摘要
A subsea marine conductor bending tool for bending lower portions of the marine conductor when in the sea adjacent a subsea wellhead to align the conductor and its coupling member to a subsea wellhead has a plurality of individual bending beam assemblies and means for connecting them together in an articulated vertical array, a running tool for running the array of beam assemblies down within the conductor from an overhead platform to lower portions within the conductor adjacent a subsea location to which the conductor is to be aligned and hydraulically operated means on each of the bending beam assemblies operable from the overhead platform for applying bending forces against adjacent interior portions of the conductor to bend the same as required to align the conductor and its end connector to the wellhead. The bending tool is run down into the conduit, the conduit is bent into an S curve while in the subsea environment and landed into connection to the associated subsea wellhead while being bent by the bending tool, hydraulic fluid pressure used for causing the bending tool to bend the conduit is then relieved after landing of the connector on the wellhead and the tool is then withdrawn from the conductor.
