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

Five years ago, the final shaft depth was reached at the Woodsmith Mine project, UK , with a #Herrenknecht VSM (Ø9.85m). The machine reached 115.2m and established a world record. This is the deepest shaft ever drilled underwater with a VSM. This experience has significantly boosted the development of our technology for deeper shafts. In total to date, 111 shafts have been sunk worldwide in 14 countries across four continents, covering a total of 5.580 linear shaft meters built, with the largest diameter being 12.9 m. This year, VSM is turning 20, so stay tuned on this channel to discover more projects! https://lnkd.in/d5kJwXi #pioneeringundergroundtogether

Early May, a #Herrenknecht EPB shield with a 3.78m diameter broke through in the Paris region. Just in time for the Olympics!!! The TBM was used to bore a 3.5 km tunnel aimed to transport wastewater to the water treatment plant from the Greater Paris Sanitation Authority (SIAAP). This is another step contributing towards improving the quality of the river Seine, where the triathlon athletes will soon swim. Some of our challenges were the narrowness of the reception shaft and tunnelling below the river Seine axes, with now and then a minimal cover/overburden of 6 meters. Thanks to our long-time partner JV Eiffage Génie Civil/NGE - BTP for their trust. #pioneeringundergroundtogether Credit: Eiffage & David Demieres

"Shanhe" is ready for transportation. The Mixshield tunnel boring machine is designed for the extreme conditions of the upcoming undercrossing of the Yellow River. A two-storey road tunnel with three lanes in both directions is to be built in the eastern Chinese city of Jinan. This Mixshield TBM, one of the largest ever built with a diameter of 17.5 meters, will tackle high groundwater pressure and a challenging geological environment. A machine of this diameter has only been used twice before in the history of tunnelling - the largest in 2015 in Hong Kong, also a Herrenknecht Mixshield ( ∅ 17.63 meters). The project aims to enhance connectivity for Jinan´s 9 million residents, improving traffic flow and supporting the ecological and economic development of the Yellow River Basin. We wish Jinan Urban Construction Group Co. and China Railway 14th Bureau Group Co. every success with the project.

The Thailand Underground and Tunnelling Group (TUTG) of the Engineering Institute of Thailand (EIT), in collaboration with #Herrenknecht Thailand, hosted a technical symposium in Bangkok last week. With 80 distinguished authorities, academics, contractors and young engineers in Bangkok and over 335 online participants, the event showcased cutting-edge advancements in mechanized underground construction. Local speakers discussed Thailand's underground infrastructure plans, while our Herrenknecht experts introduced our innovative solutions. We also presented our new production and service base in Rayong, near Bangkok: all attendees were invited to visit the impressive 9,500 sqm workshop on the next day. 110 visitors from Thailand and Australia were thoroughly impressed, marveling at the Ø6.6m TBM for Bangkok Metro and a Ø2.5m microtunnelling machine ready for underground cable tunnel works in Taiwan. Thank you to all participants and the co-organizer TUTG, the Thai Authorities and all stakeholders from the tunnelling industry for your support. We look forward to future local collaborations! #pioneeringundergroundtogether

Congratulations to the WestEnd Connectors Construction on the second and final breakthrough at the Eglinton Crosstown West Extension Project. After approximately 25 month of mining two 6.58m #Herrenknecht EPB shields completed both tunnels of the alignment for Metrolinx and Infrastructure Ontario. The extension of the Eglinton Crosstown LRT will run 9.2 kilometers from the future Mount Dennis LRT station to Renforth Drive and will operate mainly underground. Once complete, it will create a continuous rapid transit line that stretches from Scarborough, through midtown Toronto, and into Mississauga. #pioneeringundergroundtogether
