  • embodiments disclosed herein relate generally to apparatuses and methods for loading and transporting large structures over bodies of water. Specifically, embodiments disclosed herein relate to a structure that may be disposed on a transport vessel, such as a barge, that enables larger structures to be transported on the transport vessel.
  • a transport vessel such as a barge
  • a large structure such as an oil platform or an oil rig, may be used to house machinery and/or workers used within the oil and gas industry to drill and/or extract oil and gas ⁇ i.e., hydrocarbons) through wells formed in the ocean bed.
  • This platform or oil rig depending on the environment and circumstances at the location of the hydrocarbons, may be attached to the ocean floor, may be formed as an artificial island, or may be floating at a desired location.
  • Offshore structures may be located on the continental shelf, though improvements in technology have enabled drilling and production of hydrocarbons in deeper waters and environments to be both feasible and profitable.
  • a typical offshore structure may then include around thirty wellheads located about the platform, in which directional drilling enables reservoirs to be accessed at both different depths and positions up to 10 kilometers away from the structure.
  • Offshore structures may be of various types, including fixed platforms, semi- submersibles, jack-ups, floating production systems ("FPSO's"), tension leg platforms, SPAR platforms, and others known to those skilled in the art.
  • FPSO's floating production systems
  • the "topsides" of the platform may generally refer to the surface hardware installed above the water.
  • Topsides may be modular in design, in which the topsides may be rearranged to enable expensive platforms to be readily updated with newer or different technology.
  • Typical topsides may range in size, such as from about 6,000 short tons to about 10,000 short tons (5440 metric tons to 9070 metric tons), depending on the size and needs of the project.
  • large transport vessels typically barges, may be used to transport the topsides from a construction yard on land to the desired offshore site. These topsides may then be transported in a single unit, or the topsides may be divided into portions for transport.
  • FIG. 1 shows a perspective side view of the transport vessel 100 with the skid beam assembly 1 10
  • Figure 2 shows a detail side view of a portion of the skid beam assembly 1 10.
  • the transport vessel 100 may include, for example, a barge or ship, on which the skid beam assembly 1 10 may then be placed and/or assembled to the deck of the transport vessel 100.
  • one or more support structures 140 may be placed on the deck of the transport vessel 100.
  • the skid beam assembly 1 10 may then be placed on top of the support structures 140. Because the deck of the transport vessel 100 may not be substantially flat and/or level, each of the support structures 140 may be individually adjusted, such as shimming the support structures 140. The support structures 140 may be adjusted to form a substantially flat and/or level surface to dispose the skid beam assembly 1 10 thereon. Otherwise, any non-level surfaces of the transport vessel 100 may affect the orientation of the skid beam assembly 1 10.
  • the skid beam assembly 1 10 is tapered, for example, longitudinally (from bow 102 to stern 104) along the length of the assembly 1 10.
  • the taper of the skid beam assembly 1 10 may be such that the height of the skid beam assembly 1 10 at the stern 104 of the transport vessel 100 is higher than the height of the skid beam assembly 1 10 at the bow 102 of the transport vessel 100.
  • the transport vessel 100 may have a lowered vertical center-of-gravity.
  • the skid beam assembly 1 10 may still be high enough at the stern 104 for loading and unloading the transport vessel 100, but may then also be lower in height at other portions of the transport vessel 100 to lower the vertical center-of-gravity of the skid beam assembly 1 10 and the transport vessel 100. By lowering the center-of-gravity, the transport vessel 100 may be more stable at transport and, therefore, sustain larger loads.
  • the taper of the skid beam assembly 1 10 may range from about 0.5 degrees to about 1.5 degrees, depending on the size of the topside to be disposed upon the skid beam assembly. Specifically, the upper surface of the skid beam assembly 1 10 may be disposed at an angle between about 0.5 degrees and 1.5 degrees with respect to the lower surface of the skid beam assembly 1 10. More particularly, the upper surface of the skid beam assembly 1 10 may be disposed at an angle of about 0.6 degrees to about 1 degrees with respect to the lower surface of the skid beam assembly 1 10. However, those having ordinary skill in the art will appreciate that the present disclosure is not so limited, and in other embodiments, the taper of the skid beam assembly may be disposed at an angle outside of the above described range. For example, in other embodiments, the taper of the skid beam assembly may be disposed at an angle between about 0.1 degrees and about 3.0 degrees.
  • the skid beam assembly 1 10 may be formed as one large structure, or may instead be formed in multiple portions assembled together. As shown, particularly in Figure 2, the skid beam assembly 1 10 may be formed as multiple portions 1 10A, 1 10B, in which each of the portions 1 10A, 1 10B may then be disposed on top of the support structures 140. If preferred, though not required, the skid beam assembly 1 10 may then be fixed to the support structures 140, for example, by welding or using mechanical fasteners, and/or the skid beam assembly portions 1 10A, 1 10B may be fixed to each other.

  • Figure 4 shows a top perspective view of the support structures 140 that support the skid beam assembly portion 1 10A.
  • the skid beam assembly portion 1 10A includes multiple beams 1 12 that run longitudinally when placed upon the transport vessel. These beams 1 12 of the skid beam assembly 1 10A may be intersected and supported by other support members 1 14 that run laterally (side-to-side across the transport vessel) when placed upon the transport vessel.
  • the support members 1 14 are rigidly attached to the beams 1 12, such as by welding, adhering, or mechanically fastening the support members 1 14 to the beams 112, such that the support members 1 14 may then distribute weight and forces evenly across the skid beam assembly portion 1 10A.

  • each support structure 140 may include one or more frames 142 and/or one or more base members 144.
  • support structures 140 may vary. Because support structures 140A, 140F have larger frames 142, these support structures 140A, 140F may be placed underneath ends A, F of the skid beam assembly portion 1 10A to provide the most support to the skid beam assembly portion 110A. Support structures 140C, 140D, which have additional base members 144 attached thereto, may then be placed underneath central locations C, D of the skid beam assembly portion 1 10A to provide support to the skid beam assembly portion 1 10A in the longitudinal direction.
