🔍 Key Concepts

• Difference between online (while running) compressor water wash and offline (crank) water wash in marine gas turbines • How airflow volume and compressor speed affect the ability of water droplets to carry contaminants through the compressor without causing damage or stall • Why very high power settings may be avoided during washing (thermal stress, flame stability, erosion risk)

💭 Think About

• Look at the answer choices and separate those where the turbine is producing power from the one where it is only being rotated. For routine washing while operating, which group makes more sense? • When spraying water into a running compressor, do you want too little airflow, moderate but strong airflow, or maximum possible airflow? How would each affect the risk of stall, flameout, or blade damage? • Which setting would likely be reserved for a shutdown or maintenance wash, rather than a routine online wash done during normal operations?

✅ Before You Answer

• Confirm which option represents an offline/cranking condition instead of producing power • Eliminate any option that would create excessive thermal or mechanical stress on hot-section parts while injecting relatively cool water • Select from the remaining powered options the one that gives strong, steady airflow through the compressor without being at extreme full-load conditions
