CRP Subsea awarded a major contract to provide Distributed Buoyancy Modules (DBMs)

CRP Subsea was recently awarded a major contract to provide Distributed Buoyancy Modules (DBMs) for what is thought to be the world’s deepest-ever Flexible Riser, complementing an earlier successful delivery in 2020.

The project requires the DBMs to be stored for several years at the full ocean depth making this the deepest ever Flexible Riser DBM project. The DBMs will create a lazy wave riser configuration reducing top tension and increasing the lifetime of the field.

Steven Bray, Sales Team Manager for Buoyancy and Clamping Systems at CRP Subsea states “Our market leading 28-year track record, with over 44,000 Distributed Buoyancy Modules supplied worldwide, made us the partner of choice for this project.  We are extremely pleased to have been selected on the basis that our qualified foam and clamp systems providing a cost effective, low density proven solution capable of exceeding these depths with maintenance free service for 30 years and beyond.”

Manufacture of the DBM’s will take place in CRP Subsea’s state-of-the-art manufacturing facility in the North of England. Project engineering works will commence immediately, with installation activities scheduled for the end of 2021.

A DBM is typically used between structures and a surface vessel or platform, providing uplift generated by a two-part buoyancy element and a clamp. CRP Subsea’s unique clamping solution allows the DBMs to be securely attached at any point along the length of a rigid or flexible pipeline or cable.
