Definitions

  • This invention relates to a flow line system for use in the transfer of fluid to or from under water sites.
  • a flow line system for use in the transfer of fluid to or from an under water site, the system comprising a first, flow line arrangement to be installed so as to extend from the water bed to near, but below, the surface, this arrangement being carried by a buoyant support column that is for articulated connection to the water bed and that consists of rigid sections that are connected in series at articulated connections so that the first flow line arrangement is rigidly supported by - each section but can articulate at the base of the column and at the connections between the rigid sections; and a second, flexible, flow line arrangement releasably connectable to the first arrangement, where the first arrangement terminates near the surface, so as to extend the first arrangement.
  • Such a system can be installed between a wall head, manifold or other convenient location at the water bed and production facilities at the surface with the advantage that the connection between the first and second flow line arrangements is near the surface and hence readily accessible.
  • the articulated connections at the water bed and between the rigid sections, with the otherwise rigidly supported first flow line arrangement able to articulate with the support column at these connections enables the system as a whole to cope with extensive movement of floating facilities at the surface so that the system is suitable for use at considerable depths (extent of surface movement increases with water depth).
  • the suitability for use at considerable depth is enhanced by the provision of articulation of the column and the first flow line arrangement as this gives to the column and the flow line arrangement it supports good ability to absorb lateral loads and impacts.
  • the column can be made slim which facilitates its handling during installation and removal.
  • Figure 1 a flow line system between a sea bed well head and production facilities provided on a semi-submersible production platform.
  • Figure 2 shows on a larger scale the detail ringed at II in Figure 1.
  • the semi-submersible production platform 1 is shown in position over the sea bed well head 2 with workover guidelines 3 extending between the platform and the well head.
  • a sea bed anchorage structure 4 to which is anchored, by an articulated connection 5, a series of buoyed rigid column sections 6.
  • the column sections 6 are connected to one another in series at articulated connections 5A, and each section incorporates a buoy 13 at its upper end.
  • the articulated connections can be of any suitable construction as known in the art giving freedom of movement about two mutually perpendicular axes.
  • the column made-up by the sections 6 rigidly supports between the connections 5A a first flow line arrangement 7. One part of this first flow line arrangement 7 is connected to flow lines 8 from the well head 2.
  • connection 5A there is an articulated connection 12 in the flow line arrangement 7 and this arrangement can also articulate at the base of the column.
  • the flow line arrangement 7 is rigidly supported by the buoyed column sections 6 but can articulate at the base of the column and at the connections between the column sections.
  • the articulated connections in the flow line arrangement 7 are effected by flexible flow line portions 12A interconnecting the otherwise rigid runs of the flow line.
  • the column terminates near, but below, the surface of the sea, and at this termination the first articulated flow line arrangement 7 is releasably connected to a second, flexible, flow line arrangement 10.
  • This second flow line arrangement 10 extends to the production platform 1, to which it is releasably connected, and serves for supply to, and export from, the production facilities.
  • the semi-submersible platform 1 can be held on station by a conventional mooring system or by an automatic jack mooring system, the inclusion of the flexible flow line arrangement allowing movement of the platform to take place within a predetermined range.
  • the automatic jack mooring system can utilise the top of the column as a reference point for locating the platform.
  • a flexible flow line arrangement is required to accommodate motion of the floating platform, but to have the flexible flow line arrangement extending, for example, all the way to the water bed could result in a flexible flow line arrangement of such considerable length and consequent weight as to introduce problems in, for example, recovery thereof after disconnection from the well head.
  • an articulated but otherwise rigidly supported flow line arrangement terminating below surface level adverse effects of wave action, lateral loads and impacts on this arrangement and its support (the column) are avoided or readily absorbed.
  • connection 5 at the base of the column is releasable, along with flow line connections to the flow lines 8 and 9, but in the system shown all the connections 5A and 12 are releasable as well.
  • the flexible flow line arrangement 10 is provided with buoyancy 11 to cushion the movement of the flexible flow line, especially when it is disconnected in an emergency.
  • the flexible flow line arrangement 10 also avoids a need for providing tensioning equipment on the floating platform, as is necessary in constructions where a tensioned riser flow line arrangement is provided between a well head and a floating production platform. Also loading on the production platform is reduced as compared with a tensioned flow line arrangement.
  • the illustrated form also has the advantage that the flow line arrangements are disposed to one end of the floating platform, leaving the central moonpool of the platform free for working over the well head. Workover relative to the flow line arrangements is via a separate derrick mounted over the flow line arrangements.
  • the flexible flow line arrangement 10 need not necessarily be connected to floating facilities, and the facilities to which it is connected could be other than production facilities.
  • the buoyancy for the column sections 6 can be built-in along the length of each section, rather than provided by the buoys 13.
