Question 3402Deck General70% to pass
The full period of motion of the DEEP DRILLER while tripping is 10 seconds and the maximum pitch angle as seen on the inclinometer is 4 degrees. From the standpoint of critical motion, the motion is _______________.
AI Explanation
The correct answer is A) satisfactory, continue tripping.
The reasoning is that the full period of motion (10 seconds) and the maximum pitch angle (4 degrees) are within the acceptable limits for critical motions during tripping operations. This indicates that the vessel's motions are not excessive and can be safely continued without the need for additional actions like placing the setback in the pipe racks, deballasting to survival draft, or putting the unit in standby.
The other options are incorrect because the vessel's motions are not unsatisfactory, and there is no need to take the more drastic measures suggested in answers B, C, and D.
