Drill Riser Buoyancy Module

Product Sheet

Drill Riser Buoyancy Module

Drill Riser Buoyancy Modules are fitted along the length of the riser to reduce the weight of a drilling riser to a manageable level. Reducing this weight is critical in expanding exploration and resource recovery for ultra-deepwater fields.

Drill Riser Buoyancy Modules densities provide uplift for a riser in saltwater depths up to 12,000 ft. A low-density syntactic foam core comprised of a combination of hollow composite microspheres and macrospheres provide uplift.

Designs include recesses to accommodate the fastening hardware and auxiliary lines of drill risers, and a tough exterior skin provides excellent abrasion and impact resistance to avoid damage during handling and installation.
