Definitions

  • the invention relates to a mooring system for mooring a vessel on the surface of a body of water comprising a mooring point having buoyancy and being anehored to the floor of the body of water 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 hill.
  • Such a mooring system is known from FR-A-2.420.475, fig.7 and 8.
  • the mooring point is a tower structure which is kept upright by its own buoyancy and anehored to the floor of the body of water by means of a universal joint.
  • the upper end of this tower 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 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 therof, 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.
  • the mooring point is a floating buoy having a limited lateral stability and anchored by means of anchor chains or anchor cables
  • the tension members are pivotable tension members such as chains of cables
  • the rigid arm structure is Y-shaped each vessel end therof being connected to a tension member, the arrangement being such as to allow a rotational movement around the longitudinal axis of the Y-shaped structure.
  • the invention is elucidated on the hand of the drawing.
  • the figure shows the vessel 1 floating on a body of water 2, and moored by means of two pivotable tension members 6, 7, a rigid arm 15 and a floating mooring buoy 3 which is anchored by one of more anchor chains 5.
  • the single point mooring buoy 3 is of a type known as such and consists of a 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 in this embodiment attached to the 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. Furthermore, the arrangement allows rotational movement of the rigid arm 15 around its longitudinal axis by virtue of the limited lateral stability of the mooring buoy 3. A less practical solution would be to incorporate an axial rotational connection in the rigid arm 15 such as the one indicated with reference numeral 10.
  • the rigid arm 15 is 6-shaped and the two side arms 11-12 incorporate ballasting arrangements 13, 14. This implies that the two side arms 11, 12 can be ballasted or alternatively deballasted, in which case rigid arm 15 can become independently booyant.
  • Two pivotable tension members 6, 7 such as chain or cables connect the two side arms 11, 12 to the vessel 1. These tension members 6, 7 run from the ballasting members 13, 14 upwards through hawses 19 to fixing points 22 on deck 21 of the vessel 1. Any rolling movement of the vessel 1 is thus smoothed out by the up-and-down movement of the side arms 11, 12 causing the middle leg of the Y-shaped rigid arm to oscillate about its axis.
  • a mooring hawser 18 connects the single point mooring buoy 3 to a fixing point 24 on deck of the vessel 1. This is not essential but provides both an additional mooring facility and a factor of safety in the mooring arrangement.
  • the product fluid is carried to the single point mooring buoy 3 by means of the submarine riser 16. It is then transported to the vessel 1 by means of the floating hose string 17.
