    Method for placing a mooring buoy anchoring, wherein a tubular pile, without swivel, is driven into the water bottom to the desired end depth so that the upper end of the tubular pile is above the water bottom and below the water surface and then a swivel is lowered into the water and is mounted via a bearing at the top end of the tubular pile. When repaired, the tubular pile remains in the water bottom, the swivel is dismantled and lifted out of the water. The inventive mooring buoy with swivel comprises a tubular pole and a swivel mounted therein or mounted thereon.

    Mooring buoy with easily exchangeable swivel; and method for placing or repairing a mooring buoy anchor.
    The mooring buoy anchors comprises a steel tubular pole which is equipped at its upper end with an anchor point mounted around a horizontal or substantially perpendicular to the longitudinal axis of the tubular pole, the so-called swivel. The tubular pile is placed vertically in the water bottom, at least 10 meters deep, so that only the upper part, about 1 or 2 meters long, for example between about 0.5 and 1 meter, protrudes from the water bottom at a water depth of for example at least 10 meters . A mooring buoy floating on the water is anchored to the swivel via an anchor chain. A seaworthy ship, such as a container ship, can moor at the mooring buoy. The mooring buoy must be able to withstand a pulling force of at least 100 tonnes.
    It is customary to remove the entire tubular pile from the water to carry out maintenance on the swivel. This is cumbersome and time-consuming. Furthermore, when replacing the tubular pile at the same location, the original loadability cannot be guaranteed because the bottom has been stirred by removing the tubular pile.
    The invention aims at avoiding the foregoing and / or other disadvantages.
    To this end, it is proposed to make the swivel easily interchangeable so that the tubular pile no longer has to be removed from the water bottom for maintenance of the swivel. It is also proposed to place the tubular pile in the water bottom without the swivel, for example by vibrating or driving, and then, preferably after the tubular pile has been brought to its final depth, to mount the swivel.
    To this end, the swivel is preferably pivotally mounted in a bearing located on the tubular pile, a portion of which is removable, preferably by loosening a screw or bolt connection or removing a (rivet) nail connection, so that after dismantling thereof the swivel can be lifted out of its bearing. The bearing is preferably dismountable in such a way that after dismantling the swivel is removed with a movement perpendicular to the longitudinal axis of the tubular pile and / or perpendicular to the pivot axis of the swivel.
    According to the invention, whether or not in combination with one or more aspects of the foregoing or the following, the swivel is equipped with two mutually aligned shaft stubs, preferably solid, which provide the swivel axis of the swivel and which project into a bearing, preferably plain bearing. , functioning holes on the tubular pole. The use of this type of bearing (an axle stub rotating in a close-fitting hole) is different from the prior art in which the swivel comprises a circular shaft sleeve which is inserted onto a close-fitting hinge pin which is welded to the tubular post after the shaft sleeve is welded onto the hinge pin has been stung.
    In a favorable embodiment, the bearing comprises at least one, preferably at least two releasable locking blocks which block a removal channel serving for the passage during disassembly of an axle stub of the swivel. At least one of the retaining blocks preferably provides a portion of the hole wall of the bearing hole in which the shaft stub is received. At least one of the retaining blocks has a tapered shape, preferably widening in the direction of the upper edge of the tubular pile, to facilitate removal of the retaining block.
    A circular arc segment is preferably part of a demountable component of the hole wall of the bearing hole such that the swivel's shaft stub can move in and out of the bearing hole when the arc is removed, moving in the radial direction of the bearing hole.
    The bearing preferably comprises at least two mutually substantially parallel metal plate elements that support a bearing shell between them and at least one of which is preferably pierced by an axle stub associated with the bearing shell and the plate elements. One or both plate elements preferably contain the take-out channel.
    The plate elements are preferably permanently fixed to the tubular pile. The bearing is preferably associated with two diametrically opposite locations on the tubular pile.
    The take-out channel preferably opens at the top of the tubular pile and / or comprises two mutually enclosing longitudinal parts.
    The swivel is preferably of cast steel, for example of S355 quality, and / or comprises two mutually aligned stubs.
    In the drawing showing a non-limiting example, the given dimensions are in millimeters. In the drawing:
    FIG. 1: View in perspective of the upper part of the tubular pile, including the removable swivel, mounted.
    FIG. 2: top view of fig. 1.
    FIG. 3: section A-A of FIG. 2.
    FIG. 4: front view of the swivel.
    FIG. 5: side view of the swivel.
    FIG. 6: the locking blocks in front, side and top view.
    FIG. 2 shows the plate elements forming a gap between them, in which the tongue or spring of the retaining blocks is closely received.
    The retaining blocks 1, 2 (see Fig. 3) both have a taper or wedge shape, opposite to each other. The stub axle 3 is partly supported by the block 1.
    FIG. 4 shows the axle stubs 3 that are inserted into a bearing hole.
    The retaining blocks (see fig. 6) are equipped with a type of brass or spring that fits into the gap between the plate elements. The size "B" is variable.
    Many embodiments belong to the invention. A measure constitutes, individually or in combination with one or more other measures as disclosed herein, the invention. Thus, it is intended that herein be a basis for each measure individually, separately from the combination in which it is disclosed here, to independently or randomly in combination with one or more other measures disclosed herein, form the basis for a patent claim.
