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 distillate. If bolts are not properly tightened, gasket failure or plate misalignment allows seawater to leak into the distillate side. This cross-contamination directly increases the salinity of the produced water, violating purity standards for shipboard potable water systems.
