Which of the following conditions can cause high salinity of the distillate due to sea water leakage in the illustrated device. MO-0110
Official USCG Answer & Rule Citation
Correct Answer: Option D — Failure to properly tighten the bolts of the condenser heat exchanger.
The condenser heat exchanger separates the cooling medium from the vapor space. If the plate or tube bundle bolts are not properly tightened, the seal fails, allowing high-pressure seawater to leak directly into the distillate side, causing a significant and immediate rise in the salinity of the produced water.
