Question 29Gas Turbine - 1st Asst/Chief70% to pass
On a ship with a marine gas turbine as shown in the illustration, a fire emergency stop is initiated when _______________. Illustration GT-0017
AI Explanation
The correct answer is D) all of the above.
A fire emergency stop on a ship with a marine gas turbine is initiated when any of the following occur: 1) one of the UV flame detectors is activated, 2) either the primary or reserve GTM CO2 system activates, or 3) the GTM fire emergency shutdown switch located on the module is activated. All of these events will trigger the fire emergency stop protocol to shut down the gas turbine and activate the appropriate fire suppression systems. The reasoning behind this is that a ship's gas turbine system requires multiple redundancies and fail-safe mechanisms to ensure safe operation and rapid response in the event of a fire emergency.
