Generator Barge #1 class

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-resistant 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.

Distillation Barge #1 Class

Based on the Generator Barge design, but the diesel powerplant is replaced by a desalinization/distillation facility intended to provide fresh drinking water from seawater. As with the generator barge, these would be towed to an affected area, secured to a pier/port, and water lines run ashore in some fashion.

Lieutenant Abul Majumdar Class Depot Ship

Though Bharat has six large depot ships, all of the hulls date back to the early twenties. Moreover, the quantity of depot ships is beginning to lag behind operational requirements. The expansion of the submarine arm is one such issue; the use of depot ships to establish a Bharati naval presence n places like Karachi and Porbandar is another.

While the BNS has a long-term need for both submarine depot ships and general-purpose depot ships, it is the former that will receive immediate attention. At least four units will be constructed, following which one or two of the older Grival class tenders will be re-assigned to general-purpose depot functions. BNS planners expect that another run of four or so new depot ships would be ordered from 1949 onward to replace the Sen class.

The class is being built to civilian standards.
