Question 4287Deck General70% to pass
While on a normal tow, the COASTAL DRILLER is threatened with the approach of a severe storm. The legs should be lowered so that the TOC (tip-of-can) is lowered from 1.20 feet to _______________.
AI Explanation
The correct answer is D) 60.50 feet.
When a severe storm approaches while a coastal drilling rig like the COASTAL DRILLER is on a normal tow, the legs should be lowered so that the tip-of-can (TOC) is lowered to 60.50 feet. This is the recommended practice to ensure the rig remains stable and secure during the inclement weather. The other answer choices are incorrect because they do not represent the proper TOC height for storm preparation on a coastal drilling rig.
