| 128 | Emergency well-control vessel | US086501 | 1979-10-19 | US4336843A | 1982-06-29 | Terry D. Petty |
| The emergency well-control vessel is capable of being moved above an offshore live oil or gas well, over which all normal controls have been lost. The vessel carries special purpose equipments and specially trained personnel for the purpose of bringing the erupted well under control, thereby stopping the pollution of the water body with the ejected formation fluids which form a so-called "plume". Such equipment is adapted to allow the vessel to move over and continue to dispel the plume while simultaneously attempting to regain control of the well. In one aspect, control of the abandoned wellhead and blowout preventers is established with divers working from the vessel or from an auxiliary craft. After control of the blowout preventer stack is confirmed and the same is fully operational, a kill string is lowered through the open blowout preventer stack and as deep down into the well as necessary. Thereafter, weighted fluid is circulated down the kill string and up through the annulus to thereby eventually overcome the formation fluid pressure with greater hydrostatic pressure. In other aspects, the flow can be sealed off with packoffs established against the well casing or against the formation. | ||||||

| 135 | Methods and apparatus for placing underwater guide lines | US591675 | 1975-06-30 | US3983708A | 1976-10-05 | Georges Sylvain Houot |
| Methods and apparatus are disclosed herein for placing a guide line or cable on an underwater well installation connection point in a case where there is already in place a connection line between the surface and the water bottom. By means of a self-carrying electric cable, a vehicle is lowered along the connection line, the vehicle being equipped with a drum on which is wound the guide line having a connector fixed to one end and held vertically on the vehicle. Near the underwater connection point, the vehicle is made to rotate around the connection cable in order to bring the connector into alignment with the connection point. The connector then is engaged with the connection point by allowing the vehicle to further descend, after which the vehicle is raised along the connection line by pulling on the self-carrying electric cable, causing the guide line to unwind from the drum, thereby bringing an end of the line to the surface. | ||||||

| 138 | Anchor means and method of installing the same | US3709182D | 1970-02-24 | US3709182A | 1973-01-09 | HORTON E |
| A drilled-in anchor means and method of installing such an anchor means in a subsea formation, the anchor means including prestressed cable and casing means imbedded in cement which fills an anchor hole in the subsea formation. A subsurface buoy at a selected distance above the surface of the subsea formation provides a connection to a mooring line which may extend from a platform means or other floatable structure. In the method of installing such an anchor means after a drill hole has been made by using a drill casing, the casing is raised a selected distance and then is subjected to stress by a tension cable cooperable therewith, and then the casing and cable means is lowered into the hole. The casing means and hole are then filled with a cement slurry whereby the drill casing and cable are protected against corrosive action of the water.

| 139 | Subsea guideline anchoring method and apparatus | US3603386D | 1969-09-17 | US3603386A | 1971-09-07 | TALLEY WILLIAM A JR |
| A method and an apparatus for locating and anchoring bottom-tosurface guidelines of a subsea guidance and alignment system to be utilized in conjunction with servicing or drilling subaqueous wells by lowering a pair of self-anchoring ends of unanchored guidelines on a spacer frame which is guided to the subaqueous bottom on a pair of previously anchored guidelines. The free guidelines are anchored upon contact of the self-anchoring ends with predetermined anchorage locations on the subaqueous bottom. The operation may be repeated to anchor other guidelines at other anchorage locations on the subaqueous bottom by utilizing the initially free and subsequently anchored guidelines as guides for lowering the space frame carrying the self-anchoring ends of other free guidelines.
