Abstract: The invention relates to a connector (1) for clamping a component around a tubular member (30) and to a method of using such a connector. The clamping connector (1) comprises a collar (2), a plurality of movable dogs (16) mounted in the collar and actuation means for driving the movement of the dogs. The collar (2) has an inner wall (4) and an outer wall 5, the inner wall being adapted to surround the tubular member (30) with a gap (56) between an outer surface of the inner wall (4) and an outer surface (28) of the tubular member. The inner wall (4) has a plurality of apertures (12) each aperture leading to a passage (14) through the inner wall. Each of the dogs (16) is slidably seated in one of the passages (14) for movement in a radial direction with respect to the tubular member (30). Around each passage (14) the inner wall (4) is spaced apart from an inner surface (25) of the outer wall (5).

Abstract: The disclosure relates to a connector assembly (20) for joining a main tower (102) to a base structure (114) where the axial alignment of the tower to the base structure needs to be adjustable, and to a method of using such a connector assembly to assemble a tower structure.

Abstract: A tension ring lifting assembly (101) for securing around a pipe, the assembly comprising a tension ring (112) and at least one lifting lug (130) by which the tension ring, and a pipe around which the tension ring has been secured, can be lifted. The tension ring comprises: a plurality of collar segments (114, 116) which can be assembled into a ring around the pipe; a plurality of slip segments (140) adapted to fit between the collar segments and the pipe and to make direct contact with the pipe surface, the collar segments and the slip segments when assembled having inclined contacting surfaces such that an inner diameter across said assembled ring, between the inner faces of the collar segments, varies as the segments move up and down in the collar; means for tensioning (152, 154, 156) adjacent collar segments (114, 116) against one another to secure said ring around the pipe; and means for removeably mounting (7, 9) said at least one lifting lug (130) to the tension ring (140).

Abstract: The present invention provides an apparatus for launching spheres into a gas riser in order to reduce the risk that the output from the riser is lost. The apparatus comprises a rotatable body that is rotated to a first position to receive an object from an object storage means in an aperture and the rotatable body is then rotated to a second position such that the object received in the aperture is received within a riser.

Abstract: A connector for underwater connection of two fluid carrying conduits comprises initial engagement means to provide an initial engagement between a male component and a female receptacle. The final connection is made by operating a drive which reacts against the initial engagement means to move the component into a fully connected position. A number of sealing means may be provided to enable a pressure tight connection.
