Buoyancy modules endure 11,000ft ocean environment
A
Trelleborg Industrial product story
Edited by the Engineeringtalk editorial team
Oct 14, 2009
Trelleborg Offshore has developed drill riser buoyancy modules capable of withstanding nearly 5,000psi (350bar) pressure at 11,000ft (3,350m) below the surface for deep-water exploration.
The new syntactic foam buoyancy modules were designed and manufactured for Transocean for use in the Indian Ocean on its latest deepwater drilling rig, the Dhirubhai Deepwater KG1.
Manufactured at the newly expanded Trelleborg facility in Houston, Texas, the modules use buoyancy technology developed during years of research and testing to ensure that they can withstand the 11,000ft marine environment.
The drill riser buoyancy modules are constructed from a low-density composite syntactic foam and macrospheres.
The composite syntactic foam is then encased within a durable external skin, which includes Trelleborg's Ultra MIS module integrity system.
