Abstract From the Canadian patent

A coupling between a vessel and a mooring device includes a pin and a receiving sleeve into which the pin may slide axially, the sleeve being swingably suspended and connected with hydraulic struts in a circuit with valves which can block the movability of the struts. The valves may be used to allow the sleeve to move freely during initial stages of the coupling process and then to cause, the sleeve to resist movement. An accumulator associated with the struts may be used to provide forces to centre the sleeve after coupling.
