A recently granted patent (Publication Number: US11867322B2) discloses a method for connecting a conduit to a subsea structure. The method involves providing a tensioning member on the conduit, deflecting a portion of the conduit to create a curvature, maintaining the curvature with the tensioning member, engaging the conduit with a guide assembly adjacent to the subsea structure, and releasing tension in the tensioning member to adjust the position of the conduit for a direct connection with the subsea structure. Additional steps include adjusting the guide assembly for alignment, locking the guide assembly in place, and fluidly coupling the conduit to the subsea structure. The tensioning member can be operated by various means such as a remotely operated underwater vehicle or actuators.
Furthermore, the patent also describes a method for disconnecting the conduit from the subsea structure, involving the use of a tensioning member to pull the conduit away from the structure. A guide assembly on the seabed assists in guiding the conduit during the disconnection process. The system for connecting the conduit to the subsea structure includes the tensioning member and guide assembly, allowing for controlled movement of the conduit for connection or disconnection. Overall, the patent presents innovative methods and systems for efficiently connecting and disconnecting conduits from subsea structures, with a focus on precise positioning and alignment for seamless operations in subsea environments.
