I worked with its predecessor LBT1 installing offshore wind turbine cabling, nice vehicle to operate - loved it.
SMD build some really nice gear.

Like the video simulation of the ROV flying behind it, In reality it would be flying in a cloud of crap coming up from the trencher.

I’m confused why you would want or need to bury a cable on the sea floor. And do you call the 1-800-beforeyoudig number for someone to come out and mark any existing cables?

Might keep anchors from pulling it up.
