deepwater KG1.

The modules are constructed from a low-density composite syntactic foam and macrospheres. The foam is then encased within a durable external skin that includes Trelleborg's Ultra MIS module integrity system.

“Exploration is continually pushing back the boundaries and demanding more from technology so we are constantly striving to develop new products,” says Todd Grahn, sales manager for Trelleborg Offshore US. “The next stage of 15,000 ft (4,500 m) is already going through testing and we will be ready to supply when the need arises."
