Question 4568 Deck General

The correct answer is C) capped and checked for leaks. Prior to backloading portable tanks or drums onto an offshore supply vessel, it is crucial to ensure that each tank is capped and checked for leaks. This is a safety precaution to prevent any potential spills or leaks during the loading process, which could pose a significant environmental and operational risk. Checking for leaks also helps to ensure the integrity of the containers and their contents. The other options are incorrect because: A) Coating the tanks with non-corrosive protection is not a requirement for backloading, as the primary concern is to ensure the tanks are properly sealed and leak-free. B) Painting the tanks yellow with diagonal black striping is not a standard requirement for backloading portable tanks or drums onto an offshore supply vessel. D) Mounting the tanks on pallets is not a necessary step before backloading, as the primary focus is on verifying the tanks are capped and leak-free.
