ABSTRACT:
A guidance apparatus for re-entering a sub-sea wellhead or christmas tree after the guidelines extending to the water surface have been removed. The apparatus includes a remotely actuated marker buoy secured by a reeled line to an upwardly projecting keyed buoy post at the wellhead and a second upwardly projecting keyed post is positioned near the well centerline adjacent to the buoy post and the wellhead. The apparatus also includes a re-entry funnel adapted to be run from the surface on a cable attached to either post and having an internal cam engageable by the key on the post to orient the re-entry funnel and align any tools carried thereby with respect to the wellhead, tree or other parts of the sub-sea wellhead structure.
