| 201 | Sub-sea well re-entry guidance apparatus | US531706 | 1974-12-11 | US3954137A | 1976-05-04 | Benton F. Baugh |
| 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. | ||||||

| To replace a broken underwater guide line or cable extending from a guide post, at a well bore location, to a floating drilling vessel, a remotely operable apparatus is lowered along one or more intact guide lines and accurately positioned to cut off the disrupted line at the top of the guide post, whereupon a replacement intact guide line is attached to a connector carried by a remotely operable apparatus, and lowered through the water to position the connector over the guide post and firmly secure it thereto, the apparatus being released from the underwater connector and withdrawn. If the line secured to the connector breaks, such line can be severed at the top of the connector and the connector withdrawn to the drilling vessel, a replacement intact line being secured to the connector, or a substitute therefor, which are lowered to the guide post and secured thereto. At any time, the connector with an intact line attached thereto can be released from the guide post and withdrawn to the drilling vessel.

| 204 | Apparatus and method for drilling and producing multiple underwater wells | US3618661D | 1969-08-15 | US3618661A | 1971-11-09 | PETERMAN CHARLES P |
| Apparatus and method for drilling and producing multiple underwater wells wherein drilling and production template means is remotely lowered and installed at an underwater location. The template means comprises a plate having a plurality of holes therein through which underwater well drilling operations may be carried out. A plurality of guideposts on the template means and guidelines associated therewith are utilized to lower into position the various drilling and production components operatively associated with each of the wells.

| 205 | Ocean descent system method and means | US3609981D | 1969-07-08 | US3609981A | 1971-10-05 | COOK ROBERT G |
| IN OFFSHORE OIL PRODUCTION OPERATIONS, A PLATFORM IS INITIALLY SECURED TO THE OCEAN FLOOR, AND A SUBMERSIBLE HOUSING IS THEREAFTER HAULED DOWN FROM THE OCEAN SURFACE IN PRECISE DIRECTIONAL OREIENTATION WITH RESPECT TO THE PLATFORM, AS REQUIRED FOR MATING OF STRUCTURAL ATTACH CONNECTIONS THEREBETWEEN. ORIENTATION IS ACHIEVED BY USE OF A U-SHAPED HAWSEPIPE ON THE PLATFORM, THROUGH WHICH THE HAUL-DOWN HAWSER IS THREADED, THE PIPE ENDS BEING SPACED APART A FIXED DISTANCE. A GUIDE ARM SYSTEM MOUNTED ON THE HOUSING ENGAGES THE HAWSER AT TWO LOCATIONS SPACED APART A DISTANCE COINCIDING WITH THE MENTIONED PIPE ENDS. LOOKING CONNECTION ELEMENTS ON THE PLATFORM AND HOUSING INTERENGAGE AUTOMATICALLY DUE TO PRECISE ORIENTATION THEREBETWEEN AS THE HOUSING MOVES INTO MATING RELATIONSHIP WITH THE PLATFORM.

| 206 | Removable guide base | US3559754D | 1968-07-10 | US3559754A | 1971-02-02 | MORRILL CHARLES D |
| A removable guide base for an underwater wellhead comprising a hub member having a vertical passage therethrough telescopically positionable around a wellhead. Structural support members project radially outward and slightly inward of the hub member. An upper set of the inner projections provides a downwardly facing support surface engageable with support ribs on the wellhead. A lower set of the inner projections provides an upwardly facing surface engageable with the wellhead support ribs to prevent longitudinal movement of the guide base relative to the wellhead. The lower set of inner projections is slidable between the wellhead support ribs and rotatable thereunder to the position of engagement as the hub member is lowered around the wellhead and rotated. A latch sleeve is nonrotatingly mounted within the hub member for longitudinal movement between adjacent wellhead ribs to prevent disengagement of the lower set of inner projections. Methods for using the guide base are also disclosed.
