CONDUCTOR PIPE SUPPORT SYSTEM FOR AN OFF-SHORE PLATFORM

摘要

A conductor pipe support system for a bottom-supported offshore drilling rig, the conductor pipe support system including a guide member configured for supporting a conductor pipe against horizontal movement when the conductor pipe extends from a blow-out preventer downward towards the seabed; a support member configured for vertically supporting at least a part of the load of the conductor pipe; and an access platform for allowing personnel to access at least a bottom portion of the blow-out preventer system; wherein the support member is connectable to the conductor pipe below the access platform.

主权项

1. A bottom-supported offshore drilling platform comprising:
a hull and one or more legs extendable from the hull downward towards the seabed of a body of water so as to elevate the hull above a surface of the body of water; a cantilever comprising a drill floor and a well centre defined in the drill floor though which well centre drilling operations may be performed through a blow-out-preventer system located below the cantilever and through a conductor pipe extending from the blow-out-preventing system downwards towards the seabed; a conductor pipe support system comprising:
a guide member configured for supporting the conductor pipe against horizontal movement when the conductor pipe extends from the blow-out preventer system downward towards the seabed;a support member configured for vertically supporting at least a part of the load of the conductor pipe; andan access platform for allowing personnel to access at least a bottom portion of the blow-out preventer system; wherein the support member is connectable to the conductor pipe below the access platform.
