Distributed subsea floating buoyancy modules help mitigate the buckling by reducing the self-weight of the flowline as well as the friction against the seabed. With the buoyancy modules in place, a span of lower resistance is established along the flowline, enabling the buckling to occur in known, controlled and more predictable conditions.

Riser & umbilical buoyancy advantages

•Light weight 

•Easy to handle

•On the surface or in subsea

•Flowline buckling mitigation

•High quality, consistent modules 

•In low water absorption and compression

•An integral or secondary clamp can be custom

•Provide maximum impact and abrasion protection

Umbilical buoyancys generally consist of an internal clamping system and syntactic foam buoyancy elements. The buoyancy elements are supplied in two halves incorporating a moulded internal recess that is configured to transfer the forces from the buoyancy to the clamp and subsequently the flexible. This recess also accommodates bending of the riser during deployment and service. The internal clamping system is fixed to the pipe and the two half modules are fastened around the clamp.

Subsea cable floats normally involve an offshore floating production facility or terminal connected to another floating facility or fixed structure.

Surface projects provide the required project performance, the buoyancy system can be adjusted to operate in seawater depths from surface to 6,000 metres and beyond

Philson has been at the forefront of significant R&D efforts to meet this challenge and has developed a number of solutions for deep and ultra-deepwater environments.All modules are custom-designed to each application by taking into consideration the designed uplift, umbilical specifications, and deployment strategy.
