Question 3399Deck 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 inclinometers is 8 degrees. From the standpoint of critical motion, the motion is _______________.
AI Explanation
The correct answer is A) unsatisfactory, deballast to survival draft.
The key factors here are the full period of motion (10 seconds) and the maximum pitch angle (8 degrees). Based on industry standards and regulations, if the full period of motion exceeds 8 seconds and the maximum pitch angle exceeds 6 degrees, the motion is considered unsatisfactory from a critical motion standpoint. In this case, with a 10 second period and 8 degree pitch, the motion is unsatisfactory and the proper action would be to deballast the unit to its survival draft.
The other options are incorrect because: B) and C) indicate the motion is satisfactory, which is not the case given the parameters provided; and D) refers to placing the setback in the pipe racks, which is not the appropriate response for an unsatisfactory critical motion condition.
