Definitions

  • ABSTRACT The movement of a section of a ship during assembly or repair is facilitated by cushions of pressurised fluid positioned beneath the section, lateral escape of the [30] Foreign Application Priority Data Sept. 23, I97] Great Britain.................... 44397/71 'l t Cl I 214/1 BE fluid being prevented by flexible skirts. When in position the section is raised to a desired height by fluid inflatable lift bags. The fluid may be water, and when [58] Field of Search................... 214/1 BE, I2, 152; 114/435, 45, 46, 77 R; 180/127, 128, 129,
  • This invention concerns a method for moving into position sections of ships during their assembly or repair.
  • the invention consists in a method of moving a section of a ship into position wherein the section is supported on at least one cushion of pressurized fluid positioned beneath the section, lateral escape of the fluid from the cushion being substantially prevented by a skirt of flexible material.
  • the propulsive effort to move the section may be provided by winch and cable means, and when the section has been moved into the correct position relative to the remainder of the ship it may be raised to the required height, if desired, by means of fluid inflatable lift bags.
  • Each lift bag may be an integral part of a flexible skirt, the two forming a fluid inflated movement and lift pad.
  • the lift bags may be separate, being placed in position in the deflated condition, so that the ship section is moved into position over them and they are then inflated to lift it into position(
  • the pressurized fluid for the cushion and for inflating the lift bags may be water or air, sea water being a very convenient source of fluid in ship repair dry docks.
  • FIG. 1 is a perspective view of part of a large oil tanker in dry dock
  • FIG. 2 is an enlargement of a part of FIG. 1 illustrating skirt pads
  • lateral stability of the repair unit 12 during its elevation into position in the bottom of the tankerIO may be obtained by external means such as guide wires suitably deployed to strong points in the base of the dock.
  • stability may be built 7 into the lift bags.
  • FIG. 3 is an enlargement of a part of FIG. 1 illustrating lift bags.
  • a 250,000 t.d.w. oil tanker 10 having a damaged skin on part of its hull bottom is positioned in a dry dock 11 so as to be to one side thereof.
  • the damaged skin is cut away and removed.
  • a repair unit 12 is assembled on the floor of the dry dock 11 clear of the underside of the tanker 10.
  • the repair unit 12, which weighs in the order of 1,000 tons, is supported on six rails 13 which run across the floor of the dry dock l l to a position beneath the hole in the underside of the tanker 10 into which the repair unit 12 has to be fitted.
  • the clearance between the underside of the tanker l0 and the floor of the dry dock 11 is in the order of six feet, whilst the total thickness of the repair unit 12 is in the order of five feet six inches.
  • skirt pads 14 (illustrated diagrammatically in the drawings) of flexible material are positioned beneath the repair unit 12, a pair of skirt pads 14 being positioned between each alternate pair of rails 13.
  • the sides of the skirt pads 14 are restrained by suitable means such as strips of metal (not shown) releasably attached to the underside of the repair unit 12.
  • Each skirt pad 14, which measures in the order of feet by 15 feet, is supplied with pressurized fluid at a pressure of five pounds per square inch by way of flexible supply pipes 15.
  • the pressurized fluid may be air, but in a dry dock where a good head of sea 6 water is available, this sea water is a very convenient source of fluid.
  • Each flexible skirt pad 14 is preferably constructed to include a sheet of flexible material which lies adjacent the underside of the repair unit, the skirt part,
  • the skirt part which is constructed of flexible sheet material, depending downwardly from this sheet.
  • the skirt part may be of corrugated form in verticalcross-section, the concavities of the corrugations facing towards the cushion. Where the space between the underside of the repair unit and the floor of the dock is limited, the skirt part may be a single convolution, again being concave towards the cushion. The free edges of the skirt part are held in position against the pressure of the cushion by ties or webs attached back to the sheet of flexible material which lies adjacent the underside of the repair unit.
  • the pressurized fluid supply pipes 15 may be brought into each skirt pad through the skirt part; however, if the height of the skirt pad is too small to allow this the pipes may be brought into the top of the skirt pad through feed holes in the repair unit, these holes being made good when the repair unit is in position.
  • a method of moving a section of a ship into position for assembly and/or repair of a ship in a dry dock comprising the steps of:
