Definitions

  • pipelines of both types can be wound onto a storage drum which is mounted on the deck of a pipe-laying vessel or barge, and which can then be unreeled from the drum in order to be laid on the seabed.
  • a line straightening device is preferably mounted on the deck of the vessel so as to co-operate with the drum, during reeling and unreeling, and in the latter case it acts to unbend the deformation necessarily applied to the line during initial winding onto the drum, and usually and desirably imparts a small degree of reverse bending, prior to descent to the seabed along a required catenary path.
  • a tensioning device may also be provided on the deck of the vessel, to co-operate with the straightening device, and which is used initially to draw the pipeline from the drum, although with requirement for progressively smaller tension force as the line commences its descent to the seabed, when gravity pull of the pipeline will assist the unreeling of the drum.
  • Braking mechanisms may be provided known per se to control the unreeling of the drum.
  • the buoyant drum may be arranged to receive upthrust directly from the sea in which the vessel is floating, in which case preferably it may be mounted in a "moonpool" in the hull of the vessel.
  • Figure 5 shows a practical embodiment of pipe laying vessel for carrying out the invention
  • Figure 11 is a side view corresponding to Figure 10.
  • Step 3 continue to load drum until all lengths are loaded, and all joints have been tested; insert pig and blow it through with compressed air until all water is expelled at end A; at end B remove pig and blank off; secure end to drum flange with a pipe clamp;
  • Step 5 continue to apply thrust and pull-up bullnose and set into keyhole using deck winch; remove bullnose and secure haul-in wire on drum flange;
  • Step 10 - pass the messenger cable down through the vessel moonpool, under the ship and across to the platform / buoy to connect the hose pull-in cable;
  • Figure 5 shows a 12 inch pipe being laid by being unwound from drum 203 after passing through pipe straightener / tensioner device shown schematically only by reference 205.
  • Device 205 acts on the unreeling pipeline in order to at least partly remove the deformation present in the pipeline as a consequence of having been wound on the drum 203, and may, according to requirements, apply a small amount of reverse bend to the pipeline, prior to downward discharge along a controlled catenary path in order to lay the pipe.
  • the pipe 206 which for illustration purposes is assumed to be a 12 inch diameter pipe, passes through the straightener device 205 and then down to the seabed, being guided along a 3 inch diameter guide cable, and the required catenary shape is maintained by application of suitable forward propeller thrust.
  • Another way of supplying a loaded drum to a vessel may involve arranging a reusable cartridge assembly, in which the drum is assembled with a supporting tank which can be filled with water to support the weight of the drum, and the entire cartridge can be mounted in the pipe laying vessel to unreel pipe for a pipe laying operation, and when the drum is completely unreeled, the cartridge can be removed and replaced by a fresh one.
  • Figures 10 to 12 generally correspond with the schematic illustration of Figure 6, and shown in more detail the path of travel along which an unreeling pipeline is constrained to follow in practice. Parts corresponding with those already described and illustrated in Figure 6 are given the same reference numerals.

Abstract

L'invention se rapporte à un procédé et à un appareil de pose/récupération de conduits flexibles (206) au fond de la mer à l'aide d'un navire (201) de pose de conduits possédant un cylindre flottant (203) de façon à ce qu'il soit soutenu par un corps de liquide, par ex., l'eau de mer, dans un bassin (202) du navire dans lequel il est partiellement immergé. Le cylindre est supporté par des surfaces d'appui du navire afin de tourner autour d'un axe horizontal, et la charge appliquée sur les surfaces est réduite grâce au pouvoir flottant du cylindre ce qui facilite également l'enroulement et le déroulement des conduits flexibles qui ont lieu dans le bassin de manière à ce que le système puisse fonctionner facilement à différentes profondeurs d'eau, et puisse déposer les conduites flexibles en eau profonde.
