Abstract:
An apparatus for, and method of, reducing a pendulum motion of a piece of subsea equipment during a landing operation includes a frame assembly arranged for connection to the piece of subsea equipment; a sheet of arrestor material disposed within a perimeter of the frame assembly, and a drive mechanism arranged to move the sheet of arrestor material between a first position and a second position, each position providing a different amount of surface area than the other to create a different drag force on the equipment.
