70% to pass

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 4 degrees. From the standpoint of critical motion, the motion is _______________.

A unsatisfactory, ballast to survival draft
B satisfactory, continue transit
C unsatisfactory, change course and speed
D unsatisfactory, place unit in standby
AI Explanation

The correct answer is B) satisfactory, continue transit. The key factors here are the period of motion (7 seconds) and the maximum pitch angle (4 degrees). According to industry standards, a period of motion between 6-10 seconds and a pitch angle less than 5 degrees are considered satisfactory for transit operations. Since the given values fall within these acceptable ranges, the motion of the DEEP DRILLER is satisfactory, and the unit can continue its transit as planned. The other options are incorrect because they suggest the motion is unsatisfactory and would require actions like changing ballast, course, or placing the unit in standby, which are not necessary given the satisfactory motion characteristics.
