Abstract
A tensioner anti-rotation device and method that transfers rotational force from an offshore platform deck to a riser in response to waves and currents. The device includes a bracket mounted on the deck, and a rib that transfers force from the deck through the bracket, to the rib, and into the riser such that the tensioners on the riser are not subjected to torque.
