System for coupling two floating structures

摘要

The present invention relates to a coupling system for coupling two floating structures together. The coupling system is able to accommodate the relative rotational and translation motions between the two floating structures without becoming disconnected. Furthermore, the coupling system has an engagement and disengagement mechanism that may be implemented remotely and efficiently.

主权项

1. A system for coupling a first floating structure to a second floating structure, the system comprising:
a receiving member disposed on the first floating structure for receiving an engaging member, the engaging member adapted to engage with the receiving member when the receiving member moves relative to the engaging member; a first joint connected to the engaging member; a first arm having a first end and a second end, wherein the first end of the first arm is operatively coupled to the first joint,
in which the first joint is configured such that the engaging member is movable along planes that are normal to the longitudinal axis of the first arm; a second joint operatively coupled to the second end of the first arm; a second arm having a first end and a second end, wherein the first end of the second arm is operatively coupled to the second joint,
in which the second joint is configured such that the second arm is movable along planes that are normal to the longitudinal axis of the second joint; and a coupling apparatus disposed on the second floating structure for coupling to the second end of the second arm, wherein the coupling apparatus comprises: a hydraulic piston adapted to connect to the second end of the second arm; and a skid assembly connected to the hydraulic piston.
