Definitions

  • SPM terminals Single Point Mooring terminals
  • SPM terminals are well documented and described in many patents and patent applications world-wide. Many types of SPM terminals have been developed to cater for specific conditions at a given location; many such systems cannot be re-used at other locations due to this, nor is this always desired.
  • This disclosure describes a SPM terminal designed primarily to overcome problems encountered in traditional SPM systems when high currents and very large tidal variations are encountered. Applications in other areas are also possible.
  • SPM terminals employ submarine hose configurations to convey products between the terminal itself and the seabed pipeline.
  • submarine configuration may no longer be safely accommodated.
  • the invention provides a single point mooring floating terminal including a leg for connection to a seabed anchorage, the anchorage including a base for location on the seabed and means to connect the lower end of the leg to the base to allow the leg to rise and fall and to tilt with the tide/current to which the terminal is subjected.
  • An anchoring base 1 is installed on the seabed by means of piles 2 or alternatively by ballasting.
  • the base may be designed such that it could serve also as a transport barge for the entire SPM system, allowing the system to be self installable by selected flooding of the base compartment.
  • a structure 3 is fitted on top of the base which supports hinges 4. These hinges in turn support a mooring yoke 5.
  • the other end of the mooring yoke is fitted to one or more nominally vertical tension legs 6 by means of a universal joint 7. This tension leg may consist of rigid or flexible elements.
  • the yoke is fitted with ballast 8 near this universal joint.
  • the vertical tension leg is supported from a floating buoy 9 through the intermediary of a universal joint 10.
  • the floating buoy may be of the type known in the industry as “turret” type or “turntable” type. Although different shapes, such as tall, cylindrical shapes may also be used.
  • the buoy is equipped with a mooring lug and piping such that tankers may readily moor to it by means of a hawser and a floating hose.
  • a combination of jumper hoses 11 and hard piping 12 is employed to convey the fluids between the piping on the buoy and the seabed pipeline 13.
