Turn off the nearest valve, cut off the leaking section, and then weld a new pipe in its place.
First, rule out using 502, as it doesn’t work when exposed to water.
I found that the two people upstairs are really unlearned*; they even thought of using 502 to get along with those guys: lol
It’s not clear whether the old Russians can complete this task on their own; flaw detection is required, as well as lifting and repairing the damaged pipes, checking the drainage system, and making replacements. Help might be needed.
Repairing it is very troublesome; it must not be upright, otherwise seawater will flow back and corrode the pipes. Inert gas protection is required, and a repair facility must be placed underwater to drain the seawater so that repairs can be carried out. In reality, it’s even more complex, requiring cooperation among multiple countries.
Two methods can be considered: 1. Drawing on the design of submarines, create an inverted underwater maintenance section that is placed on the damaged pipe segment on the seabed; seawater is then pumped out by inflating it, and divers are sent down along with materials to carry out routine repairs inside this maintenance facility. Repair work is carried out forward alternately using two maintenance sections. 2. By drawing on the construction method of freezing used for the Hong Kong-Zhuhai-Macao Bridge, the seawater surrounding the damaged area is frozen at low temperatures, allowing workers to descend and gradually clean up and repair the area.
