Project Summary:

As part of the Reindeer field development, Apache Energy’s drilling campaign required three conductors to be mounted to their respective tensioner units simultaneously. AME also completed structural analysis review of the rig transom, to verify its suitability for the increased operational loads.

The tensioner deck was required to be easily folded up against the rig transom for transport and also certified, for an offshore lift during installation.

Due to the increased mass of the new tensioner deck, the rig cranes were not able to handle the structure. AME’s installation method utilised the rig’s 600T capacity draw works, to lift the deck directly from the supply vessel beneath the rig.
