Meanwhile, others have been focusing on subsea power for underwater vehicles. Independent North Sea operator Chrys- aor, for example, is working with wave energy ? rm Mocean

Eelume and Kongsberg Maritime have also formed to supply subsea power for resident AUVs or subsea tiebacks. a collaborative partnership with Triumph Subsea

The project, supported by the Oil and Gas Technology Cen-

Services to support its and its underwater garage tre, will look to use Mocean Energy’s Blue Star wave energy development. The partnership is focusing on converter and EC-OG’s HALO subsea energy storage system.

New Jersey based Ocean Power Technologies have launched 500m and then 1500m and 4000m systems, a lithium-iron phosphate based Subsea battery system with including a docking system that will allow Eelume a nominal storage capacity of 132 kilowatt-hours.
