McMiles - Web page: https://patentgrep.com/patent/US8540029B2 ## CPC - E21B 17/01: Risers - E21B: EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS ## Abstract A clamp for securing about annular casing via a centrally oriented aperture having a radius includes at least one aperture for grasping a longitudinally extending accessory disposed about the radius of the centrally oriented aperture and at least one fastening member for securing the longitudinally extending accessory about the clamp. At least one fastening member and at least one aperture act to secure a longitudinally extending accessory relative to the annular casing. ## Claims ### Claim 1 A clamp for securing about an annular casing via a centrally oriented aperture having a radius comprising: a generally planar body having a central aperture and a plurality of radial extensions for placement around a riser pipe independent of and between sections of floatation positioned around said riser pipe; said extensions each partially engaging one end of said floatation across a flat surface of said extensions; at least one of said extensions having a pivotable line clamp for releasably grasping a longitudinally extending accessory disposed bout the radius of the centrally oriented aperture; and said line clamp is retracted within an outer periphery of the floatation and extended beyond the outer periphery of the floatation when engaged with said longitudinal extending accessory. ### Claim 2 (depends on 1) The clamp for securing about annular casing via a centrally oriented aperture of claim 1 wherein said line clamp may be retracted to permit longitudinal removal of said clamp from said pipe while engaged with said riser pipe. ### Claim 3 (depends on 1) The clamp for securing about annular casing via a centrally oriented aperture of claim 1, wherein said clamp is positioned adjacent said floatation. ### Claim 4 (depends on 1) The clamp for securing about annular casing via a centrally oriented aperture of claim 1, wherein a portion of the clamp is capable of circumferentially releasing one or more longitudinally extending accessories. ### Claim 5 (depends on 1) The clamp for securing about annular casing via a circumferentially oriented aperture of claim 1, wherein a portion of the clamp is capable of removably detaching from the annular casing to release a single longitudinally extending member while coupling another longitudinally extending member. ### Claim 6 A clamp for securing about annul casing via a centrally oriented aperture having a radius comprising: a generally planar body having a central aperture and a plurality of radial extensions for placement about a riser pipe and between riser floats on said riser pipe; said extensions each partially engaging one end of said floatation across a flat surface of said extensions; at least one of said extensions having a releasable pivotable line clamp for grasping a longitudinally extending accessory disposed about the radius of the centrally oriented aperture; and said line clamp is retracted within an outer periphery of the floatation and extended beyond the outer periphery of the floatation when engaged with said longitudinal extending accessory. ### Claim 7 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6 wherein said clamp supports at least one riser float. ### Claim 8 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6 wherein said line clamp is comprised of two opposing pivoting members capable of an open and closed position. ### Claim 9 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6 wherein said clamp is independent and not contained within said riser float. ### Claim 10 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6 wherein said clamp is positioned between two riser floats. ### Claim 11 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6 wherein said line clamp may be retracted to permit longitudinal removal of said clamp from said pipe while engaged with said riser pipe. ### Claim 12 (depends on 6) The clamp for securing about annular casing via a centrally oriented aperture of claim 6, wherein a portion of the clamp is capable of circumferentially releasing one or more longitudinally extending accessories. ### Claim 13 (depends on 6) The clamp for securing about annular casing via a circumferentially oriented aperture of claim 6, wherein a portion of the clamp is capable of removably detaching from the annular casing to release a single longitudinally extending member while coupling another longitudinally extending member. ### Claim 14 A clamp for securing about annular casing via a centrally oriented aperture having a radius comprising: a generally planar body having a central aperture and a plurality of radial extensions for placement around a riser pipe, said body independent and adjacent at least one riser float about said riser pipe; at least one of said extensions having a releasable two-part pivotable line clamp for grasping a longitudinally extending accessory disposed about the radius of the centrally oriented aperture; said extensions each partially engaging one end of said floatation across a flat surface of said extensions; and said line clamp is retracted within an outer periphery of the floatation and extended beyond the outer periphery of the floatation when engaged with said longitudinal extending accessory. ### Claim 15 (depends on 14) The clamp for securing about annular casing via a centrally oriented aperture of claim 14 wherein a portion of the clamp is capable of circumferentially releasing one or more longitudinally extending accessories. ### Claim 16 (depends on 14) The clamp for securing about annular casing via a centrally oriented aperture of claim 14 wherein said clamp is not contained within said riser float. ### Claim 17 (depends on 14) The clamp for securing about annular casing via a centrally oriented aperture of claim 14 wherein said line clamp is comprised of opposing pivotable members.
