[PSUBS-MAILIST] Life boats

Mon Aug 10 18:28:13 EDT 2020

Brian, thank you for your correspondence. Regarding the matter at hand, I
am less of an engineer and more of a general consultant/emissary in the
venture I described. The group of engineers is mostly comprised of STEM
students at Berkeley, and I can certainly arrange for a trailer to
transport the vessels to their storage and work facilities there. If the
oil company is willing to provide its own trailers, even better. However, I
failed to realize the vessel currently has no ability to submerge. Based on
your current knowledge of the vessels, do you think they can be converted
into submarines if a ballast tank system and whatnot are installed?
