Question 5033Deck 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. VM are 541,257 ft-kips, FSML are 32,000 ft-kips and FSMT are 24,000 ft-kips. How much should the KGL be lowered to satisfy the maximum allowable KG criteria?
AI Explanation
The correct answer is B) 1.96 feet.
To determine the correct answer, we need to calculate the maximum allowable KG (vertical center of gravity) based on the given information. The maximum allowable KG is determined by the vessel's stability criteria, which must be satisfied to ensure the vessel's safety during the predicted severe storm.
The key information provided is the vessel's draft, VM (vertical moment), FSML (forward static moment of loose loads), and FSMT (total static moment of loose loads). Using these values, we can calculate the required KGL (vertical center of gravity) adjustment to satisfy the maximum allowable KG criteria.
The other answer choices are incorrect because they do not accurately reflect the necessary KGL adjustment based on the given information and stability requirements.
