1. A coupling device comprising:
a first coupler member connected to a ship, the first coupler member having a first valve; a second coupler member connected to a hose, the second coupler member having a second valve; a fluid displacement body that comprises:
a ring-shaped first elastic gasket arranged in a first mating region between adjacent surfaces of the first and second coupler members, anda disk-shaped second elastic gasket arranged in a second mating region between adjacent surfaces of the first and second valves when the coupling device is in a closed state, the fluid displacement body arranged and configured to displace at least a portion of fluid from the first and second mating regions; and a volume defined between the ring-shaped first elastic gasket and the disk-shaped second elastic gasket and between the first and second coupler members, the ring-shaped first elastic gasket is delimited in a sideway direction by a coupler seal and disposed radially outside the disk-shaped second elastic gasket to limit the volume for accumulating residual fluid, the volume having an inlet conduit and an outlet conduit, each of the inlet and outlet conduits connected to an external fluid control and the inlet and outlet conduit being integrated in the first coupler member, wherein the first and second coupler members are configured to cooperate with each other, wherein each of the first and second coupler members are configured to connect to a fluid system and are configured to releasably fasten to each other, wherein the first and second valves are configured to cooperate with each other and are configured to control fluid flow through their respective coupler member, and wherein the external fluid control is configured to control drainage of a residual fluid in the volume prior to unfastening the coupler members. |
