Collaboration Leads to First DBMs for Installation by ROVs
To meet customer demands, Trelleborg’s offshore operation collaborated with SubC Partner to design, manufacture and test a Distributed Buoyancy Module (DBM) for installation by a Remotely Operated Vehicle (ROV) on to an FPSO’s 12 inch production riser in a steep wave configuration. By having an ROV installable DBM, Trelleborg and SubC Partner were able to successfully execute a world first offshore project, which succeeded in replacing buoyancy modules on a live riser, without shutting oil production. In floating production scenarios, pipelines such as flexible risers, cables and
