Adjacent and below the derrick the traveling block guide rails continue to interface with an underhull guidance system. The
guidance system, consisting of a moveable trolley that can be tied into the LRP/EDP package, provides rigidity as the equipment is lowered through the splash zone.
A dedicated frame for linking the stress joint, and therefore the complete TRT/LRP/EDP package to the underhull guidance
system is made up and stabbed into the underhull guidance system via the access funnels at the drill floor level. The guidance frame can be retrieved from below the drill floor level and tracked up above the drill floor in order to engage the equipment to be deployed. |
