The St. Petersburg-based Malakhit Marine Engineering Bureau (part of United Shipbuilding Corporation) is working on the design of a submersible underwater energy module.

Using the submersible power module, it will be possible to supply energy to facilities where it is impossible to build conventional power plants, for example, to power Arctic shelf fields with difficult ice conditions or military units in remote coastal areas of the Arctic.

The submersible will be able to dive to a depth of up to 400 meters and stay there for extended periods. This will reduce the risk of collision with icebergs. The module will operate autonomously with periodic maintenance: every three months it will be checked by up to six specialists. It will be able to receive personnel and cargo due to the possibility of docking with underwater manned vehicles.
