Abstract:
1. A subsea intervention system for lowering a selected tool from a plurality of stored subsea tools through a subsea blowout preventor having a BOP axis and into a well on coiled string and for selectively withdrawing the tool from the well through the subsea blowout preventor and returning the selected tool to the plurality of the subsea tools, the system comprising: a subsea injector for moving the coiled string axially through the blowout preventor: one or more strippers for sealing with the axially moving string; a tool positioning system for moving the selected tool in a first linear direction substantially perpendicular to the BOP axis to a run-in position wherein the selected tool is above the blowout preventor with a tool axis substantially aligned with the BOP axis; and an injector positioning system for moving the injector from a run-in position wherein the injector is above the blowout preventor and an injector axis is substantially aligned with the BOP axis, to an inactive position for allowing the selected tool to occupy at least a portion of the BOP axis occupied by the injector when in the run-in position.
