Abstract
Disclosed herein are embodiments of an offshore drilling rig comprising: a drill floor () defining a well center (); a hoisting system configured to advance a tubular string () downwards through the well center () and to the seafloor () and to apply a lifting force to a tubular string () extending through the well center () and to the seafloor (), the lifting force being large enough to support at least a major part of an apparent weight of the tubular string (); and an anti-recoil system () configured to cause, in case of a sudden reduction of a load suspended from the drilling rig, the hoisting system to raise the tubular string () while preventing damage to the hoisting system.
