Abstract:
Disclosed herein are embodiments of an offshore drilling rig comprising: a drill floor ( 107 ) defining a well center ( 123 ); a hoisting system configured to advance a tubular string ( 128 ) downwards through the well center ( 123 ) and to the seafloor ( 124 ) and to apply a lifting force to a tubular string ( 128 ) extending through the well center ( 123 ) and to the seafloor ( 124 ), the lifting force being large enough to support at least a major part of an apparent weight of the tubular string ( 128 ); and an anti-recoil system ( 218 ) 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 ( 128 ) while preventing damage to the hoisting system.

Claim (Index 16):
An offshore drilling rig according to  claim 1 ; comprising a riser tensioner system wherein the drilling rig is operable to perform well completion and/or intervention operations with a completion work-over riser system suspended from the hoisting system and with the riser tensioner system disconnected from said completion work-over riser system.
