Question 285Safety & Environmental - 1st Asst/Chief70% to pass
While serving as Chief Engineer on a partially loaded container ship the vessel is involved in a collision. An empty starboard side wing tank becomes open to the sea and the ship takes a starboard list. After investigating the damage it is found that no other adjoining tanks are open to the sea. What action should be recommended to ensure the ship maintains an even keel position?
AI Explanation
The correct answer is B) Ballast a port wing and check the free surface effect for both damaged and intact tanks.
The reasoning is that when a ship takes a list due to damage, the objective is to restore the vessel to an even keel position. Ballasting a port wing tank will counteract the list caused by the flooded starboard wing tank, while checking the free surface effect in both the damaged and intact tanks is crucial to ensure the vessel maintains adequate stability. The free surface effect can reduce the ship's righting ability, so this must be accounted for.
The other options are incorrect because A) and C) focus only on the damaged side, which does not address the list, and D) addresses the vessel's GM (metacentric height) rather than the immediate need to restore the ship to an even keel.
