  • 245m complete (approx. 30%). Ground conditions are challenging resulting in a low TBM advance rate. Sticky clay conditions continue to block the TBM head resulting in increased downtime associated with manual clearing of the TBM head.  The following actions are being taken:
    • Increase slurry line suction pressure through the implementation of 2.2 pump early. Note: P2.3 failure has delayed the implementation of the above.
    • Alteration to the slurry injection arrangement in the cutter head – works underway to modify nozzles.
    • Implemented a detergent additive to prevent cut clay sticking together and blocking the head. Have adjusted these additives to include a Clay Cutter.
    • “Mud Doctor” attended site on the 30th Nov 2023. Additives being used are correct, advised to increase concentration.
