How about we dial back the tone a bit. I’m an engineer. I’m in the Marine Technical Society and Society of Naval Architects and Marine Engineers. I have dealt with failures in mature technology embodiments. This is not such.
So… if you have the answer: what is the first mode of failure for cyclic loading based on standard seas as a basis for infinite life and then a 5x design margin for a worst case storm season all for the site in question. Coupled with this, what is the corrosion prevention scheme for stress corrosion cracking? What is the maintenance cycle? What are the field tools proposed? What is the reliability scheme?
NONE of this is trivial, especially since the other sections indicate the majority of the people involved are “passengers” as opposed to working, trained, skilled crew.
If you are going to be rude and act like you have the answers, give it up. Show me. If you don’t have the answers, then they are not addressed, they are talk about and are put on hold for a later time. These issues are life and death.
