Question 4478Deck General70% to pass
The DEEP DRILLER is on location during a storm. Windward anchor tensions begin to exceed the test tensions. To reduce tensions while minimizing offset over the well, you should _______________.
AI Explanation
The correct answer is C) reduce tension on the leeward chains.
Explanation:
When anchor tensions on the windward side exceed the test tensions during a storm, the appropriate action is to reduce the tension on the leeward chains. This helps to minimize the offset over the well while also reducing the overall anchor tensions. Increasing tension on the leeward chain (option A) or paying out more chain on the windward side (option B) would not effectively reduce the overall anchor tensions. Connecting an emergency tow wire to the work boat (option D) is not the appropriate action to take in this situation.
