Abstract
A power generation grid for a vessel, rig or platform includes a primary energy source located above the waterline and a plurality of DC sub-assemblies, located below the waterline. Each DC sub-assembly has a DC bus, a DC/DC converter adapted to couple the DC bus to a DC energy source; an AC/DC converter adapted to couple the DC bus to an AC energy source; a DC/AC converter adapted to couple the DC bus to a corresponding load, and a first switch adapted to couple the DC bus to a DC bus of another DC sub-assembly.

A power generation grid for a vessel, rig, or platform, the grid comprising:
- a primary energy source located above a waterline,
- a plurality of DC sub-assemblies, located below the waterline;
- wherein each DC sub-assembly comprises a DC bus, a DC/DC converter adapted to couple the DC bus to a DC energy source;
- an AC/DC converter adapted to couple the DC bus to an AC energy source;
- a DC/AC converter adapted to couple the DC bus to a corresponding load, and a first switch adapted to couple the DC bus to a DC bus of another DC sub-assembly;
- wherein each DC sub-assembly further comprises a second switch adapted to couple the DC bus to a DC bus of one other of the plurality of DC sub-assemblies;
- and
- wherein each DC sub-assembly further comprises a third switch, adapted to be coupled to a DC bus of another of the plurality of DC sub-assemblies.
