Riser deflection mitigation
Techniques and systems to reduce deflection of a riser extending from an offshore platform. A system may include a riser restraint device configured to be coupled to riser of an offshore platform. The system may also include a tether configured to be coupled to the riser restraint device. The system may further include a ratcheting system configured to be coupled to the tether, wherein the riser restraint device is configured to resist movement of the riser via selective retraction and extension of the tether from the ratcheting system.
