Riser and umbilical buoyancy

What is riser and umbilical buoyancy?
- Riser and umbilical buoyancy uses buoyant modules attached to subsea risers, pipes or umbilicals to provide controlled uplift. This helps support the system, manage submerged weight and maintain the required subsea configuration.
What products are included in the range?
- The range includes distributed buoyancy modules, integral buoyancy modules, umbilical buoyancy, Linksyn and distributed ballast modules. Different systems provide buoyancy and support for specific riser and umbilical applications.
What are distributed buoyancy modules used for?
- Distributed buoyancy Modules are attached at points along a riser, cable or umbilical to provide controlled uplift. They can be configured to provide the required buoyancy and positioned to achieve the desired system configuration.
What are integral buoyancy modules?
- Integral buoyancy modules combine buoyancy and clamping functions into a single unit. They can be attached directly to flexible and steel lazy-wave risers, cables, umbilicals, flowlines, spools and jumpers.
What is umbilical buoyancy used for?
- Umbilical buoyancy is designed to keep the required length of an umbilical buoyant underwater. It can also be used for certain cable and hose applications where the diameter does not exceed 90 mm.
How does buoyancy help manage riser and umbilical loads?
- Providing uplift reduces the submerged weight of the riser, pipe or umbilical, helping manage tension and other loads within the system. The buoyancy can also be distributed to achieve the required configuration.
Can buoyancy systems be designed for specific project requirements?
- Yes. Systems can be configured around riser, pipe or umbilical dimensions, required uplift, operating depth, loads and subsea configuration. This allows the buoyancy solution to be matched to the requirements of each application.

Controlled uplift and support

Distributed buoyancy provides uplift along risers, pipes and umbilicals, helping manage submerged weight and support the required configuration throughout the subsea system.

Maintain the required configuration

Buoyancy modules can be positioned along the riser, pipe or umbilical to provide controlled support, helping maintain the desired geometry and manage loads in dynamic applications.

Designed for efficient installation

Solutions are engineered with installation and handling in mind.
