Question 2911 Deck General

The correct answer is C) continued progressive flooding. Repairing damage to the hull of a Mobile Offshore Drilling Unit (MODU) at or above the waterline reduces the threat of continued progressive flooding. This is because hull damage above the waterline can allow water to enter the MODU, potentially leading to progressive flooding and instability. By repairing such damage, the risk of continued flooding and potential capsizing of the MODU is diminished. The other options are incorrect because: A) wind overturning moments are not directly related to hull damage above the waterline, B) free surface effects are more associated with damage below the waterline, and D) capsizing is a consequence of continued progressive flooding, not the threat itself.
