I said “cable-laying,” get it? Anyhoo, if you’re in the market for a huge remote controlled submersible robot that weighs 50 tons and can bury oil and gas pipes at the bottom of the ocean, look no further than the Ultra Trencher 1 by a company called SMD. It uses propellers to submerge itself to depths up to a mile and then uses ninja-like high-pressure “jet swords” to cut a trench in the ocean floor. Pipes can then be safely buried out of the way of shipwrecks, fishing equipment, and currents.
