On a propulsion marine gas turbine, if full power temperatures become excessive, what action should the operator take?

Correct Answer: Option B — Reduce power to stay within limits.

Excessive gas turbine temperatures indicate potential thermal distress or impending component failure. Reducing power is the immediate operational requirement to lower internal firing temperatures and protect the turbine blades and nozzle guide vanes from catastrophic thermal damage, ensuring the engine remains within its certified operating envelope and safety limits.
