Definitions

  • Oil producers use offshore platforms to support subsea oil wells.
  • coiled tubing jobs are performed on the offshore platform.
  • the coiled tubing is unspooled from a reel and injected through a rig floor via a coiled tubing injector hanging in a derrick.
  • the coiled tubing reel must be placed in position so that a line of sight is maintained along the coiled tubing as it moves through a door in the rig floor.
  • the line of sight requirement can create a variety of problems related to utilization of the offshore platform and completion of the coiled tubing job. For example, crane capability and lift radii restrictions often prevent placement of the heavy reel in an optimum position on the offshore platform. Additionally, placement of rig components, such as automated pipe handling systems and elevated catwalks, can be difficult without blocking the line of sight. Often, large deck areas of the offshore rig must be segregated with barriers during a coiled tubing job due to movement of the coiled tubing pipe overhead. As a result, rig operations and crane lifts are restricted. Because of the limitations on placement of the coiled tubing reel and other components, small radius goosenecks are sometimes necessary to direct the coiled tubing along a desired route. However, use of small radius goosenecks often detrimentally impacts the low cycle fatigue resistance of the coiled tubing.
  • the present disclosure provides a system and methodology for facilitating coiled tubing operations in offshore environments.
  • the system and methodology employ a spooled device disposed on a reel which is located on an offshore facility.
  • a guide system is mounted on the offshore facility to guide the spooled device from the reel, along a desired path, and down through a floor of the offshore facility.
  • the guide system enables the coiled tubing job to be conducted without requiring a line of sight along the coiled tubing as it is delivered down through the offshore facility.
  • the present disclosure generally relates to a system and method for facilitating offshore well operations in which a spooled device is deployed from a surface facility.
  • the technique enhances the efficient and safe use of a surface facility, e.g. an offshore platform/rig, a semi submersible rig, a monohull vessel, when deploying the spooled device to a subsea well or other location.
  • the spooled device may comprise coiled tubing, wireline, slickline, or other spoolable device which is deployed from a reel.
  • a guide system is mounted on the offshore facility to deliver the coiled tubing or other spooled device along a predetermined route in a manner which does not require "line of sight” control over the spooled device as it is delivered down through the offshore facility to a subsea wellhead or other subsea installation.
  • the guide system is designed according to the size, shape, and components of the offshore facility.
  • the guide system comprises a tubular guide, such as a pipe, e.g. steel pipe, through which the spooled device is routed.
  • the tubular guide is designed with large radius curves to reduce or eliminate the fatigue otherwise experienced by certain spooled devices, such as coiled tubing.
  • the guide system may be a continuous guide which fully encloses the route along which the coiled tubing is delivered from the coiled tubing reel to a location proximate a floor of the offshore facility. In other embodiments, however, the guide system may be intermittent such that the coiled tubing or other spooled device extends through open regions between tubular sections of the guide system.
  • the guide system is permanently installed on the offshore facility.
  • the guide system may be mounted during construction of the offshore facility, thus enabling the guide system to be fully integrated and fitted into the derrick and/or other components of the offshore facility.
  • the guide system may incorporate additional components, such as mechanisms to grip and hold the coiled tubing (or other spooled device) at either end of the guide to increase rig up efficiency.
  • the guide system also may incorporate swivels, extensions, flexible sections, lubricants, trumpet ends, roller guides, and other components designed to facilitate movement of the coiled tubing (or other spooled device) along the guide system during operation.
  • the reel e.g. coiled tubing reel
  • the reel may be placed in a variety of convenient locations, such as a lower deck location of an offshore platform.
  • the guide system may be used to route the coiled tubing in a manner that does not interfere with pipe handling systems, elevated catwalks, and other components of the offshore facility.
  • the guide system can free up large deck areas of the offshore facility by removing the need to create barrier regions which can restrict rig operations and crane lifts.
  • an embodiment of an offshore system 20 is illustrated as having a guide system 22 incorporated into an offshore facility 24.
  • the offshore facility 24 may comprise an offshore platform/rig, a semi submersible rig, a monohull vessel, or other offshore facility; however Figure 1 illustrates an example of an offshore platform/rig.
  • the offshore facility 24 comprises a plurality of decks 26 located at different levels to enclose components or to provide surface area for a variety of components.
  • the offshore facility 24 comprises a plurality of cranes 28 which are used to move components onto, off, and around the offshore facility.

  • reel 32 is located on a lower deck 36 of the plurality of decks 26.
  • the lower deck 36 of this embodiment comprises a cantilevered pipedeck and is positioned beneath an upper deck/pedestal 38 on which derrick 30 is mounted.
  • the reel 32 may be positioned in a variety of other convenient locations on the offshore facility 24.
  • the reel 32 may be positioned so that coiled tubing 40 (or other spooled device) is spooled off the lower side of reel 32 rather than over the top of the reel.
  • the coiled tubing 40 is delivered from reel 32 into a tubular guide 42, e.g. a pipe section, of guide system 22.
  • guide system 22 may use tubular guide 42 in the form of one or more pipe sections which extend continuously or with interrupted segments from reel 32 through a bottom end of derrick 30 or to another desired exit location.
  • the pipe sections of guide system 22 are constructed of suitably sized sections of pipe, e.g. steel pipe, with each section having a desired diameter and length.
  • the tubular guide 42 has an outside diameter of approximately 5 inches, which is suitable for many types of coiled tubing and other spooled devices 40.
  • the one or more pipe sections 42 also may be connected via flanges, e.g. ANSI 150 pound flanges, or other suitable connectors.
  • guide system 22 may employ a series of elongated pipe sections 42 arranged along a designated path through which the spooled device, e.g. coiled tubing 40, travels from the reel 32 to a coiled tubing injector head. If the spooled device is not coiled tubing, e.g. slickline cable or wireline cable, then the tubing injector head is not necessary.
  • the guide system 22 is formed from suitable materials, e.g. stainless steel, which prevent corrosion and ensure a low coefficient of friction as the spooled device 40 passes through the guide system 22. Internal surfaces of the pipe sections 42 may be prepared with low coefficient of friction coatings, lubricants, rollers, or other mechanisms to facilitate movement of the spooled device. To further facilitate consistent, easy movement of the coiled tubing or other spooled device 40, the guide system 22 may be permanently installed on the offshore facility during, for example, the original build phase. The predesigned, permanent installation enables guide system 22 to be fully integrated and fitted into the derrick 30 during construction.

  • pipe section 42 of guide system 22 extends from under the cantilever at a position beneath the upper deck or pedestal on which the derrick 30 is mounted. From this lower location of reel 32, the pipe section 42 curves upwardly and runs straight along a corner 46 of the derrick 30 until gently curving inwardly toward a central region of the derrick 30. The pipe section 42 then curves downwardly to a position which enables deployment of coiled tubing 40 through a floor opening of the offshore facility 24.
  • the guide system 22 is lubricated.
  • lubricant may be placed along the interior of the one or more pipe sections 42 by injecting suitable fluid/chemical products into the guide system.
  • the guide system 22 and tubular guide 42 also may be designed to provide secondary fluid containment in the event of a rupture, e.g. a pinhole or pipe separation.
