ABSTRACT:
A coupling 10 for connecting an elongate first member 12 to a second member 14. The first member 12 is provided with external radial fins 16. The second member 14 defines a recess provided with a number of internal radial fins 20. The first and second members 12,14 and their fins 16,20 are sized such that the first member 12 can be positioned within the recess of the second member 14 with each fin of each member extending between two corresponding fins of the other member. At least one wedge 24 is positioned in the space intermediate each set of opposing fins 16,20. The fins 16,20 and wedge 24 are configured such that biasing the first member 12 in a first axial direction relative to the second member 14 causes the wedge 24 to lock the fins 16,20 together, preventing movement of the first member 12 in the first axial direction. The present coupling 10 can be used to support the members 12,14 under either a tensile or compressive axial loading. The coupling 10 is especially well suited for adjustably connecting a tension leg offshore platform to the tethers securing it to the seafloor.
