-Easily repairable may be a stretch, it is my understanding there are no shutoff valves along the length of the pipeline, so if they're all breached (4 pipes, each ~1200km long, slightly over 1m in diameter) then that's about 5B liters of water which needs to be pumped out after whatever damage done where they were punctured has been repaired. (Presumably the water inrush is slowed by the escaping gas sufficiently so that the pipeline doesn't sustain further damage, but I'm just guessing. Being an electrical engineer this is way outside what I dabble with on a day-to-day basis)
