1. An apparatus for overhauling a flanged coupling of joined conduit components, the apparatus comprising:
a lifting frame having a gripping mechanism operatively mounted thereon, wherein the gripping mechanism is configured to straddle the flanged coupling and to grip both of said joined conduit components, wherein the lifting frame is adapted to support the joined conduit components gripped by the gripping mechanism during lifting of the joined conduit components to prevent loading on the flanged coupling; a base frame adapted to be installed upon the seabed to rest on the seabed to receive and support joined conduit components for overhaul from the lifting frame and wherein said base frame comprises a support to receive the joined conduit components when the lifting frame is coupled with the base frame and a collar sized to fit over the flanged coupling and located in spaced apart cradles supported upon the base frame, wherein said cradles are configured to receive the joined conduit components and to position the collar for closure about the flanged coupling, wherein the collar is provided with fasteners for closure of the collar about the flanged coupling, and a fastening mechanism adapted to operate the fasteners to secure the collar when closed about the flanged coupling; wherein the lifting frame and the base frame have a releasable coupling such that the lifting frame is located on the base frame when the lifting frame and the base frame are coupled and such that the lifting frame and the base frame are not connected to each other when the lifting frame and the base frame are uncoupled. |
