What's Happening?
DeepOcean, in collaboration with TotalEnergies, Equinor, Aker BP, Tenaris, and LS Cable & System, has introduced FlowHeat, a subsea flowline heating system aimed at improving flow assurance and reducing emissions in deepwater developments. The system,
part of a joint industry project led by DeepOcean, features a patented heating solution that allows power cables to be installed post-pipeline lay or integrated within reeled pipelines. This innovation promises to cut manufacturing and installation costs by up to 35% and reduce carbon emissions by 30%, while enhancing operational efficiency and extending tieback distances. The FlowHeat system addresses challenges such as wax and hydrate formation in long-distance flowlines, offering simplified installation, reduced topside complexity, and real-time monitoring capabilities.
Why It's Important?
The introduction of FlowHeat represents a significant advancement in subsea pipeline technology, offering substantial cost savings and environmental benefits. By reducing topside weight and power consumption, the system enhances long-term reliability and operational efficiency. The technology is capable of operating over distances up to 30 km, potentially extending to 50 km, in water depths reaching 3,000 meters. This flexibility allows deployment using smaller remotely operated vehicles, improving logistics and reducing vessel time. The global potential for electric heating solutions is expanding, with over 300 potential projects identified worldwide by 2030. The system's cost efficiency and environmental advantages are expected to drive demand in regions such as the Norwegian Continental Shelf, Brazil, the United States, and West Africa.
What's Next?
The next phase of the FlowHeat project will involve full-scale qualification testing, as stated by Florent Boemare, TotalEnergies’ Offshore Solutions and Technology Research Manager. The consortium anticipates that this technology will unlock longer tiebacks and access to remote reserves. Successful small-scale and thermal trials have already demonstrated reliable cable installation, high electrical efficiency, and low power demand. The project is supported by the Research Council of Norway, which has provided funding for pilot testing under real operating conditions.
Beyond the Headlines
The FlowHeat system not only offers immediate operational benefits but also contributes to the broader industry trend towards sustainable and efficient energy solutions. By reducing emissions and improving efficiency, the technology aligns with global efforts to transition to cleaner energy practices. The collaboration among industry leaders highlights the importance of joint efforts in advancing technological innovations that address environmental challenges.
