Abstract
The well intervention system is a subsea deployed wire line, 'stiff wire' (conventional wire-line located inside reeled tubing or embedded in the tubing wall), coil tubing, or reeled pipe unit landed on the existing subsea wellhead assembly or tree, wherein the unit includes as an additional novel component a 'carousel' tool caddy. The carousel is utilized to allow the remote change-out of multiple tool strings that are included in the carousel prior to deployment, thereby eliminating the need for a 'riser' conduit to the surface or the need to trip tools through the riser column for tool replacement. A method for conducting a well intervention activity, wherein the method includes the step of selecting a tool for the well intervention activity from a carousel tool caddy located in close proximity to the well. The invention system may also be employed in a similar manner to conduct repair or surveillance operations for pipelines or flowlines having flow control manifolds.
