No. 810,733 Int. Cl. E02b 1/00 U.S. Cl. 61-34 11 Claims ABSTRACT F THE DISCLOSURE A well installation apparatus and method, particularly for offshore wells, utilizing a large Colfer or caisson surrounding the well point, such coffer or caisson including a submerged caisson having secured to the top thereof an annular axially expansible substantially water impermeable extension secured at its lower end to the top of the submerged caisson and at its top to a floating ring.
This invention relates generally as indicated to a method and apparatus for containing well pollutants and more particularly to a coller or caisson construction for enclosing offshore wells to prevent the escape of pollutants such as drilling tailings, mud, brine, oil and the like. This invention represents certain improvements in appplicants copending application filed Mar. l, 1968, Ser. No. 709,704, entitled, Method and Apparatus for Containing Well Pollutants.
In the drilling of offshore well installations, the containment of pollutants such as oil, mud, brine, drilling tailings, etc., can be a serious problem. If the well is drilled in a considerable depth of water it is diicult to provide a caisson or coffer which will adequately contain any pollutants which might result.
It is accordingly a principal object of the present invention to provide a coffer or caisson for an offshore Well installation which will adequately contain pollutants resulting from the well regardless of the depth of water in which the well is completed.
Another principal object is the provision of apparatus for containing offshore well pollutants which includes a submerged coffer or caisson to which is secured an annular extension which is axially expansible and secured at its top to a floating ring.
Still another principal object is the provision of a coffer or caisson of flexible water impermeable material which is anchored to the bottom and supported at its top by a floating ring.
Still another object is the provision of a container for offshore well pollutants which comprises an axially expansible water impermeable flexible cylindrical structure which may quickly and easily be installed about an olfshore well point.
A still further object is the provision of a caisson for containing well pollutants which includes a flexible accordion extension, the lower end of which may readily be submerged and secured in place.
A still further object is the provision of a process for containing olfshore well pollutants which comprises anchoring the lower end of a flexible cylindrical liquid barrier while the upper end is floated about the well point.
Other objects an advantages of the present invention will become apparent as the following description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, the following description and the annexed drawing setting forth in detail a certain illustrative embodiment of the invention, this being indicative, however, of but one of the various ways in which the principles of the invention may be employed.
3,561,220 Patented Feb. 9, 1971 In said annexed drawing:
FIG. l is a fragmentary schematic illustration of a caisson placed in the bottom surrounding an offshore well point;
FIG. 2 is a fragmentary horizontal section taken through the top of the caisson as seen substantially from the line 2-2 of FIG. 1;
FIG. 3 is a view similar to FIG. l illustrating the axial flexible caisson extension secured in place;
FIG. 4 is a fragmentary vertical section showing in greater detail the axial caisson extension;
FIG. 5 is a top plan view of one of the ring segments forming the floating top or the submerged 'bottom of the axial extension; and
FIG. 6 is an enlarged vertical fragmentary section taken substantially on the line 6-6 of FIG. 5.
Referring now first to FIG. l, it will be seen that an anchoring or footing caisson shown generally at 10 may lbe driven into bottom 11 submerged beneath body of water 12. The caisson may be driven through the bottom 11 to clay 13 or other suitable solid substructure. The annular caisson 10 may be formed of corrugated sheet p111ng sections such as seen at 15 and 16 in FIG. 2 with each section being provided with lateral mating flanges indicated at 17 and 18 secured together by fasteners 19. A seal seen at 20 may be provided between such flanges.
The piling may be driven under water using an annular form 1n conventional manner. The diameter of the annular casing may be selected based upon the size and number of'well points to be completed within the caisson. The calsson may be several hundred feet in diameter, for example.
Secured to the interior of the footing caisson is an adaptor ring 22 and the corrugations of the piling may be provided with a suitable sealant seen at 23 so that the caisson is connected to the adaptor ring in an essentially watertight manner.
As seen perhaps more clearly in FIG. 4, the upper interior portion of the adaptor ring 22 is provided with a plurality of downwardly and inwardly projecting locking fingers 25. Such fingers cooperate with apertures 26 in anchoring ring 27, the details of which are seen more clearly in FIGS. 5 and 6. Such anchoring rings may be comprised of a plurality of interconnected arcuate sections, one end of each section being provided with a tongue seen at 28 while the opposite end is provided with groove or slot 29.
The anchoring ring sections may be constructed of a reinforced rubberized fabric material and include an arcuate vertically elongated chamber 30, the interior wall of which is connected through web 31 to vertically extending interior ring 32. The apertures 26 are provided near the lower edge of the ring 32 on the same peripheral or arcuate spacing as the lingers 25. The top of the ring 32 is also provided with a series of similarly spaced and shaped apertures as seen at 34. The chamber 30 of each ring sector is provided with valves seen at 35 so that either air or liquid may be admitted into such chamber.
