What a crock.
I'll bet they have had numerous downflooding incidents. It gets under the subflooring and goes all though that deck and lays against the steel for years. I wonder what their deck camber is. The water would lay against the hull if it is of any significance.
I wonder exactly how much steel they replace other then ribs So many questions in my curious engineering mind.
The rust problem is linked to mould reportedly discovered in all of Canada’s frigates, said Ken Hansen, a military analyst and retired naval commander living in Dartmouth.
“Humidity in the ships is too high,” Hansen said. “I know they’re looking for a good solution to the problem.”
The hull of warships is typically cold because of the outside ocean temperature, he said.
Warm, moist air caused by more than 200 sailors living inside a ship, as well as heat from the engines and electronics, condenses when it hits the cold steel, Hansen said.
“All that heat carries moisture. So unless you can do something about that moisture through your dehumidifying system, it’s just going to get worse,” Hansen said.
The air inside warships is 90 per cent recirculated, he said. “They only take in a little bit of air from the outside, and the rest is continually being recirculated by these air conditioning and ventilation systems.”
