Definitions

  • the invention relates to a mooring system for mooring a vessel on the surface of a body of water, comprising a mooring point and a rigid arm structure connected at one end to said mooring point and at the other end to the respective, ballasted, ends of two tension members one on each side of the vessel hull.
  • Such a mooring system is known from French -A-2.420.475, Fig. 7 and 8.
  • the mooring point supports by means of a horizontal pivot axis two rigid arms which are at their respective other ends via respective horizontal pivot axes connected-to the vertical tension members of which the other ends are at the bow of the vessel interconnected by a further horizontal axis.
  • Such a mooring system allows a limited movement in the longitudinal direction of the vessel and provides a restoring force when the vessel moves towards the mooring point and away from it.
  • this mooring system is in fact a rigid structure so that rolling movements of the moored vessel impart very severe bending moments on the entire structure resulting in a heavy loading of the various parts and pivots and a rapid wear thereof, the more so because they are constantly subjected to the corrosive influence of the seawater.
  • the invention aims to provide an improved mooring system of the abovementioned kind which allows considerable rolling movements of the vessel without loading of the mooring point which can either be a mooring tower or a mooring buoy.
  • said tension members are independently pivotable with respect to the hull and the rigid arm structure comprises two parts to which the respective tension members are attached and the two parts can move independently of 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 thetur_ntable 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 9. 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 ofthe Y nearthe 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, 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 tower 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.
  • Fig. 3 is shown another embodiment of the tower or pile system 31 of Fig. 2.
  • the tower 60 consists of a number of piles 61, which are slanting and which are united in the upper part or top 62 of the tower, but spread out in the lower region near the sea bottom 63.
  • the rotatory part or rotor 64 of the SPM is connected to the rigid arm 66, the latter being connected with its other end via chains 67 to the vessel 68.
  • the product is carried up the tower through rigid piping (not shown) to the top 62 of the tower 60, where a fluid swivel 69 mounted on a second rotating table 71 allows for orientation of the piping 72 towards the vessel 68.
  • the piping 72 continues via sections 73-80 to the vessel 68.
