Abstract
An improved flexible joint elastomer protection tool is described, which can be actuated and removed by a remote operated vehicle ('ROV'), the tool having pivot arms that can be rotated from a closed position to an open position. Rotation inward to the closed position results in the compression of the elastomeric component in an offshore flexible joint. Rotation outward to the open position results in the de-compression of the elastomeric component in an offshore flexible joint. Rotation of the arms can be accomplished using mechanical, hydraulic or other mechanisms that can be operated by an ROV.
