Re: [PSUBS-MAILIST] 200ton 18meter Live aboard submarine

Carsten - I had been meaning to ask you this question about Euronaut - 
presumably, you designed your bow structure to this recommendation?  In the 
event of a 3-4 knot impact, is there energy absorption through buckling of 
the steel by design, or is the entire structure strong enough to stay below 
yield?  Also, since a likely scenario for sub collision is not a straight 
head-on impact but rather a strike close to the bow point, but at some angle, 
would you consider (or did you employ) additional hull stiffening throughout 
the entire bow section?
