70% to pass

The full period of motion of the DEEP DRILLER while tripping is 8 seconds and the maximum pitch angle as seen on the inclinometers is 4 degrees. From the standpoint of critical motion, the motion is _______________.

A unsatisfactory, place unit in standby
B unsatisfactory, place setback in the pipe racks
C satisfactory, continue tripping
D unsatisfactory, deballast to survival draft
AI Explanation

The correct answer is C) satisfactory, continue tripping. The key factors here are the full period of motion (8 seconds) and the maximum pitch angle (4 degrees). Based on industry standards and regulations, a full period of motion between 8-12 seconds and a maximum pitch angle below 5 degrees are considered satisfactory for tripping operations. Since the motion parameters provided fall within these acceptable limits, the rig's motion is satisfactory, and the tripping operation can continue as normal. The other options are incorrect because they suggest taking actions that are not necessary given the satisfactory motion conditions. There is no need to place the unit in standby, set back the pipe, or deballast to survival draft, as the motion is within acceptable limits for continued tripping.
