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 __________.

Question

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&deg;. From the standpoint of critical motion, the motion is __________.

Accepted Answer

Option C: unsatisfactory, ballast to survival draft. Transit stability envelopes for specialized vessels like the DEEP DRILLER define maximum allowable pitch and roll thresholds. A 7-second period combined with a 7-degree pitch angle exceeds safe transit parameters, requiring immediate ballasting to survival draft.
