hook them into the grid- ship to shore power.
Cubans are resourceful people. Ships can also sail away and get more diesel somewhere else.
Not ideal, but it'd work.

Ships don't generally have the equipment to bring their generators into phase with an external power system (why would they?), so you'd end up with 2/3 of the power from the port going to heat up the ship's generators.
