CENTOR's Gold Line Main Bearing Grease and Shield Tail Sealant were specified across a fleet of 8 mixed-face EPB TBMs boring through London Clay and Terrace Gravels. The project achieved a record advance rate of 92 m/week with zero lubrication-related stoppages over a 42-month drive.
Dual 11.6 m EPB drives through dense urban environment. CENTOR Gold Line soil conditioner and main bearing grease specified for 12.4 km total drive.
Highway · EPB TBMFull Gold Line specification for 4 EPB TBMs boring through Melbourne's mixed-face geology — basalt, sandstone, and siltstone formations.
Metro · EPB TBMCENTOR Silver Line products specified for 6 concurrent TBM drives. Technical support team stationed on-site for full duration of tunnelling works.
Metro · EPB TBMOne of the largest-diameter submarine tunnel TBMs ever deployed in Asia. CENTOR provided full Gold Line lubrication package and on-site engineering support.
Highway · Slurry TBMSlurry TBM drives in highly abrasive sandstone. CENTOR cutting tool grease reduced cutter wear by an estimated 18% versus prior-project benchmarks.
Metro · Slurry TBMShield tail sealant and main bearing grease supplied for 4 EPB drives in challenging sabkha and loose sand conditions approaching Expo 2020 site.
Metro · EPB TBM16 TBMs operated simultaneously. CENTOR managed centralised bulk supply and technical documentation for the entire fleet under a single supply agreement.
Metro · EPB TBMCENTOR Silver Line hydraulic oils and bearing greases deployed across 4 hard rock TBMs driving through Alpine granite at depths exceeding 2,000 m.
Rail · Hard Rock TBMTwin-tube metro circle line. CENTOR biodegradable soil conditioner foam approved by Copenhagen municipality for groundwater protection compliance.
Metro · EPB TBMEurope's largest urban rail infrastructure programme. CENTOR Silver Line products used across 11 TBM drives with full technical documentation and MSDS support.
Metro · EPB TBMSections 2 and 3. CENTOR Gold Line main bearing grease and anti-wear hydraulic oil deployed for drives under Wilshire Boulevard.
Metro · EPB TBMCENTOR Gold Line shield tail sealant and segment mould release agent deployed for twin-tube tunnelling through Toronto's downtown core and pre-Cambrian granite.
LRT · EPB TBMCENTOR's main bearing grease outlasted our previous specification by a significant margin on the Singapore NSC project. Their on-site engineer was invaluable during the difficult mixed-face reaches.
We specified CENTOR across our entire Doha Metro fleet. The logistics coordination and consistent product quality made managing 16 simultaneous TBMs far more straightforward than we anticipated.
The biodegradable soil conditioner foam was critical for our environmental permit in Copenhagen. CENTOR's documentation support made the approval process with the municipality efficient and straightforward.
