Abstract
An apparatus for stabilizing a conduit, such as a riser, against motion. The apparatus comprises an outer wall portion, an inner tubular member having a longitudinal channel extending therethrough, a first tubular member at least partially located between the outer wall portion and the inner tubular member, and a second tubular member at least partially located between the outer wall portion and the inner tubular member. The outer wall portion at least partially surrounds the inner tubular member and the first and second tubular members are movable about the inner tubular member and are movable relative to each other. The first and second tubular members are adapted for securing to the conduit, such as a riser.
Claims21
An apparatus for stabilizing a conduit against motion, the apparatus comprising:
- a first cylinder assembly comprising a first outer wall and a first movable member slidably positioned within the first outer wall, wherein an end of the first movable member is adapted for connection with a portion of the conduit;
- and
- a second cylinder assembly comprising a second outer wall and a second movable member slidably positioned within the second outer wall, wherein an end of the second movable member is adapted for connection with another portion of the conduit;
- a central tubular member having an axial bore extending therethrough, wherein the first and second movable members are concentrically positioned about the central tubular member, wherein the first and second movable members are slidable about the central tubular member, wherein the first outer wall is spaced from the central tubular member to form a first annular space therebetween, wherein the second outer wall is spaced from the central tubular member to form a second annular space therebetween, wherein the apparatus comprises a first fluid port for communicating a fluid into and out of the first annular space, the second annular space, or combinations thereof.
An apparatus for stabilizing a conduit against motion, the apparatus comprising:
- an outer wall portion;
- an inner tubular member having a longitudinal channel extending therethrough, wherein the outer wall portion at least partially surrounds the inner tubular member;
- a first tubular member at least partially located between the outer wall portion and the inner tubular member, wherein the first tubular member is movable about the inner tubular member, wherein the first tubular member is adapted for securing to the conduit;
- and
- a second tubular member at least partially located between the outer wall portion and the inner tubular member, wherein the second tubular member is movable about the inner tubular member, wherein the first and the second tubular members are movable relative to each other, wherein the first tubular member is adapted for securing to the conduit.
The apparatus of claim 24, wherein the first fluid port communicates fluid into a central space located between the inner tubular member and the outer wall portion.
An apparatus for stabilizing a conduit against motion, the apparatus comprising:
- a housing assembly;
- an internal tubular member having a longitudinal channel extending therethrough, wherein the internal tubular member is at least partially positioned within the housing assembly forming an annular space therebetween, wherein the housing assembly includes at least one fluid port for communicating a fluid into and out of the annular space;
- a first movable tubular member positioned concentrically about the internal tubular member, wherein the first movable tubular member is slidable about the internal tubular member;
- and
- a second movable tubular member positioned concentrically about the internal tubular member, wherein the second movable tubular member is slidable about the internal tubular member, wherein the first movable tubular member and the second movable tubular member are movable relative to each other, wherein the first and second movable tubular members are adapted for securing to the conduit.
