ABSTRACT:
An offshore oil or gas recovery station is established by docking a jacket with a submerged wellhead and supporting a platform on the jacket above the water surface. The jacket is lowered upon the wellhead so that a guide collar on the jacket passes downwardly around the wellhead. Alignment pins on the guide collar are fully advanced by a diver so as to contact the wellhead and effect alignment between the wellhead and a conduit which is carried on the jacket by a temporary connection. The conduit is released and is lowered onto the wellhead for connection therewith.
