Distributed buoyancy module
Buoyancy clamps
Buoyancy clamps secure buoyancy modules to risers, pipelines, cables and umbilicals, maintaining module position throughout installation and operation while accommodating demanding offshore loads and environmental conditions.
Item link
Integral buoyancy module
Integral buoyancy modules combine clamp and buoyancy elements into one unit, removing the need for separate internal clamp assemblies.
Item link
Flowline buckling mitigation
Flowline buckling mitigation buoyancy modules promote controlled flowline movement by adding buoyancy in discrete locations. This reduces compression forces, bending moments and shear forces, mitigating buckling while maintaining flowline integrity throughout thermal cycling and subsea operation.

Midwater arches
Midwater arches support flexible risers, umbilicals and cables as they rise from the seabed to the surface, maintaining position, depth and proximity.

Distributed buoyancy module

Distributed buoyancy for subsea riser stability

Distributed buoyancy modules are used in floating production scenarios to stabilise risers, cables and umbilicals in specific configurations, preventing damage and maintaining project specific geometry throughout operational life.

Benefits

Reduce loads with controlled buoyancy systems

Distributed buoyancy modules provide uplift and maintain location along risers and pipelines. The buoyant load is securely attached using clamp and strap systems, ensuring configuration control, preventing migration and supporting reliable performance across deepwater subsea and floating production environments.

Load reduction
Reduces top tension loads by providing controlled uplift along risers and pipelines, improving structural performance and reducing stress in floating production and deepwater subsea environments.
Configuration control
Maintain project specific riser configuration by securely positioning buoyancy modules along the pipeline, ensuring stability and preventing unwanted movement or deformation during offshore operations.
Proven track record
Extensive subsea track record supported by industry qualified materials and geometry, ensuring reliable performance and compliance across demanding offshore buoyancy applications and deepwater environments.
