In floating production scenarios, pipelines such as flexible risers, cables, and umbilicals are often required to be held in specific geometric configurations subsea, designed to prevent damage of the system. Although numerous configurations have been developed and implemented over the years, one favoured method is to attach discrete Distributed Ballast Modules to the outside of the pipeline. The ballast load must not migrate or degrade over the design life of the product.
Distributed Ballast Modules are typically used between a subsea structure and a surface vessel or platform. The clamping solution allows the Distributed Ballast Modules to be fitted at any point along the length of the pipeline.
The two main functions of the Distributed Ballast Modules are to provide weight and damping stability to a specific location along the riser. The Ballast is generated by a two-part Ballast component. A clamp securely attaches the assembly to the desired location on the riser. The Ballast segments are assembled to mechanically lock around the clamp and are secured with circumferential straps.
To provide the project performance at every level, the Ballast system can be adjusted to operate in seawater depths from surface to 6,000 metres and beyond.
