Method of connecting a conduit to a subsea structure
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 near the subsea structure, and adjusting the axial position of the conduit's end to facilitate a direct connection with the subsea structure. Additional steps include aligning the conduit's end with a connector on the subsea structure, 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 moving the conduit away from the subsea structure by adjusting its position. The tensioning member can be operated remotely, and the process includes decoupling the conduit from the subsea structure before pulling it away. Additionally, the patent includes a system for connecting a conduit to a subsea structure, comprising a tensioning member and a guide assembly to facilitate the movement of the conduit into or out of connection with the subsea structure. This system provides a practical solution for efficiently connecting and disconnecting conduits in subsea environments.
