What does the term "lockout" of a Synchro-Self-Shifting (SSS) clutch system mean? Illustration GT-0018
Official USCG Answer & Rule Citation
Correct Answer: Option C — SSS clutch will not engage.
Lockout in an SSS clutch system prevents the clutch from engaging, effectively decoupling the gas turbine from the reduction gear. This feature is essential for maintenance or when the vessel requires operation on a different prime mover, ensuring the turbine remains disconnected despite input shaft rotation.
