Congratulations to Catherine, Eileen, Peggy and Marlene! The four #Herrenknecht tunnel boring machines (TBMs) have successfully completed their journeys, building rail tunnels for the Sydney Metro – Western Sydney Airport project. The new metro railway will become the transport spine for Greater Western Sydney, connecting communities and travellers with the new Western Sydney International (Nancy-Bird Walton) Airport and the growing region. Double Shield TBM Peggy (⌀6.96 m) made a smashing entrance at the newly named Bradfield Station at the beginning of June. Double Shield TBM Eileen (⌀6.96 m) reached Bradfield on May 29, completing the 5.5-kilometre tunnel from Airport Business Park to Bradfield. EPB Shield TBM Catherine (⌀6.95 m) finished her 4.3-kilometre tunnelling journey from Orchard Hills to St Marys on May 20. EPB Shield TBM Marlene (⌀6.95 m) made her final breakthrough at the end of June. The TBMs have excavated 1.86 million tonnes of material and installed 69,966 concrete segments to line the new tunnels. Congratulations to the tunnelling contractor team CPB Contractors Ghella for this significant achievement. #pioneeringundergroundtogether #herrenknecht

Celebrating 50 years of the Elbtunnel! Between 1997 and 2000 Herrenknecht was part on this amazing project too with Mixshield TRUDE! It excavated the 2.56 km long fourth tube of the Elbtunnel The challenge called for the expertise of Herrenknecht engineers, who faced high water pressures of up to 5.5 bar and varying ground conditions with cover depths of just seven to 13 meters. TRUDE was the world’s largest tunnel boring machine at the time, with a diameter of 14.20 meters. Conventional tool changes were impossible, leading Herrenknecht to develop special cutting wheel spokes accessible under atmospheric conditions. The active center cutter could advance up to 600 mm ahead in front of the cutting wheel, thereby improving tunnelling through the extremely cohesive soil. Additionally, the SSP system (Sonic Softground Probing) was first used with TRUDE to detect large obstacles, like boulders, in the tunneling path. The project and the technology used set new standards for mechanized tunnelling for years to come. Today, the TRUDE cutting wheel can be found in the courtyard of the "Museum der Arbeit" in Hamburg!

This is the continuation of a story that began in Spain in 2005. Its job at the time was to excavate a tunnel for the M-30 city highway in Madrid. After the project ended, the machine was put on hold for more than 15 years. Since summer 2022, a new chapter is being written for the TBM in Poland.   Its new mission: two tunnels, each 2,258 meters long, for the new S19 expressway between Rzeszów and Babica. The TBM has been owned by contractor ACCIONA since its deployment in Madrid (2005-2006). The machine has been made fit for reuse at the company's technology park in Noblejas (Toledo) since spring 2021 to adapt it to the requirements of the Polish project, conducted together with Mostostal Warszawa S.A. One of the adjustments immediately apparent is a new one-piece cutting wheel. In addition, a number of improvements were made, such as replacing the previous system for injecting the annular gap grout with a modern two-component system, installing a quick-unloading system for the segments and assembling the segment ring in semi-automatic mode. We wish the teams every success!!! #pioneeringundergroundtogether #herrenknechtag

The Herrenknecht subsidiary in Thailand reached a significant milestone with the successful Factory Acceptance Test for the Mass Transit Tunnelling Project “MRT Purple Line Project: Tao Pun-Rat Burana (Kanchanapisek Road) Section.” This achievement was marked by an official ceremony on 28th June 2024, reflecting the hard work and dedication of all parties involved. Two 6.55m Herrenknecht tunnel boring machines will help to extend the existing metro line system in Bangkok with a tunnel length of 3,201m each. We wish the entire team of Unique Engineering and Construction Public Company Limited a smooth and successful project. #pioneeringundergroundtogether #herrenknecht

Congratulations to GCR Mongolia for reaching the bottom of shafts at the Oyu Tolgoi project in May 2024! The project utilized four Shaft Drilling Jumbos, manufactured by Herrenknecht with impressive diameters ranging between 10.6 and 11 meters. The shafts, numbered 3 & 4, are among the largest ventilation shafts in the world, and the recent breakthrough marks the successful completion of the main sinking phase. Oyu Tolgoi, located in the southern Gobi Desert, is one of the most significant copper and gold deposits globally. Learn more about Shaft Drilling Jumbo here: https://lnkd.in/eM_mQQ-D

