ABSTRACT:
A conductor guide assembly for conductors of an offshore well platform having a jacket with an interior pile for extending from a sea bed to above a water level which is over the sea bed. In accordance with one inventive feature, a first guide mechanism comprising a plurality of vertically spaced supports which hold the tubular conduits within the interior pile is assembled in a plurality of sections wherein the upper support of each section is provided with removable bolt-on units for supporting the first guide mechanism as successive sections are joined thereto. In accordance with another inventive feature, a second guide mechanism comprises a pair of circular plates positioned to rotate within a lower deck opening and which are connected together and define a plurality of passages for receiving the plurality of conductors that extend in the interior pile. The connected plates are temporarily attached to the lower deck for transport so that the second guide mechanism can be detached and rotated to align the passages with the intended positions for the conductors whereafter the second guide mechanism is permanently attached to the lower deck. In accordance with another inventive feature, a third guide mechanism comprising a plurality of radially extending beams is supported on an upper deck. The second guide mechanism also has passages for access to the conductors and it too can be rotated into a position of alignment with the conductors and thereafter permanently fixed to the upper deck.
