What did an oil-fired ship's stoker do?

What did a stoker do on an oil-fired warship compared with a coal-fired ship?

Stokers remained responsible for efficient boiler operation, including oil feed, water flow, and the maintenance of the machinery around the steam plant.

Oil firing changed how fuel reached the burners, but skilled stokers still had to run the steam plant. A stoker monitored the rate and density of oil entering the burners so that the boilers produced steam efficiently. Water flow, pipes, and the machinery surrounding the boilers also fell within the role. Reliable propulsion depended on this continuous engineering work.
