The full period of motion of the DEEP DRILLER while in transit is 7 seconds and the maximum pitch angle as seen on the inclinometers is 7°. From the standpoint of critical motion, the motion is __________.

Correct Answer: Option D — unsatisfactory, ballast to survival draft

Evaluated against MODU stability manuals and motion criteria, a 7-second period with 7-degree pitch during transit exceeds allowable dynamic thresholds, requiring ballasting to survival draft to mitigate severe structural slamming and green water impact on deck.
