Frequently Asked Questions
What is the CREG 645 & 646 Heavy EPB TBM (Dubai Deep Tunnel) engineered for?▾
Exported to Dubai Municipality for the Deep Stormwater Tunnel Project (DS233-02). Specially engineered with an 11.05m excavation diameter to bore through tough sandstone and siltstone formations in harsh desert coastal geology.
Does Global TBM Machinery provide onsite field engineering dispatch for operating the CREG 645 & 646 Heavy EPB TBM (Dubai Deep Tunnel)?▾
Yes. Global TBM Machinery offers onsite assembly guidance, laser steering calibration, cutter replacement training, and 24/7 technical field support.
Can I purchase the CREG 645 & 646 Heavy EPB TBM (Dubai Deep Tunnel) machines shown on this page?▾
These two machines are a completed reference project: built by CREG and delivered to Dubai Municipality in 2018. They are not units we hold in stock or offer for sale. We supply equivalent 11 m-class EPB TBMs — new-build, refurbished, or cutterhead-retrofitted — to the same or a revised specification.
What warranty and field support come with an equivalent machine?▾
A new-build or remanufactured equivalent carries a 12-month or 5,000-hour operational warranty on main drives, hydraulic motors, and PLC systems, plus global spare parts dispatch. That warranty covers the machine we supply, not the delivered reference unit.
