Definitions

  • the invention relates to a mooring system for mooring a vessel on the surface of a body of water.
  • the aim of the invention is to provide such a mooring system of which the parts are subjected to relatively small forces and loadings and which has a simple and sturdy structure.
  • Afirst embodiment of such a mooring system has the features as mentioned in claim 1 and a second embodiment has the features as mentioned in claim 2. Further embodiments are subject of the subclaims.
  • EP-A-0 096 445 (figures 4, 5) and EP-A-0 096 446 (figures 9, 10) both describe a mooring system of which the arms, which are each connected to a tension member at the side of the moored vessel hull can move independently with regard to each other in a vertical direction.
  • the vessel 1 is moored to the floor of a body of water 2 by means of two tension members 6, 7, a rigid arm 15, a standard type of single point mooring constituted by a buoy 3, and one or more anchor chains 5.
  • the single point mooring buoy 3 is of a type known to those skilled in the art, and consists of a buoy body 4 on which the turntable 8 is free to rotate about the vertical axis A A of the buoy body 4.
  • the buoy body 4 is attached to the floor of the body of water 2 by means of one or more anchor chains 5.
  • the rigid arm 15 is attached to the single point mooring buoy 3 by means of the hinges g. These hinges 9 allow relative movement between the buoy 3 and the rigid arm 15 about the horizontal axis B-B.
  • a first embodiment of the rigid arm 15 which serves as buffer or distance holder between a single point mooring buoy 3 and a tanker 1, for example a storage tanker.
  • the rigid arm has here the shape of a Y and has at two locations a hinge, viz. a first hinge 10 in the middle leg 19 of the Y near the buoy 3, and a second hinge 21 at the other end of the middle leg 19 where the fork begins, consisting of two side-legs 11, 12.
  • the right hand side leg 11 and middle leg 19 are pivotable with respect to the left hand side leg 12.
  • Both side-legs carry ballasts 13 and 14 at their extremities coupled to tension chains 6, 7 running upwards to the vessel 1.
  • the second hinge 21 consists of a disc 22 and a centring pin 23, which is located in a bore 24 in the middle leg 19 of the Y.
  • the left hand side arm 12 on the Y is connected to the hinge 21 via an extension 26 connected to the disc 22; vide Fig. 1A.
  • the vessel 34 is moored to the floor of a body of water by means of two anchor chains 37, a rigid arm 36, a rotational table 38 and a structure (“tower") 31 rigidly attached to the seabed 33.
  • the rotating table 38 permits the vessel to swing freely around the tower 31 to take up the position of the least resistance to wind and weather.
  • the rigid arm pivots in relation to this rotating table around an axis x-x, through hinges 41, thereby allowing independent pitch motions of the vessel relative to the tower.
  • Hinges at the rigid arm end 42 and at the vessel connection point 43 allow for excursions of the vessel due to surge and sway. Roll motions of the vessel relative to the tower are allowed by two basically triangular frames 44 and 45, which are coupled together at their base and hence form the rigid arm 36.
  • the hinges and 48 allow the rigid arm to be “folded” in itself, around axis and thus allow independent roll between the towe-side end of the rigid arm and the vessel side.
  • the restoring forces required to balance environmental forces acting on the tanker is generated by a weight 49 which forms a part of the rigid arm.
  • This weight can be permanent or mobile, depending on the application of the mooring system.
  • the product is carried up the tower through rigid piping 50 to the top of the tower, where a fluid swivel mounted on a second rotating table 40 allows for orientation of the piping towards the vessel.
  • the piping continues to the vessel in a manner described in published patent application No. EP-A-0079404.
