Siemens has successfully concluded the 1st phase of its subsea power grid shallow water test in Trondheim, Norway.
Siemens, in collaboration with industry partners Chevron, Equinor, ExxonMobil, and Eni Norge, is in the final stages of a program to develop a barrier-breaking system that will become the world’s 1st subsea power grid designed for distribution of medium voltage power using pressure compensated technology.
«There will be more subsea compressors, pumps, processing plants, and in the future entire production facilities placed on the seabed, all of which require power,» said Frode Tobiassen, head of subsea at Siemens. «This development is what we are preparing for with the subsea power grid.»
The underwater power grid consists of a subsea transformer, subsea switchgear, subsea variable speed drive, subsea wet mate connectors, and a highly reliable remote control and monitoring system that includes cloud-based user dashboards and data analytics.
Subsea power distribution systems will play a major role in the future of subsea field development projects. The system is an enabling technology for subsea processing with multiple seabed power consumers. The system is ideally suited to support enhanced recovery in subsea brownfield projects and tie-back fields, benefitting from single- or multiphase boosting to increase oil recovery.
