CONDUCTOR GUIDE SYSTEM FOR OFFSHORE DRILLING PLATFORMABSTRACT OF THE DISCLOSUREA conductor guide assembly for conductors of an offshore well platformhaving a jacket with an interior pile for extending from a sea bed to above awater level which is over the sea bed. In accordance with one inventivefeature, a first guide mechanism comprising a plurality of vertically spacedsupports which hold the tubular conduits within the interior pile is assembled ina plurality of sections wherein the upper support of each section is providedwith removable bolt-on units for supporting the first guide mechanism assuccessive sections are jointed thereto. In accordance with another inventivefeature, a second guide mechanism comprises a pair of circular platespositioned to rotate within a lower deck opening and which are connectedtogether and define a plurality of passages for receiving the plurality ofconductors that extend in the interior pile. The connected plates aretemporarily attached to the lower deck for transport so that the second guidemechanism can be detached and rotated to align the passages with the intendedpositions for the conductors whereafter the second guide mechanism ispermanently attached to the lower deck. In accordance with another inventivefeature, a third guide mechanism comprising a plurality of radially extendingbeams is supported on an upper deck. The second guide mechanism also haspassages for access to the conductors and it too can be rotated into a positionof alignment with the conductors and thereafter permanently fixed to the upperdeck.-17-
