 FACT: Even if the wind force on the Benthic Explorer is enough to  drag the massive rig along the seabed, it could never be enough to  accelerate it from rest to at least 1 mph in less than a second when  transmitted over an umbilical cord at least 2,000 feet long. No  matter how strong the cord is, over that length it would have to  stretch to some extent and this would limit the acceleration.
