Abstract: An offshore well is stabilized by at least three cables connected on one end to hydraulically powered cable tensions on the well casing at a location substantially below the surface of the body of water in which the well is located and on an opposite end to a respective anchor pile on the bottom body of water. The cables are equally tensioned by the hydraulically powered cylinder and are subsequently retained in taut condition by mechanical retainers.

Abstract: A wellhead and conductor pipe supported by a cable and anchor system is disclosed which is comprised of a plurality of anchor cables secured to the conductor at a first end of each cable, the second end of each cable being fixed to an anchor pile in a surrounding land formation beneath a body of water. In preferred embodiments the cables are secured to the conductor by means of an annular brace having an upper collar portion to which the first end of each cable is attached and a lower collar portion having pulleys mounted thereon and around which the cables are journalled. Anchor piles are driven into the subsea land formation by releasably securing an anchor pile to a drive pile and exerting a downward force on the drive pile to drive the anchor pile into anchoring engagement with the formation below the mud line.

Abstract: An escape apparatus for elevated structures, such as multi-story buildings, offshore platforms and the like. An elongated pole is pivotally connected to the elevated structure to move between a stored position, in substantial alignment with a horizontal level of the structure, and a ready, substantially vertical position. A person escapes the elevated structure by sliding down the vertically positioned pole.
