Aboard ship, single-shaft gas turbines are used mostly as prime movers for which of the following applications?

Correct Answer: Option C — Generators

Single-shaft gas turbines maintain a constant rotational speed, making them ideal for driving electrical generators. Because the compressor and power turbine are mechanically coupled, they provide the stable frequency output required for shipboard power distribution, unlike split-shaft designs which are better suited for variable-speed propulsion applications.
