Which type of engine is commonly used to drive a ship's service generators?

The main idea is that ship service generators are typically powered by a dedicated diesel engine that is directly connected to the generator in a single-shaft arrangement. This single-shaft setup keeps the genset compact, simple, and reliable, which is ideal for constant, dependable electrical power aboard a vessel. Each generator set is usually its own unit with one engine driving one generator, and multiple sets can be run in parallel to meet demand or supply backup power. Using a dual-shaft or multi-shaft layout adds unnecessary complexity for generator drives, and an auxiliary shaft isn’t a standard way to describe how a generator is driven. So the straightforward, common configuration is a single shaft.
