Robotic tunnel vision
Tunnel drilling is no new idea, but filling it with water and submerging the Seabed Rig robotic drilling solution to do the job is.
"Though the concept of drilling for hydrocarbons via tunnels from shore has been floating around in different forms for some years already, so far they've all been rejected due to safety aspect. With good reason: It would take just a minimal gas leak in one of those tunnels for workers to pass out.
Initially, the idea is to use a tunnel solution in relation to hard-to-rach Russian river deltas in the Artic."
