An offshore drilling rig configured for lowering and/or raising a string of tubular equipment into a subsea borehole. The drilling rig includes a drill deck; a first hoisting system being adapted for raising or lowering a first load carrier along a vertical first hoisting axis, wherein the first hoisting system is supported by a first support structure extending upwardly relative to the drill deck; a second hoisting system being adapted for raising or lowering a second load carrier along a vertical second hoisting axis located apart from the first hoisting axis, wherein the second hoisting system is supported by a second support structure extending upwardly relative to the drill deck; and a joint operations well center on the drill deck. During joint operations, the first and second hoisting axes are preferably located apart from the joint operations well center.
