New Technology Launch: DeepOcean, in collaboration with TotalEnergies, Equinor, Aker BP, Tenaris, and LS Cable & System, has introduced FlowHeat, a subsea flowline heating technology designed to reduce manufacturing and installation costs by up to 35% and carbon emissions by 30%.
Operational Efficiency: FlowHeat addresses challenges in cold, deep-water environments by allowing cable installation after pipeline laying, effective for distances up to 30km (potentially 50km) and depths of 3,000m, while utilizing smaller remotely operated vehicles for installation.
Market Potential: The technology is expected to have a significant market presence, particularly on the Norwegian Continental Shelf and in other deep-water regions like Brazil, the US, and Africa, with over 300 potential electric heating projects anticipated by 2030.
Support and Validation: The project is backed by the Research Council of Norway for pilot testing, with industry leaders expressing enthusiasm for the technology's potential to unlock longer tiebacks and access remote reserves.
