Having subsea power distribution could also support seabed mining operations and the increasing move to autonomous marine systems, which would need power. Integrating batteries and offshore wind would need subsea control systems, and this is something ABB is also working on.Photos from ABBSiemens close to qualifiedAnother JIP was run by Siemens Energy to deliver 6 MVA of power over 200km and distribute it locally, is
