Following cargo loading operations, your vessel is experiencing an excessive at-sea hogging bending stress as shown in the illustration. What should you do to reduce the bending moment? See Illustration SF-0047
AI Explanation
The correct answer is B) Add ballast to an amidships tank.
Explanation:
Adding ballast to an amidships tank helps reduce the excessive hogging bending stress by shifting more weight towards the center of the vessel. This counteracts the bending moment caused by the cargo loading, bringing the vessel back into a more even trim and reducing the hogging stress.
The other options are incorrect because:
A) Adding ballast to the forepeak tank would not counteract the hogging stress, and may even exacerbate it.
C) Adding ballast to the after peak tank would not effectively reduce the hogging stress.
D) Removing ballast from an amidships tank would further increase the hogging stress.
