The riser has generally planar fins extending radially outward from its outer diameter. The centralizing device has a frame which is mounted to the platform about the riser. A plurality of centralizing rollers are mounted to the frame and are radially extensible relative to the riser. The centralizing rollers bear against the riser and retain it laterally.
