[PSUBS-MAILIST] Psubs Barge

Fri Sep 5 16:57:15 EDT 2014

>From a practical point of view, if we did build a PSub Launch barge, it would have to be fairly simple and follow the KISS principle to get it of the drawing board and built by a committee.  I for one don't have the time to design a self powered ship.  I am thinking a larger version of a typical pontoon boat that could be towed by the Boston Whaler.  We would need someone like Jon to be able to set up something like a dropbox account that anyone could populate with files, drawing, sketches, CAD files  etc.  We would have to collectively establish the overall capability of the barge ( how many psubs, maximum weight of psubs, wench/davit system for launch and retrieval, auxiliary systems such as lights).  Someone that has a 3-D cad program like Inventor or Solidworks would have to agree to take sketches and ideas folks come up with and build out 3-D model that we could collectively critique and make suggested changes to.  Someone would need to do the basic
 stability calcs with loaded or partially loaded deck.  Some one would need to do some research on launch and retrieval systems, such as davits  or winches and bring forward a couple of recommendations.  Someone that is a welder (like Dan Lance) would need to review the construction drawing to make sure welding plan is workable.  Someone would have to figure out where you would store the barge when not in use.  Some one would need to figure out a coating plan for the barge.  Someone would have to take on looking at what regulations we would need to meet to use this in the Florida Keys.  Someone would have to do a material takeoff off construction drawings and figure out the cost to build and establish a budget.  If we did build a psub barge, we would need to pole the group and see how many would be willing to split the cost to fabricate based on the estimated cost.  We would need someone to agree to fabricate the weldments and assembly.  We would need to
 figure out where to build it and what it would cost to transport it the Keys.  We would have to figure out how to register such a barge. Would Psubs own the barge or would it make since for Doug to own?  Are there any legal liabilities of having such a barge and if so who would be liable?  We would need someone that is not currently building a psub to agree to be the Barge Bulldog!

Or if someone would agree to do all the above, maybe we just pass the hat and let them do it.

What a rig Brian, and a decomp chamber to boot! 
I like the idea of a group-designed and group-built support ship, my only concern being the logistics of coordinating a project of that magnitude. I'm sure it could be done well given the proper leadership and organization though, especially considering the diverse skillset we would share as a team from designing to fabrication. And I don't think anyone would complain about the benefits of a support barge. 

Thanks for your go-between work Steve. I must admit I was rather unaware of the ISR event until "snooping" through some of Alec's videos. I'm quite intrigued and may well attend this coming year's event regardless of what is decided as a group. Is attendance open to the general public? ~ Douglas S.

The initial feedback from the International Submarine Races (ISR) seems positive to allowing us to piggy back our conference on their event. Their event in 2015 is June 22-26.
