Drill Riser Buoyancy Module

Drill Riser Buoyancy Modules (DRBM) 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.

Depth range

Module densities provide uplift for riser in saltwater depths up to 12,000 ft.

Syntactic foam core

Low density syntactic foam comprised of a combination of hollow composite microspheres and macrospheres to provide uplift.

Molded recesses

Design includes recesses to accommodate fastening hardware and auxiliary lines of drill risers.

Fiberglass exterior skin

Tough exterior skin provides excellent abrasion and impact resistance to avoid damage in handling and installation.
