Contrary to what the Chinese government said, I believe that the cause of the accident aboard a Chinese sub which killed seventy people was chlorine gas resulting from sea water getting into their batteries. They claimed it was due to an engine explosion. The sub was towed back to port intact.
I also believe that the cause of the boiler explosion aboard the cruise ship SS Norway in which six crewmembers were killed and many others injured was lack of or improper boiler feed water treatment which caused "embrittlement".
