This beauty weighs 60 tons (out of the water) and has a length of 7.8 meters, a width of 7.8 meters and a height of 5.6 meters. In fact, it has the dimensions of a small house but is more expensive, carrying a price tag of about £10 million. It can move at a speed of 2 to 3 knots under the sea. And it can trench pipelines with a 1-meter diameter in deep waters of up to 1,500 meters."
