Definitions

  • This invention is generally related to a military logistics base and more particularly to a mobile base offshore.
  • the floating airfield comprises a number of individual barge sections, which are articulately coupled to neighbouring sections to provide a suitably sized airfield. Welded fenders on the hull at the bow and stern of each barge section keep the neighbouring sections apart to prevent collision whilst also providing the means for connecting the barges' sections together to form a suitable length of runway. Directing the floating airfield in the wind direction and anchoring in place provides a stable structure.
  • WO 97 10989 provides a multi-hull work platform comprising an above-water portion and an under-water portion consisting of two hull sections.
  • Each hull section consists of one or more pontoons, which are totally submerged and whose length is greater than the length of the above-water portion.
  • Each pontoon is connected to the above-water portion by at least one longitudinal web having a small water plane area.
  • the present invention provides a floating mobile offshore base comprising a plurality of single base units connected together, each of said single base units comprising:
  • a suitable mobile offshore base is formed from several individual single base units that are connected together at sea to form the complete base.
  • the complete base forms a runway and support base for fixed wing and rotary wing aircraft and also provides space for stowage and transport of equipment and personnel.
  • the single base units are similar semi-submersible units that are linked together by hinges and/or U-joints to form the complete mobile offshore base.
  • Each single base unit is self-propelled and is also capable of independent operations at widely separated locations.
  • the single base units are each formed from lower hulls, columns that extend upward from the lower hulls, and an upper hull attached to the columns.
  • Mobile offshore base 10 is formed from a number of single base units 12 that are connected together at sea.
  • Each single base unit 12 is generally comprised of at least two buoyant lower hulls 14, columns 16, and upper hull 18.
  • lower hulls 14 are preferably ship shaped (streamlined with symetrically faired bow and stern shapes) to allow for movement at transit and operating speeds at the efficient power and propulsion capabilities.
  • Propulsion and dynamic positioning thrusters are indicated by numeral 20.
  • Columns 16 are illustrated as being square or rectangular in section but may be of any suitable shape.
  • Upper hull 18 is rigidly attached to the upper end of columns 16 adjacent outer opposing sides of upper hull 18 such that lower hulls are spaced across the width of the upper hull and are parallel to the longitudinal axis of the upper hull.
  • Bracing 22 rigidly attached between columns 16 and upper hull 18 provides support to minimize flexing and maintain spacing between the lower hulls 14.
  • Upper hull 18 is sized and constructed to form an upper deck 24 and, in the configuration illustrated, three lower decks 26.
  • Upper deck 24 serves as an aircraft runway and landing area for fixed and rotary wing aircraft as well an apron for loading and unloading the aircraft.
  • Lower decks 26 are used for living space and storage space for equipment and supplies.
  • Fig. 3 illustrates loading and storage capabilities.
  • Each single base unit 12 is provided with variable ballast tanks 28 in lower hulls 14 and columns 16.
  • Variable ballast tanks 28 provide for operation as a semi-submersible vessel to selectively allow operation at different drafts.
  • the hulls 14 are at their shallowest draft and allow for top speed.
  • lower hulls 14 are fully submerged below the water surface to provide, relative to transit draft, a smaller water plane area through hull that greatly reduces pitch, roll, and heave in response to wave action. Survival draft is selected during storms.
  • Variable ballast tanks 28 are operated to receive or expell water ballast in a manner well known in the art.
  • each single base unit 12 may be used individually or one or more may be connected together as illustrated in Fig. 4 to form a mobile offshore base suitable for receiving fixed and rotary wing aircraft.
  • the connected units are preferably ballasted to an operational draft as illustrated to minimize motions from waves.
  • each individual unit 12 is designed to be three hundred meters in length, one hundred fifty-two meters in breath at the flight deck, and seventy-five point six meters tall.
  • each lower hull 14 is two hundred seventy meters long, thirty-eight meters wide, and sixteen meters tall, with symetrically faired bow and stern shapes.
  • the transit draft is expected to be between thirteen and fourteen meters.
  • the operational draft is expected to be thirty-eight meters and the survival draft is expected to be thirty-five meters.
  • Special marine connectors 30, seen in Fig. 1 are used to connect the units by means of hinges and/or U-joints. Special connectors are required due to the large loads encountered. Such special connectors are the subject of copending application Serial Number 08/XXX,XXX filed July 31, 1997, publication number US 5 988 932.
