Question 5035Deck General70% to pass
While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. GMT is 98.89 feet. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria?
AI Explanation
The correct answer is D) 0.00 feet.
The explanation is as follows:
1. The question is asking to determine how much the KG (center of gravity) corrected for free surface effects should be lowered to satisfy the maximum allowable KG criteria. The given information includes the vessel's draft and the GMT (metacentric height) value.
2. When a severe storm is predicted, the vessel should maintain its original KG value rather than lowering it. This is because the original KG value has already been calculated to ensure the vessel's stability and safety under normal operating conditions. Lowering the KG during a storm could potentially compromise the vessel's stability and should be avoided.
3. The other answer choices (A, B, and C) suggest lowering the KG, which is not the correct action in this scenario.
4. Therefore, the correct answer is D) 0.00 feet, as the KG should not be lowered in this situation.
