Definitions

  • bridge sections When laying pipelines on the seabed, such pipe sections are referred to as bridge sections which, due to differences in height of the floor, run above it and form span sections which connect two successive points of natural support of the pipe with one another.
  • the prior art provides for the filling of valleys a sea floor in the area of the section in which the pipelines are to be laid. For this purpose, not insignificant masses of soil, stones, gravel or the like are used to form a flat support area.
  • the invention is therefore based on the object of specifying a structure for supporting underwater pipelines with exposed spans, which enables automatic laying and direction, can be implemented as simply as possible, a universal, multiple use and settings and readjustments during and after Lifting the line permitted.
  • Another task is to provide a Vorrich device for the system, its actuators are simple and do not lose their functionality in the underwater area after a long period of use.
  • the devices for actuating the individual organs de underwater device should be designed so that they can be controlled from the surface with known remote control organs.
  • the device according to the invention should allow maintenance, adjustment and repair work without difficulties at any time after installation. If necessary, the replacement and removal of parts or the entire device should be possible without difficulty. Last but not least, the device should be simple, efficient and safe to operate and economical to manufacture and operate.
  • the invention provides a system for storing and supporting bridge sections for underwater water pipelines, each of which has a frame which carries a vertically movable slide with self-locking which has mechanically spreadable pliers grippers in its lower region which can be gripped and lifting the pipeline can be locked; the frame also has extendable self-locking supports and coupling means with a laying module from which all the functions of the device can be controlled.

  • Figure 4 is an enlarged section of a vertical section through a
  • the support device for underwater pipelines essentially consists of a rectangular, metallic tubular frame 1 with four corner columns 2, which are connected to one another by four upper horizontal beams 3 (see FIG. 3).
  • the corner pillars 2 are only connected to one another by lower horizontal beams 4 on two opposite sides (see FIG. 2), while, according to FIG. 1, angled connecting beams 5 are provided on the other two sides, which produce the necessary rigidity, from the upper horizontal beams 3 go out and are attached with their lower ends to a corner column 2.
  • the two sides where the corner columns 2 are also connected to the lower horizontal beams 4 are referred ⁇ referred to as longitudinal sides of the frame 1 where the components thus extend in the longitudinal direction, while the other two sides on the front side of the frame 1 are designated where the individual organs extend in the transverse direction.
  • the upper horizontal beams 3 and the lower horizontal beams 4 are connected to one another by two parallel, vertical guide rods 6 (FIG. 2), on which a slide 8 is mounted so as to be displaceable via sleeves 7.
  • a slide 8 is mounted so as to be displaceable via sleeves 7.
  • the upper sections of the guide rods 8 are composed of truncated cone segments 9, which are coaxially one above the other and are arranged upside down so that that the larger base pages face up.
  • the truncated cone segments 9 cooperate with radial, in one plane holding projections 10 (see FIG. 4), which are formed on the inner circumference of the sleeves 7 and project in the direction of their central axis and thereby form projections of vertical, elastic lamellae 11, which in the lower region are connected to one another in a circle, whereby a deformable cylinder 12 is formed (cf. also FIG. 2).
  • a one-way blocking system is formed, which can be referred to as a "spring fingers" (press finger system).
  • the carriage 8 connected to the sleeves 7 consists of a lower rectangular frame 16 and an upper, somewhat smaller rectangular frame 17, both of which are connected to one another by four oblique struts 18 (cf. also FIG. 3).
  • the longitudinal side of the lower rectangular frame 16 are connected to the plates 17 arranged above it by tie rods 19, which form a threaded spindle system with a nut and are actuated by vertical rods 20 which run through the upper horizontal support 3 of the frame 1 and for reasons explained in more detail below protrude.
  • each column 2 At the upper end of each corner column 2, connector elements 34 are provided.
  • each column 2 In each column 2 are displaceable supports 35 which are fully retracted into the columns 2 in the position of FIG. The supports 35 can emerge from the columns 2 on the basis of their own weight.
  • the support 35 has holding mechanisms by means of which it can be locked in the fully retracted position of the columns 2 and essentially in any extended position in the manner explained below.
  • the supports 35 have an axial pin 36 which engages in the associated connector element 34 and is held there by a cylinder 38 via its head 37.
  • the cylinder 38 is designed to be broken down and expandable to release the head 37 when pressure is exerted by a conical plug 39 which seals the connector 34 upward.
  • FIG. 5 also shows that the supports 35 in the lower part consist of a series of truncated cone segments 40, which are arranged upside down coaxially one above the other so that their larger base area points upwards.
  • the truncated cone segments 4 have the task of interacting with radial retaining projections 41 lying in one plane, which are attached in the lower part of the corner pillars 2 and extend in the direction of the respective longitudinal central axis, thereby forming vertically extending, elastic slats 42 arranged in the circumferential direction , which are circularly connected to each other in the lower area.
  • a unidirectional locking system is formed, which can be referred to as a "spring fingers" (press finger system), which has the same function as the above.
  • each support 35 is connected via a hinge 43 to a foot 44, which consists of a large, rectangular base plate 45, on the underside of which Rip pen 46 intersecting at right angles are formed.
  • the connector elements 34 at the upper end of the corner pillars are used for connection to an installation module (not shown) for the support device with its frame 1.
  • the installation module has the following equipment: Means for gripping and pulling up the coupling plate 33 de slide 8,
  • ROV Remote Operative Vehicle
  • the mutual interaction of the holding projections 10 and the truncated cone elements 9 allows a free displacement of the slide 8 upwards, but prevents it from sinking, so that the frame 1 can be uncoupled from the laying module after completion of the laying units, in order to subsequently take over the supporting function alone z .
  • the support device can have an anodic protection system that extends its service life and, because of the electrical insulation from the pipeline with the aid of the polyethylene coatings of the pliers grippers, does not impair the electrolytic protection system.
