Definitions

  • the invention relates to a method and devices provided therefor for mooring a ship to a building. It relates in particular to the mechanical mooring of a tanker at a station standing or floating in the sea for the transfer of oil, liquid gas or similar substances.
  • the invention has for its object to greatly simplify the process of mooring a ship to a sea structure, even under difficult conditions, and to significantly shorten the timing of the mooring, without the need for manual operations and without support from tugs or other auxiliary ships. Furthermore, the high accident risk inherent in the known measures is to be eliminated by the invention.
  • a fixed line of limited finite length is used, which is attached at both ends to the structure, and this fixed line is formed into a large loop above the height of a bollard and as soon as the bollard is in the area below the loop , lowered to the height of the bollard and partially placed around the bollard. Thereafter, a force aimed at increasing the distance between the two fastening points of the fixed line and the bollard wrapped by it is used to tension the fixed line and is maintained to maintain the tension during the mooring period.
  • the size of the loop is chosen so that the bollard can still be brought under the area of the loop even in rough seas and large ship movements.
  • the bollard is expediently located in an exposed position on the bow of the ship and the fixed line is held ready on the outrigger of a lake structure. In the case of smaller sea structures or floating buoys, however, it may be useful to attach a boom to the ship, for example on the bow, and a bollard or a similar fastener on the structure.
  • the fixed line is spread out to form an approximately trapezoidal loop and is held ready at a variable height on the structure, when a ship is approached for mooring in each case to the height dependent on the sea state and ship height up to just above the bollard brought under tension and only then further lowered and loosened over the bollard, so that the fixed line partially wraps around the bollard and its two halves can be stretched in length by increasing the distance between their two attachment points and the bollard.
  • a device for carrying out the method according to the invention has an outrigger when the ship approaches the building, for example via a bollard or a similar fastening device, under which the fixed line to be fastened to the bollard is arranged (as known from FR-A 2 368 399) and is characterized by the fact that the boom is widened according to the shape of the loop of the fixed line to be kept ready, on the extension on both sides of the deflection pulleys are arranged and over the deflection holding or spreading lines are guided, at the lower ends of which the fixed line in blocks by means of blocks Is held in the form of a loop, the fixed line having a finite length and preferably being fastened at two fastening points to a column supporting the boom.
  • the boom is a fork-like spreading boom, on the spreading arms of which deflection rollers for the spreading lines are arranged, the boom being pivotable about a horizontal axis.
  • the boom is preferably pivotable by means of a hanger rope.
  • the arms of the boom are advantageously bent downwards.
  • the spreader lines run over a constant tension device or a similar length compensation device, so that they can adapt in an approximately tensioned state to the height movements of the fixed line attached to a bollard as a result of swell or the like.
  • the ejector is arranged on a sea structure, in particular on the rotatable column of a loading tower for oil or liquid gas, and the fixed line is movably attached to a slewing ring of the same column, while the bollard is attached to a ship, preferably approximately on its bow, located and is arranged on a stage movable in the longitudinal direction of the ship beyond the bow.
  • the boom is expediently located on a structure, such as on the column or the rotatable upper part of a loading tower for oil or liquid gas, and the fixed line is movably attached to this column.
  • the bollard is located on a ship berthing the loading tower, preferably on a stage that can be moved beyond the bow. The stage is advanced during mooring and pulled back into the ship during loading so that it is not exposed to waves.
  • the approach of the ship to the loading tower can be determined and controlled by electronic devices, whereby the occurring distances and ship movements can be continuously checked and compensated. It is also possible to remotely control the lowering of the boom and the release of the spreading lines from the ship.
  • the mooring process can thus be carried out mechanically and without any manual work, even in unfavorable sea conditions and weather conditions.
  • the bollard is designed in the form of a standing drum with an increasing diameter and is rotatably arranged about a vertical axis on a bollard chair which is mounted in the stage so as to be pivotable about a horizontal axis.
  • a z. B known on a buoy to be fastened device with a bollard that can pivot after releasing a lock under the pull of a fixed line around it around a horizontal axis and thereby release the fixed line.
  • the bollard according to an embodiment of the invention is arranged in a swivel bollard in a stage of a ship.
  • a clamping device is additionally arranged, which can clamp the fixed line on the lower part of the bollard.
  • the bollard chair is folded forward, for example, by 85 °, so that the line can slide over the bollard or be lifted off it while the ship is moving away from the loading mast.
