Question 4595 Deck General

The correct answer is D) progressive flooding. A continual worsening of the list or trim of any floating MODU (Mobile Offshore Drilling Unit) indicates progressive flooding, which is the gradual accumulation of water within the vessel's compartments or spaces. This condition can lead to a loss of stability and eventual capsizing if not addressed promptly. The other options are incorrect: A) negative GM (Metacentric Height) would indicate a stability issue, but not necessarily progressive flooding; B) structural failure could also lead to a worsening list or trim, but is a different underlying cause; and C) an immediate need to counterflood is a potential response to the situation, but does not describe the underlying issue.
