Working in teams of two we were charged with putting together a ‘pipe puzzle’. When we reached to seabed we found a bucket filled with the pipe pieces, 2 wrenches and Teflon tape. The assembled pipe was supposed to be a square with one side having a T piece with an inflator nipple, which allowed our instructors to pressure test our pipes at the surface for leaks. The side opposite the T piece was supposed to have a coupling which would allow for the pieces to be tightened and assembled correctly. The two adjacent sides were matching long pipe pieces.
The most difficult part of this project was making sure the pieces came together correctly. Since the t and the coupling were different sizes the 4 pipe pieces given for those two sides were all different sizes. This made it so that there was only one correct way to assemble the pipe where the coupling would close correctly. I think all the teams ran into the problem of not having the coupling be able to close, which I can say from experience, was a frustrating moment underwater.
This was a fun project to do and though any one of us would have been able to put the pipe together at the surface in under 30 minutes underwater it took quite a bit longer.
