To provide offloading connection equipment for constructing a pipeline safely, swiftly, surely, and reliably between a shuttle tanker and FPSO (a floating production storage and offloading unit) of a storage ship for submarine natural-resources.

In the offloading connection equipment, there are provided a connector 16, inclined boards 17, 17, a receiving table 19, a float-inhibiting means 20, a clamp 21, and a moving means 23. The connector 16 has a plurality of supply pipes 15 attached to the ends of a plurality of hoses 14 for communicating with a liquid storage tank. The inclined boards 17, 17 are placed facing to each other, and each has a dog-leg shape in its cross section to receive the connector 16, when it is dropped. The receiving table 19 is freely movable on a bed 18 in the direction orthogonal to the axis of the supply pipe 14 of the connector 16 received with the boards 17, 17. The float-inhibiting means 20 inhibits floating of the connector 16 received with the inclined boards 17, 17 on the table 19. The clamp 21 grasps the clamp protrusion 22 which is provided on the side of the bed 18 of the table 19, and below the connector 16 received on the table 19. The movement means 23 moves the connector 16 grasped by the clamp 21.
