Question 4Safety & Environmental - 1st Asst/Chief
70% to passThe 2nd assistant engineer has just finished fueling operations. After entering the fuel data into the loading computer you notice a greater than allowable at-sea bending stress. After the chief mate checks the voyage cargo data the vessel still has an excessive at-sea hogging bending stress. As Chief Engineer and after consulting with the Chief Mate, what should your instructions be to reduce the bending moment when ballasting the vessel?
The correct answer is A) Add ballast to an amidships tank. The reasoning is that adding ballast to an amidships tank will help reduce the excessive at-sea hogging bending stress on the vessel. Hogging is when the center of the vessel is bent upwards, and adding ballast amidships helps to counteract this and reduce the bending moment. This is in accordance with standard vessel stability and loading practices. The other options are incorrect because adding ballast to the after peak or forepeak tanks (B and C) would not effectively reduce the hogging bending stress, and removing ballast from an amidships tank (D) would actually increase the hogging stress. The key is to add ballast strategically amidships to counteract the excessive bending moment.
