If you knew the exact position of the pipes, why would there be a problem with precision? Maybe there are lighthouses in sight which you could use to line up exactly, maybe you'd use gps/glonass, maybe you'd have some plane go by near at a specified time, doing it for you, saying via radio, all good, drop it?
