Question 3374 Deck General
70% to passYour semisubmersible drilling unit is moving onto a location in shallow water with a very hard bottom. What is the most effective means of maintaining your position at this location during severe weather?
A
Install fluke angle blocks on all your LWT anchors
B
Running out all the anchor chain available
C
Piggyback all anchors and pretension to above the expected tensions
D
Remove fluke angle blocks on all your LWT anchors
AI Explanation
The correct answer is C) Piggyback all anchors and pretension to above the expected tensions. This is the most effective means of maintaining position for a semisubmersible drilling unit in shallow water with a hard bottom during severe weather. Piggybacking the anchors and pretensioning them to above the expected tensions provides the greatest holding power and stability to withstand the extreme forces of the weather. The other options, such as adjusting fluke angle blocks or running out all anchor chain, would not offer the same level of secure positioning in these challenging conditions.
