Abstract: Mooring system, comprising a ship, a mooring device, a rigid arm between ship and mooring device, which arm at one end is connected to the ship or mooring device through the intermediance of a first weight loaded connecting element, which is swingably suspended, whereas according to the invention the other end is coupled to a second weight loaded connecting element, which by its weight is held in a predensioned state aginst an abutment, such that only after a certain shift of the ship the second weight starts to function. The points of attachment of the ends of the rigid arm with the weight loaded connecting elements can be past the respective centres of gravity of the weights.

Abstract: Mooring device comprising a tower fixed to the water bottom, a ship and two rigid connecting arms, which are pivotably connected about horizontal axes to a turntable on the tower and which each are connected at or adjacent their ends by weight loaded connecting elements to the ship. These arms extend in opposite directions so that the two springs, each comprising an arm, a weight and a connecting element counteract each other to obtain a desired force/travel curve, allowing a larger shift of the ship.

Abstract: An elongated floating device connected via flexible means to the bottom of the water in such a manner that the floating device can undergo displacements through the action of wave forces while a structure is provided for redressing such displacements. At least one heavy plate extends in a vertical plane transversely to the length of the floating device, and is situated at a level below water level at least as low as the bottom of the floating device, and is suspended from the floating device so as to be freely pivotable about a horizontal axis which extends transversely to the length of the floating device. The plate has flat vertical opposite surfaces that are unconfined and are freely exposed in all horizontal directions to the ambient water.

Abstract: Mooring device comprising a body at a distance above the bottom of a body of water such as a tower positioned upon the bottom of the water. The tower carries a downwardly extending construction loaded by a weight which construction can pivot about a vertical axis at the top of the tower and about a horizontal axis and at its lower end has been connected with a floating device such as a vessel by one or more rigid arms. The point of connection of the rigid arms with the weight loaded construction is located beyond the vertical axis of the tower seen in a direction away from the floating device.

Abstract: A fender surrounding a mooring body and comprising a weight-loaded structure suspended by flexible connecting members from a higher location of the mooring body, which connecting members according to the invention extend upwardly and towards each other towards a point at or adjacent to the vertical axis of the mooring body, such that upon impact by a vessel the fender is tilted and quickly generates a return force.

Abstract: The invention relates to a rotatable pipe coupling for a plurality of pipes comprising a plurality of annular bodies (1,2,3) which are concentric and in interfitted relation with respect to one another instead of being stacked upon each other.

Abstract: The invention relates to a buoy comprising a buoyant body with anchoring chains, a turntable on said body with a mooring for a ship. According to the invention the turntable has buoyancy as well and preferably takes part in the water displacement of the buoy. The bearing between turntable and body is preferably above water level between a central sleeve of the body and the turntable, accessible from above and located in the line from mooring point on the turntable to chain stopper on the body.

Abstract: A mooring system in the form of a floating body having storage capacity e.g. a tanker has been provided at one end, such as the bow with a forwardly extending arm having an opening through which a buoy can be lifted and placed with outwardly extending lugs upon supporting recesses of the parts of the arm which define the opening there between by moving the raised buoy forwardly and lowering it with its lugs in the said recesses. This allows a fast connection and disconnection, so that in case the tanker is in danger due to ice or bad weather, the tanker can move away. After return of the normal situation the connection can be restored easily by lifting the buoy out of the water and placing it in its supports without the need of operating additional locking means. A plurality of vessels having the same arm can be connected one at the time with this buoy.