We’ve recently had the privilege in delivering a new Herrenknecht RBR600VF to a valued Australian client. It was a pleasure working closely with the mine owner, contractor, and the wider Herrenknecht team to ensure the Raise Boring Rig was delivered to all parties’ expectations. Upon the Rig’s arrival to site, the RBR600VF was set up to complete its first raise, a 5m diameter x 580m deep ventilation shaft. Having now just completed the reaming process of this first shaft, feedback from the client was that “the RBR600VF performed exceptionally for the project in both the piloting and reaming phases of the hole. The drillers were impressed with the performance of the RBR600VF and the ease of operation with the advanced rig console. The technical support from Herrenknecht from commissioning to operations was fantastic”. The RBR600VF is a powerful rig, capable to reaming shafts with a depth of up to 1,200 meters and diameters of up to 7 meters. Setup with three variable frequency controlled electric motors with a total power of 540kW, the drive achieves a maximum torque in reaming mode of 568kNm and a peak break out torque of 776kNm. The four hydraulic cylinders generate a thrust force of 10,000kN, enabling the rig to cut hard rock with ease. #pioneeringundergroundtogether #herrenknecht

Have you ever wondered how many truckloads are needed to transport a tunnel boring machine? The Double Shield TBM "Wilma" has an impressive diameter of 10,370 millimeters and a weight of around 2,700 tons (both figures include the back-up). With a length of about 183 meters and approximately 80,000 individual parts, it takes up to 170 truckloads to transport the machine! The heaviest component, the cutterhead center for the "H53 Pfons – Brenner" section, was recently transported from the Herrenknecht factory in Schwanau to Austria. This part alone weighs around 97 tons! Some machine components being transported are up to 6.60 meters wide. This means three cars could fit side by side within the width of one of these components. After three months of construction in the assembly cavern, in August "Wilma" will begin its journey towards Innsbruck. #herrenknecht #pioneeringundergroundtogether

The first foundation has been installed at the Yeu-Noirmoutier offshore wind farm in France, using Herrenknecht Offshore Foundation Drilling technology! We congratulate DEME on reaching this milestone with the specialized drilling designed for rocky seabeds, drawing on their expertise from the Saint-Nazaire project. For the new wind farm, OFD will be used to drill boreholes for 61 monopiles in the rocky Atlantic seabed between the islands of Noirmoutier and Yeu. Each monopile has a diameter of 7 meters and will serve as the foundation for one of the more than 200-meter-high wind turbines. This 488 MW project, spearheaded by Les Éoliennes en Mer Services and OW Ocean Winds (a joint venture between ENGIE and EDPR), will generate enough renewable energy to power nearly 800,000 French homes. #pioneeringundergroundtogether #herrenknecht https://lnkd.in/eU_3PJNk

Mid-June, it was our pleasure the welcome the Philippine Tunnelling Society (PTS), official member of the ITA, at our facilities in Thailand. Mark Wallace, President of PTS and Director of Infrastructure for ARUP, led the delegation. The tour was an opportunity to present our workshop facilities, capabilities, and latest innovations from the traffic and utility tunnelling product lines. Thanks to all involved for making it a useful and memorable visit. #pioneeringundergroundtogether

30 years ago, together with HOCHTIEF we achieved a still valid record to date at the EUROPIPE project: the largest and longest tunnel pipejack ever attempted from a single drive shaft. The #Herrenknecht slurry TBM successfully bored in one go 2,6km at the north coast of Germany. The tunnel provided the landfall connection on the German side for a new natural gas export pipeline from Norway. The tunnel lies some 6 to 8m below the surface and was needed to protect the coastal mud flats in the area which are part of an environmental sanctuary and national park. At high tide, the sea rises to about 15m above the tunnel exerting a potential 1.5 bar hydrostatic pressure at the tunnel level. Today, still impressed we look back at this adventure!!! #pionneeringundergroundtogether
