The apparatus includes a gripping mechanism configured to straddle the flange coupling and grip both of the first and second conduit components. The gripping mechanism is mounted on a lifting frame able to bear the loadings upon the gripped components during a moving operation. The apparatus includes a base frame with a gripping mechanism to receive the flange coupling. The coupled components are gripped on each side of the flange coupling to maintain the fluid integrity of the flange coupling.
