Description

  The present invention relates to a mooring device for a floating structure such as a pier or a platform. More particularly, the present invention relates to a mooring device that can fix a floating structure using an embeddable mooring pile and a surrounding mooring dolphin. This device makes it possible to attach the floating structure to a mooring pile having a lower fixed part that is pushed into the seabed and an upper detachable part that is bolted to the lower fixed part with flanges.

  The mooring pile formed in this way is attached to the floating structure using adjustable mooring dolphin that takes into account the allowable construction eccentricity of the position of the mooring pile compared to the design position.

Floating structures affected by wind, waves, and flow are moored to prevent leaving the designated location. Conventional mooring devices
(A) a mooring line tied to a shore-side pole with a fender to prevent the floating structure from colliding with the land side;
(B) Utilize a single continuous length mooring pile pushed into the seabed and a mooring dolphin connecting the floating structure to the mooring pile.

  One patented design uses elastic ropes to connect the bottom of the floating structure to a fixed point located on the sea floor.

  The disadvantages of the existing methods are as follows.

  (A) A mooring line tied to the shore enables the floating structure to move in the direction of the bow and stern. In addition, the mooring line does not prevent the floating structure from rolling and rolling.

  (B) The mooring pile solves the above problem, but the conventional single continuous length mooring pile requires clearing the area of the floating structure for other use, It cannot be removed periodically from the position of the mooring pile.

  The disadvantages associated with the patented mooring device that uses elastic cords attached to the seabed at the bottom of the floating structure allow this mooring device to move horizontally in a restricted range, Allowing the floating structure to rotate and move vertically.

  The present invention eliminates the drawbacks associated with the prior art, attaches a floating structure to a mooring pile, and further anchors the portion of the mooring pile that protrudes above the seabed to prevent disturbance to nearby boats or other activities. A mooring device is provided that allows the to be removed. This device allows movement of the floating structure in the vertical direction, similar to a conventional mooring pile, but has the advantage of opening up space for other uses by removing the protruding portion of the mooring pile.

More particularly, the present invention provides:
(A) a mooring pile consisting of two parts including a lower fixing part pushed into the seabed and an upper attaching / detaching part;
(B) A flange bolting mechanism between the lower fixed portion and the upper detachable portion of the pile to form a complete mooring pile,
(C) An adjustable mooring dolphin that is adaptable to eccentricity at the location of the mooring pile due to construction tolerances.

  Further objects of the present invention will become apparent from the following disclosure and description of the invention.

It is a front view of the flange which connects the downward fixing part and upper attachment / detachment part of a mooring pile. It is a top view of the flange which connects the downward fixing part and upper attachment / detachment part of a mooring pile. It is a front view of the front-end | tip part of the upper attachment / detachment part of a mooring pile. It is a top view of the upper attachment-and-detachment part of a mooring pile. FIG. 6 is a plan view of an adjustable mooring dolphin. FIG. 6 is a front view of an adjustable mooring dolphin that is perpendicular to the floating structure. FIG. 5 is a front view of an adjustable mooring dolphin that is parallel to the floating structure.

  For the convenience of understanding the present invention, a preferred embodiment will now be described by way of example with reference to the accompanying drawings.

  The main requirement for mooring units is to keep floating structures such as dredges, platforms, piers, etc. safely under natural conditions while keeping the movement of the floating structures within safety limits that meet the requirements of the floating structure application. It is to restrain. Normally, fender-type mooring dolphin is used to protect the floating structure from fixed mooring piles. According to the design of the present invention, the bracket is fitted and welded to the upper end and the side surface of the floating structure. One or more studs are clamped to the bracket to engage the interior of an elongated groove formed in the mooring dolphin securing arm. The groove acts against the reaction force and allows a regulated and adjustable movement of the mooring dolphin relative to the floating structure so as to adjust the back and forth movement of the floating structure.

  The mooring pile is installed around the floating structure at a predetermined location in the field, and the floating structure is attached to the mooring pile by adjustable dolphin.

  To remove the upper detachment of the mooring pile, the mooring dolphin is removed from the floating structure and the adjustable mooring dolphin section is completely removed. The fastening bolt that connects the upper attaching / detaching portion of the mooring pile to the lower fixing portion of the mooring pile is removed, the upper attaching / detaching portion is shifted, lifted, and taken out from the water.

  Referring to the drawings in more detail, FIG. 1 shows a flange joint between a lower fixed portion and an upper detachable portion of a mooring pile body. Moreover, the figure has shown the downward fixing part of the mooring pile pushed into the seabed.

  FIG. 2 shows the details of the flange joint between the lower fixed part and the upper detachable part of the mooring pile, including pile dimensions and flange thickness. A plan view of the flange is shown in FIG. 3 representing the positioning of the connecting bolt. When the lower fixed part of the mooring pile is pushed into the seabed, the upper attaching / detaching part of the mooring pile needs to align the bolt holes in order to connect the two flanges by bolting. The lower pile may be filled with sand, gravel, etc. to increase its stability.

  4 shows a front view of the upper part of the upper detachable part of the mooring pile, and FIG. 5 shows a plan view of the upper part of the upper detachable part of the mooring pile. A planing plate is provided on top of this to provide full surface contact between the mooring pile rollers. A perforated top triangular plate as shown in FIG. 4 is used to lift the upper detachment of the mooring pile for installation, adjustment and removal.

  FIG. 6 shows a plan view of an adjustable mooring dolphin. An adjustable mooring dolphin connects the mooring pile to the floating structure. The adjustable dolphin is designed to accommodate the eccentricity of the position of the mooring pile due to construction tolerances. This is achieved by designing the connecting bolt so that the mooring dolphin can move both vertically and parallel to the floating structure.

  FIG. 7 shows a front view of an adjustable mooring dolphin that is perpendicular to the floating structure. The mooring dolphin is attached to the side of the floating structure by six studs, three on each side of the center of the pile. The adjustable mooring dolphin has an elongated groove for adjusting the position of the mooring dolphin in a direction parallel to the floating structure.

  FIG. 8 shows a front view of an adjustable mooring dolphin that is parallel to the floating structure. The arm portion of the adjustable mooring dolphin extends over the deck of the floating structure and is secured to a support bracket structure welded to the deck. The extended arm of the mooring dolphin structure has an elongated groove that engages a stud welded to the support bracket structure. This allows the mooring dolphin to be adjusted in a direction perpendicular to the side of the floating structure. While the mooring dolphin is adjusted in this way, the stationary studs on the sides of the floating structure are kept engaged.

  Once both the floating structure side and deck connecting studs are engaged, the locking nut is attached and tightened to complete the installation of the adjustable mooring dolphin.

Although the foregoing description and accompanying drawings relate to particular preferred embodiments presently contemplated by the inventor, it is understood that the invention in its broader aspects includes mechanical and functional equivalents of the elements described and illustrated. It will be.
