Definitions

  • the vessel employed in the first aspect of the invention is a submersible catamaran having two floats disposed generally parallel to and spaced apart from each other.
  • the second aspect of the invention also relates to the catamaran of claim 19 which includes a gantry to be constructed according to the method of claim 18.
  • the third aspect of the invention also relates to a method for picking up a topsides for decommissioning using a load lifting system which is integral to the vessel, carrying the topsides and redepositing the topsides using the same lifting system.
  • the vessel is a catamaran having spaced parallel floats and a support surface across the top of the floats and spanning the gap between the floats, wherein said support surface in the area of the gap is partly formed by a buoyant hatch, which is hatch is removable from the support surface and is adapted to be secured to said crane to render the crane floating.
  • FIG 15 shows the floating A-frame secured to the stern of the catamaran .
  • the first and second submersible floats (8) and (10) are disposed in a parallel relation to each other along a center line (158) .
  • the first float tail (58) and the second float tail (60) have a tapered shape. Alternatively they can be of a rectangular design, however the tapered shape enables easier positioning of the catamaran when engaging objects at sea.
  • the two hulls and the columns are rigidly interconnected by the support surface (12) .
  • the towers or columns can contain propulsion and control mechanisms, crew accommodation and other equipment, such as ROV's, diver work chambers, pipeline repair gear or other operating equipment .
  • FIG 2 shows one of the two fixed columns, the first fixed column (18) disposed on the submersible float (8).
  • FIG 5 shows the way in which the catamaran can be submerged to at least 3 different draft depths.
  • the first depth is shown as reference numeral (180)
  • the second depth is shown as reference numeral (182)
  • the third depth is shown at reference numeral
  • Figure 6 shows one element of the vertical positioning system (24) which is installed in at least two of the moveable columns and used for securing the catamaran to an object at sea.
  • a first line (134) connects to an object at sea (1000) .
  • One end of this line (134) is secured substantially vertically to an object at sea (1000) .
  • the angle of attachment is usually not more than between 5 and 30 degrees from the vertical.
  • a second line (135) is used, as shown in FIG 7 and is also secured on one end, substantially vertically, no more than between 5 and 30 degrees from the vertical, to the same object at sea.
  • FIG 18 shows the catamaran at a normal draft for transport of the jacket (1000) ; however, the catamaran can submerge slightly in order that the deballasting of the vessel and the structure of the gantry to minimize vessel movements.
  • One specific method of using the erected gantry contemplates submerging the catamaran while positioned around the jacket or object at sea, attaching the lifts to the top most portion of the jacket. Tensioning the lifting lines. Attaching to the object at sea, the horizontal and vertical positioning lines which are secured to the motion compensation systems located in each of the moveable load supporting columns .
  • FIG 24 shows a crane (430) secured to the center of the catamaran (2) for lifting objects at sea.
  • FIG 25 shows how that same crane (430) can be moved to a different position on the catamaran using the floatable hatches.
  • two floatable hatches can be used, (438) and (440) to slightly elevate the crane while the catamaran is semi-submerged.
  • the waterline is shown as 600.
  • the buoyancy of the hatches can raise the crane so it can be moved from anywhere on the vessel.
