When preparing/writing shipyard items for your vessel's upcoming dry docking period, what would you consider as an item regarding CuNi salt water cooling systems/piping?

Correct Answer: Option A — Identify in your item all steel waster piece pipe spools in the CuNi systems and require them to be removed and replaced.

Steel waster pieces are sacrificial anodes or transition joints often used in piping systems. If left in a CuNi system, they create galvanic corrosion cells, leading to rapid localized degradation. Identifying and replacing these with proper materials during dry dock is essential to maintaining the integrity of the seawater cooling system.
