Definitions

  • Bottom supported mobile offshore drilling units such as "jack up" rigs are known in the art for use in plugging and abandonment procedures for wells drilled beneath a body of water.
  • a jack up rig drilling may be moved to a location of a production platform such as a bottom supported platform.
  • the jack up hull is raised out of the water by jacking support legs coupled to the hull of the drilling unit the hull is raised to a selected elevation above the water surface.
  • a cantilever structure comprising a drilling unit may be extended from a retracted position over the hull to an extended position over a recess in the profile of the hull and over the production platform.
  • the cantilever structure 10D may comprise only the drilling unit 10B prior to refitting the MOSP 10 to be usable with methods according to the present disclosure.
  • the MOSP 10 may be a conventional "jack up" type mobile offshore drilling unit having a drilling unit 10B on the cantilever structure 10D but excludes a crane on the cantilever structure 10D (although other components explained below may be present on such a cantilever structure).
  • the cantilever structure 10D may have a crane, e.g., as shown at IOC attached to the existing cantilever structure 10D at a shipyard or similar facility.
  • FIG. 2 shows a side elevation view of the MOSP 10 wherein the cantilever structure 10D is retracted partially from its extended position. In such position, the drilling unit 10B mast or derrick may be lowered, for example, by retraction of a vertically telescoping mast structure to provide additional working clearance for the crane IOC.
