A bottom supported offshore drilling platform has a hull 102 with legs 103 extendable from the hull 102 towards the seabed and a cantilever 104 comprising a drill floor 105 and a well centre through which drilling operations may be performed through a BOP stack 108 installed below the drill floor 105 and through a conductor pipe 109 extending from the BOP stack 108 downwards towards the seabed. The platform also includes a conductor pipe support system 107 for a bottom-supported offshore drilling rig, comprising a guide member 118 configured for supporting the conductor pipe against horizontal movement when the conductor pipe 109 extends from the BOP downward towards the seabed; a support member 110 configured for vertically supporting at least a part of the load of the conductor pipe 109; and an access platform 114 attached to a side wall of the hull for allowing personnel to access at least a bottom portion of the BOP stack 108 installed above said access platform 114; wherein the support member 110 is connectable to the conductor pipe 109 below the access platform 114 and said support member 110 is suspended from the cantilever 104. A method of installing the conductor pipe support system is also claimed.