The top of the adaptor ring 22 its into the downwardly facing slot 36 between the interior wall of the chamber and the lower portion of the interior ring 32. The `fingers 25, of course, ft within the apertures 26 securing the anchor ring 27 to the top of the adaptor ring 22.
The anchor ring 27 is also secured in similar manner to flexible caisson extension 37. The lower cylindrical axial portion 39 of the extension 37 lits within the annular slot y40, seen in FIG. 6. The axial lower cylindrical end 39 is provided with inwardly and upwardly directed lingers 41 which lit within the apertures 34 thus securing the lower end 39 of the extension 37 to the anchor ring 27.
The extension 37 comprises for its major part an accordion pleated flexible rubberized fabric so that it can collapse into a relatively small vertical package. A vulcanized rubber fabric having reinforcing cords of nylon, polyester or rayon, for example, can be employed to fabricate the extension.
The top of the extension has an annular axial cylindrical portion 43 which may be of the same dimension and configuration as the bottom cylindrical portion 39. The top cylindrical portion 43 is provided with downwardly and inwardly directed fingers 44 which lock into apertures in the inner ring 45 of top ring 46. The top ring 46 may be identical in form to the anchoring ring 27 and is provided with an annular exterior chamber 48 secured to the inner ring 45 by central web 49. The charnber 48 is provided with valves 50 for infiation of the chamber or filling the same with liquid.
An upper extension, not shown, may be provided by mounting a ring in the upwardly opening slot 51. This may serve to prevent pollutants from splashing over exteriorly of the containing caisson. In many applications, however, a further extension of the caisson may not be required.
`In installation, the rings 46 and 27 are secured to the ends of the extensible extension 37 with the fingers 44 and 41 placed within the apertures in the internal rings 45 and 32, respectively. The chambers 48 and 30 may now be inflated and this causes the interior chamber wall to bear against the axial cylindrical end portions of the extension 37 tightly confining such end portions in the slot and, of course, the fingers in the apertures. This locks the ring to the extension and provides a substantially Iwater impermeable seal therebetween.
After the submerged foundation caisson 10 has been placed with the adaptor ring 22 thereon, the caisson extension is oated to a position above the caisson. The lower or anchor ring 27 may now be filled with water or ballast and the lower end of the extension dropped to fit onto the adaptor ring 22. As the lower ring drops, the extension axially expands. The locking fingers 25 are positioned within the apertures 26 and the chamber 30 may then be pressurized to provide a secure substantially watertight connection between the caisson extension 37 and the anchor caisson 10.
The axial cylindrical extensions 39 and 43 may be made of neoprene or rubber of a thickness greater than that of the pleated portion of the rubberized fabric therebetween. The locking fingers may be molded into such end portions and cotter pins connected together by a chain may be employed to ensure against disassembly. The top floating ring `46 may be anchored to the drilling platform inside the caisson to ensure against lateral drift.
In some installations it may be possible to omit the anchoring or footing caisson 10. In this case the bottom ring 27, suitably weighted or anchored, would simply rest on bottomi 11, its flexibility permitting substantial conformance thereto.
It can now be seen that there is provided an easily installed simplified caisson which includes a pliable, rubber fabric with floating or submersible collars which may readily be anchored to a submerged caisson to form a complete containment about an offshore well site. If oil or other contaminants spill into the water at the well site, they can be pumped or clam-shelled from within the caisson into a barge or like vessel alongside the caisson. The hydrostatic pressure balance can readily be maintained by pumping sea water into the inteiror of the caisson.
I, therefore, particularly point out and distinctly claim as my invention:
1. Apparatus for containing offshore well pollutants comprising an annular submerged caisson surrounding an offshore well point, and an annular extension of said caisson comprising an annular axially expansible water impermeable member secured at its lower end to the top of said caisson and extending to the waterline to form a liquid barrier surrounding such well point.
2. Apparatus as set forth in claim 1 including a fioating ring to which the top of said extension is secured.
3. Apparatus as set forth in claim 2 wherein said oating ring includes an inner vertical wall and an outer chamber, the top of said extension being positioned between said wall and chamber, and means to pressurize said chamber to squeeze the top of said extension between said chamber and wall.

5. Apparatus as set forth in claim 2 including a ring identical to said floating ring securing the lower end of said extension to said annular submerged caisson.
6. Apparatus as set forth in claim f1 wherein said annular extension comprises an accordion pleated rubberized fabric.
7. A method of containing offshore Well pollutants comprising the steps of forming an annular submerged caisson surrounding an offshore well point, oating a caisson extension into position over said caisson, axially downwardly extending such caisson extension and securing the lower end thereof to such caisson while maintaining the upper end thereof floating.
`8. Apparatus for containing offshore well pollutants comprising a cylinder which is axially collapsible and extensible, rings at the top and bottom of said cylinder, and chambers in said rings whereby the buoyancy of the top and bottom of said cylinder can be controlled.
9. Apparatus as set forth in claim 8 wherein the major extent of said cylinder is a flexible fabric having accordion pleats therein.
