[PSUBS-MAILIST] K-250 help

[David Colombo via Personal_Submersibles]

Hi Scott,
I am working here on the west coast with a company that is quoting the
fabrication of the SeaQuestor pressure hull. While not a k-boat, the steel
type and diameters are similar. I should have a complete quote for
fabrication and welding and welding certs, early next week, in both A516-70
and 2205 duplex (corrosion resistant, no painting required), and an epoxied
finished A516-70 version. Only draw back is that fabrication would not be
complete until October based upon their work load, and if the price is
right for me. I asked them about the ASME spec and as they build pressure
vessels, their roundness spec requires better than ASME to get these parts
to nest, so I am told we can achieve the tolerance.  Oh, and they do know
that it is a submarine pressure hull that they are building!!  Stand by....


Best Regards,
David Colombo
