Definitions

  • the present invention relates to a floating terminal on which a shuttle tanker lays down and performs cargo handling, and more particularly to a mooring method and apparatus thereof.
  • Patent Document 1 US Pat. No. 6,546,739
  • An object of the present invention is to reduce a relative vertical displacement generated between a floating terminal and a tanker beside the floating terminal in bad weather.
  • a pedestal that protrudes outward from the submerged portion of the side of the floating terminal is provided, and the bottom of the tanker that is laid on the terminal is placed on the cradle Put it on. By doing so, it is possible to prevent relative displacement such that the tanker descends against the terminal when swells are received.
  • FIG. 1 is a cross-sectional view of a floating terminal during cargo handling.
  • FIG. 2 is also a plan view.
  • FIG. 3 is a cross-sectional view of a terminal when a tanker is joined.
  • FIG. 4 is a cross-sectional view when swell is received during cargo handling.
  • Fig. 1 is a sectional view during LNG unloading operation
  • Fig. 2 is a plan view.
  • Reference numeral 10 denotes a floating terminal as a floating LNG offshore receiving device, to which an LNG tanker (shuttle tanker) 30 is moored sideways.
  • the illustrated floating terminal is a modified repair dock that allows adjustment of draft and trim heel.
  • This terminal is equipped with a turret 12 (one-point mooring device) at the front, and the turret is a chain
  • a fluid swivel is incorporated in the turret 12, and a riser pipe 13 extending from the submarine pipeline is connected to the turret 12.
  • the floating terminal 10 includes a power generator, a ballast pump, a mooring winch, and the like.
  • the floating terminal 10 immediately gasifies the liquefied gas received from the shuttle tanker 30 with the gasifier 14, and then converts it from the turret 12 to the land via the submarine pipeline. Send to gas facility.
  • a receiving base 15 is provided.
  • the cradle may be provided only on one side if it is determined in the figure that the side of the power tanker provided on both sides is fixed. Alternatively, the cradle 15 may be provided over the entire length of the floating terminal, or may be only a part if the tanker to be mounted is small.
  • the cradle 15 is a cantilever structure, and a large bending moment acts on the base of the cradle 15. Therefore, the cradle 15 has a box structure with a sufficiently large depth with respect to the width. Touch with S.
  • a fender 16 (for example, rubber or wooden) is attached to the upper surface of the cradle so that the bottom of the tanker is not damaged.
  • Reference numeral 17 is a fender fender.
  • seawater ballast is loaded on the floating terminal 10 to deepen the draft so that the cradle 15 does not collide with the tanker.
  • the mooring line is drawn up, the tanker is placed sideways, the floating terminal ballast is discharged to make the draft shallower, the tanker 30 is placed on the cradle 15, and a part of the weight of the tanker is placed on the cradle.
  • Use force Figure 1).
  • mooring lines 18 are passed between the terminal and the tanker and tightened (Fig. 2).
  • Ordinary mooring lines are effective to stop the relative movement of the ships in the horizontal plane, and are almost powerless to stop the relative movement in the up and down direction. Therefore, as shown in Fig. 1, several mooring lines 18a among these mooring lines are stretched so as to extend vertically from the tanker to reach the mooring bit 20 on the terminal.
  • a mooring bit 20 may be provided on the side of the terminal 10 so that the mooring line can be stretched downward in this manner even from a small tan force.
  • the cargo lines of the two ships are connected to each other by the loading hose 19, and the unloading work is performed.
  • the tanker 30 being unloaded has its draft gradually shallower by the amount of unloading, so the floating terminal drains the ballast and gradually reduces the draft, and the bottom of the tank with a tank force of 30 is placed on the cradle 15. Keep it always on.

Abstract

La présente invention concerne un terminal flottant (10) doté de bases de support (15) projetant vers l'extérieur depuis ses parties latérales submergées. Le fonds d'une citerne (30) amenée le long du terminal est placée sur une base de support pour éviter à la citerne d'être déplacée vers le bas par rapport au terminal quand la citerne reçoit des houles. Une ligne d'amarrage (18a) est étirée de manière à s'étendre de la citerne vers le terminal pour éviter à la citerne de se déplacer vers le haut par rapport au terminal.
