Definitions

  • the invention relates to a fluid transfer system
  • fluid conducting flexible pipe having a first and seco connector end, which pipe during use extends over an area water, preferably totally or partially submerged in t water, between a first and second hook-up point and, when n in use, is stored near the first hook-up point, a ramp curv downward in the vertical plane for supporting the flexib pipe during the transfer thereof from storage position position for use, and vice versa, and a means, e.g., lifting cable, for feeding out/hauling in the flexible pi via said curved ramp, the lower detached end of which situated at a distance from the adjacent first hook- point.
  • a means e.g., lifting cable
  • the invention was developed primarily in connection with t need for a fluid transfer system between a maritime floati oil storage facility, for example a large barge with o storing capacity, and a so-called shuttle tanker.
  • the o tank barge is anchored or dynamically positioned at the o production field and serves as an intermediate storage mea for the oil produced. From this barge the oil is load over into tankers, which on arrival at the field a connected to the barge by suitable mooring means, whereaft a fluid conducting pipe connection is established between t barge and tanker.
  • the fluid conducting pipe connection formed by a fluid conducting pipe which, when not in use, stored on the barge.
  • the flexible pipe from the barge is fed down in the water via a ramp curved downward in the vertical plan which supports the flexible pipe in the initial phase connection.
  • the other end of the pipe is hauled on board t tanker and there is hooked up to a manifold, or the lik
  • the flexible pipe end at the barge is also connected to suitable hook-up point on the barge, whereafter the flui transfer may begin.
  • the flexibl pipe is suspended between the barge and the tanker, more less submerged in water, or if desired is freely suspende above the water surface.
  • the flexible pipe i disconnected on the tanker side and dropped down into th water, whereafter it is disconnected on the barge side an then hauled in via the aforementioned curved ramp, to b stored on the barge until it is to be used again " .
  • the hook-up on the barge side can lead to difficulties due t the fact that feeding out the relatively long flexible flui conducting pipe requires a ramp which must have a certai degree of minimum curve, in order thereby to avoid damagin bend stresses on the pipe. This means that the ramp mus extend some distance out from the barge, usually from one o its ends.
  • the hook-up point on the barge i preferentially situated very close to, almost in, the actua end of the barge, which means that there is a considerabl distance between the pipe's barge connector end and the hook up point on the barge — a distance rendering it mor difficult to connect the pipe connector end to the hook-u point on the barge.
  • An object of the invention is t provide a fluid transfer system where, in particular, thi connection problem is solved in a simple and reliable manner and according to the invention it is therefore proposed tha in a fluid transfer system of the type described above, th ramp shall be ovably mounted for movement from a positio for feeding out/hauling in the pipe to a position closer an so oriented relative to the adjacent hook-up point that sai first connector end may be brought into at least approximate ly aligned coupling position vis a vis the adjacent firs hook-up point .
  • the ra i s used as a means for moving the flexible pipe so that may relatively easi ly be connected to the adj acent hook- point .
  • the ramp may be moved horizontally or vertically or intermediate diagonal directions, all depending on t positioning and orientation of the ramp end and the hook- point relative to one another.
  • the ramp is designed so as extend outward over the hook-up point, and it is th pivotably mounted in the vertical plane. It is particular advantageous for the pivotal movement to utilize a parallel gram joint mechanism.

  • Cable 13 leads to a winch, not shown, which in Fi 4 may be activated to draw up connector end 9 for connecti to hook-up point 8.
  • a steeri device 14 is provided at the bottom of ramp 11, at the free end thereof. This serves to steer and maneuver t pipe end so that when being fed out the pipe is controllab moved in when pipe end 9 has passed the lower main roller 1 until lifting cable 13 in the end piece comes into conta with the lower main roller 16 or the ramp support surface or, conversely, so that the pipe end is steered in onto ra 11 when the pipe is to be hauled in.

  • the invention is shown and described above in connection wit a preferred embodiment, where the ramp extends in the sam vertical plane as that in which the hook-up point lies.
  • Th inventive idea resides in the fact that the ramp is used as maneuvering element to bring the connector end of the pip into a position that is close enough and so oriented relativ to the hook-up point that connection can take place preferably with the aid of a cable used during feeding out hauling in of the pipe; therefore, it is also within th scope of the invention to conceive of an embodiment where th hook-up point is situated to the side of the ramp, with th ramp then being designed for pivotal movement horizontally in order thus to manipulate the pipe into correct hook-u position.
  • For the pivotal movement of the ramp differen pivot mechanisms from the one shown and described may b used. Such pivot arrangements will be well known to a perso skilled in the art.

Abstract

L'invention se rapporte à un système de transfert de fluides, comprenant: un tuyau flexible conducteur de fluide (4) ayant des première (9) et seconde extrémités de raccord, tuyau qui, pendant l'utilisation, s'étend sur un plan d'eau, de préférence totalement ou partiellement immergé dans l'eau, entre des premier (8) et second (7) crochets de suspension et qui, pendant sa non utilisation est stocké (5) à proximité du premier crochet de suspension (8); une rampe (11) incurvée vers le bas dans le plan vertical et servant à soutenir le tuyau flexible (4) pendant son transfert de la position de stockage à la position d'utilisation et vice versa; ainsi qu'un organe (13) servant à dérouler/enrouler le tuyau flexible (4) via la rampe incurvée (11), dont l'extrémité inférieure est située à une certaine distance du premier crochet de suspension adjacent (8). La rampe (11) est montée mobile (12) pour pouvoir se déplacer d'une position de déroulement/enroulement du tuyau à une position plus proche et elle est orientée par rapport au point de connexion adjacent (8) pour que la première extrémité de raccord (9) puisse être amenée en position de couplage au moins approximativement alignée en face du premier crochet de suspension adjacent (8).
