Abstract:
An apparatus including an external surface portion shaped so as to mate with a docking device, and two half-shells having internal surfaces of semi-circular cross section. The apparatus further includes a plurality of segments arranged inside the two half-shells and including teeth for gripping onto a shaft, and an installation tool operable to cause the two half-shells to close around the shaft, thereby securing the apparatus to the shaft.

Claim (Index 48):
A method of repairing a shaft, such as a subsea riser, for use in the oil industry, the method comprising:\n cutting through the shaft at a pre-determined location, resulting in a first shaft section and a second shaft section; attaching a gripper unit apparatus onto the first shaft section, the gripper unit apparatus protruding from the first shaft section; landing an alignment and installation apparatus onto said gripper unit apparatus, the alignment and installation apparatus carrying a component to be installed on the cut end of the first shaft section, wherein the component is a connector for connecting the first shaft section to a flexible pipe; pitching and rotating the alignment and installation apparatus to align an axis of the connector with the axis of the first shaft section; contracting the alignment and installation apparatus, thereby translating the connector substantially along the axis of the first shaft section until the cut end of the first shaft section is positioned on or within the connector; and activating the connector to secure it onto the first shaft section, thereby enabling the communication of fluids between the flexible pipe and the first shaft section.