  • the fixed line hangs freely as an approximately semicircular loop on a system of holding lines with blocks and compensating rollers on the extension of a column and can be lowered or raised, the holding lines being guided to a winch via deflection rollers , which has drums of different diameters and / or different speeds, which are matched to the changes in length of the various tether when lifting or lowering the fixed line.
  • the bollard can also be arranged on the ship on a foldable stage that is movable about a horizontal axis on the bow. In this case, the stage remains in a horizontal position for the duration of the mooring and is only folded back after the mooring line has been released.
  • This arrangement of the bollard as well as the suspension of the fixed line directly on the boom, which carries the transfer devices for the cargo, can be used if extraordinary, bad weather conditions are not to be expected.
  • the fixed line is at its attachment points via damping devices, for. B. elastic on damping springs and preferably movably attached on all sides so that they follow the movements of the ship caused by swell and can compensate for temporary changes in distance.
  • the column 1 of a loading mast which may be movably anchored in the sea, has a loading arm boom 20 on its rotatable head part 14.
  • the fixed line 5 is by a boom, in the example shown in FIGS. 1 and 2 by a spreader tree 2, by means of deflecting rollers 9, which are arranged on the loading arm 20, and deflecting rollers 11, which are located on the arms 10, spreading lines 7 and spreading blocks 8 held ready and spread to a loop, the width of z. B. corresponds to the average width of the ships to be moored.
  • the spreading lines 7 can be pulled or released by the winch 12.
  • the spreader tree 2 is pivoted about a horizontal axis 23 via a hanger rope 21 and a winch 22.
  • Its rest position 2a is indicated by dashed lines.
  • the spreader boom 2 is lowered into the fully excellent position.
  • the ship 13 is provided with a stage 15 which can be advanced over the bow and on which the bollard 16 is arranged in a swiveling bollard chair 25. With the stage advanced to position 15a, the bollard 16a is in front of the bow of the ship.
  • the fixed line 5 is lowered over the advanced bollard 16a and tensioned by pulling back the bollard 16 and moving the ship back into position 5a.
  • the sliding stage is shown in Figure 3 posed.
  • the hook-shaped bollard 16, which is rotatable about a vertical axis, has the shape of a standing drum with an increasing diameter. He sits on the bollard 25, which can be pivoted about a horizontal axis of rotation 26 in the stage 15 by means of a hydraulic device 27. It is held in the position shown by a hydraulically moved holding block 28.
  • a pair of clamping brackets 17 is provided on both sides of the bollard 16 and can be pivoted by means of a hydraulic system 18 from a retracted rest position into a vertical operating position, in which the fixed line 5 is clamped to the bollard 16 at the bottom.
  • the stage 15 is displaced via a lever device 19 or in another suitable manner.
  • the loading arm 120 is widened by cross members 110, at the ends of which the guide lines 107 run over deflection rollers 109 and 111 from a winch 112 to blocks 106 on the fixed line 5.
  • the tether lines 107 are partially connected by compensating rollers 108.
  • the fixed line 5, which is initially formed into an approximately semicircular loop at least in its central part, can be lowered into the position 5b shown in FIG. 5, where it wraps around the bollard 16 of the ship 13 shown here and as in FIG. 4 shown, is stretched into position 5b.
  • the mooring line can also be lowered to position 5c if smaller ships are to be moored.
  • a foldable platform 115 is used, which in the rest position can be pivoted upwards about a horizontal axis 114 by means of a hydraulic system 119.
  • the length and width of the trapezoidal or arched loop of the fixed line 5 are many times the largest diameter of the bollard 16. Since the bollard 16 is preferably rotatable, it can be gripped by the fixed line 5 at any point along the circumference of the fixed line and move along it until the line 5 is tensioned. The rotatability of the bollard, which is wrapped only about half of its circumference, also shows that even when the moored ship swoops, the two halves of the fixed line 5 stretched in stretched length are evenly loaded at least when the clamps 17 are loosened.
  • the devices according to the invention can be modified in various ways.
  • the jib holding the fixed line can, for example, also be arranged laterally on the ship in order to lay the line over a bollard or a similar device of a structure in the harbor or a pontoon or another ship. It can be useful to be able to pull the fixed line using a winch.
  • the mooring is done in these cases without dangerous manual work, can be controlled mechanically from the bridge or another control center, is at least partially automated and is faster than the usual mooring.
  • B. first auxiliary lines are caught or fished, with which the line rope is then tightened.
