Thanks for doing the math, looks plausible to me. Just for the argument sake, since there seem to be logistical problems (hey, Hanoi is not that far away, right?) to the whole solution: you could carry out several non-adjacent welds in parallel and then join these segments together, that would speed things up. The data cable seem to have water damage problems, something that would not be a concern here it seems.

How do the divers get to the non-adjacent welds if the pipe blocks their way? How are they supplied? Why should we assume that the require equipment won't also suffer from water damage? Eg, "around small passages" might mean the cable scraped against the wall, causing water to leak in. BTW, it seems the critical section is under 5 meters of water, not 6 as I thought, and is 70cm across. And it seems one of the divers just died. If that's an indication of the mortality rate, then imagine how many might die building a tube.
