...and from the odd-ball files:
A concern with disaster relief efforts these days is what happens to a major coastal town or city which is cut off from the electrical grid or has its local power source severely damaged. The answer is to have a diesel powerplant on a barge, ready to be towed to the stricken location. The barge would be anchored close ashore or tied up at an intact pier, and then weather-resistent cables would be run ashore and spliced into the local power grid, such as it was.
This particular barge, built to civilian standards, has four 2,500 KW diesel generators, with fuel to supply ten days of full operation. This will not restore full power to a large city, but should fully light up a smaller community of several thousand or allow key services such as hospitals to function in larger communities.
As a reference point, the modern community of Iqaluit, Nunavut (6,700 people) has a max capacity of 15.1 MW; one expects a similar-sized community of the 1940s to have substantially less need.
Obviously, you should ignore the speed/seakeeping figures - the machinery is there to represent the powerplant. The barge is unpowered, but its freeboard should keep it plenty dry. At fifteen knots, its seakeeping value is around 1.75.
