Definitions

  • the present invention relates to a method for coupling a manoeuvrable vessel to a floating structure.
  • Such a method is known from EP0670392A1 wherein a device is disclosed having a conduit coupling whose one coupling part extends at the outlet of a pressure conduit of a suction dredger over the bow.
  • the other coupling part of the device is provided as a floating hose conduit formed as the end of a flushing tube conduit.
  • a pickup line is coupled to the floating hose. Upon hauling in of the pickup line, the one and the other coupling part are brought together and coupled for transport of dredge under pressure.
  • the known method for coupling is disadvantageous since while manoeuvring the vessel, sight to the floating hose and pickup line is poor. As a result thereof, damage may occur or coupling procedures may take more time, in particular under severe weather and heavy sea conditions. In addition, the known method is cumbersome and unsafe for personnel. This is particularly true in coastal waters in stormy weather and rough seas.
  • a suction dredger transports dredge or soil from the bottom of a body of water, especially from the ocean floor near the coast to the shore over a greater distance and rinsed there a floating line for the recovery of land for tilling land.
  • the invention aims to provide a method to facilitate coupling of a manoeuvrable vessel to a floating structure, wherein the method is more safe for personnel and allows operations at more severe sea conditions.
  • Another object of the invention is to solve, at least partly, a problem associated with known methods for coupling of a manoeuvrable vessel to a floating structure.
  • Yet another object of the invention is to provide an alternative method for coupling of a manoeuvrable vessel to a floating structure. According to a first aspect of the invention this is realized with a method for coupling a manoeuvrable vessel to a floating structure, the method comprising;
  • the pickup system comprising a float
  • a manoeuvrable vessel comprising a coupling device for coupling the vessel to the floating structure, the coupling device comprising manoeuvrable coupling means on the manoeuvrable vessel,
  • the method provides an improved coupling wherein a distance between the floating structure and the vessel may be observed in order to prevent damage while still being able to provide a coupling connection between the manoeuvrable vessel, also referred to as coupling vessel, and the floating structure.
  • the method provides an improved window of operation with respect to e.g. heavy sea conditions. This enables an improved usability of costly equipment like a dredger hopper at sea.
  • manoeuvrable coupling means may be part of the float. Important is that a difference in vertical movement between the float and the vessel can be accommodated by manoeuvrable coupling means such that the float and the vessel do not bump.
  • the manoeuvrable coupling means may be part of the vessel and/or the float.
  • this is realized with a coupling system for connecting a floating structure a manoeuvrable vessel, in particular the bow of the manoeuvrable vessel, the bow coupling system comprising a pickup system and a coupling vessel, whereby the pickup systems comprises at least a float for buoyancy of the floating structure on a water surface and a float coupling means connected to the at least one float, which float coupling means extends from the float above the water surface, and whereby the coupling vessel comprises a coupling device having manoeuvrable coupling means for engaging the float coupling means of the pickup system, such that a coupling connection between the manoeuvrable vessel and the floating structure is obtained.
  • the coupling connection is obtained by accommodation of the manoeuvrable coupling means in the float coupling means. This even more facilitates to establish a coupling connection between the vessel and the floating structure.
  • the coupling device is articulated and comprises;
  • a trailing coupling device member configured to be supported by the vessel in a hingeable manner, and hingeably coupled with the leading coupling device member, and provided with a conduit coupling means
  • leading coupling device member and the trailing coupling device member are mutually hingeable between a retracted position and a extended position of the coupling device wherein the coupling means and the conduit coupling means are arranged with respect to the coupling device such that, in the extended position of the coupling device the coupling means and the conduit coupling means are remote with respect to each other and the coupling means extend toward the water surface, and in the retracted position of the coupling device the coupling means and the conduit coupling means are about vertically aligned.
  • the trailing coupling device member is hingeably coupled with the leading coupling device member at their respective coupling ends, the coupling means are situated at a free end of the leading coupling device member opposite its respective coupling end, and the conduit coupling means are situated at a free end of the trailing coupling device member opposite its respective coupling end.
  • the trailing coupling device member is configured to be supported by the vessel in a hingeable manner proximate the conduit coupling means and opposite its respective coupling end.

  • the pickup system is configured such that it may raise at least a part of the floating structure above the water surface. Whether this actually will happen depends. Important is that at least a part of the float moves in unity with the pickup unit, more specifically the manoeuvrable coupling means thereof. It is conceivable that the float is articulated and therefore in practice no part of the float will raised above the water.
  • the float coupling means is arranged at an upper end of the float. This facilitates sight of an operator of the vessel on the coupling means itself which even more facilitates to establish a coupling connection between the vessel and the floating structure.

  • the pickup system comprises a pair of erected elongate floats, and wherein the float coupling means and/or the orientation means extend between the floats. The pair of floats aid in stabilizing the pickup system and therefore facilitates in establishing a coupling connection between the vessel and the floating structure.
  • the floating structure comprises a floating conduit having a free end, and wherein the pickup system is coupled with the free end for raising the free end above the water surface.
