The Green Alternative: Small Hydro Machines for Clean Energy
When you’re faced with a hard rock tunnel on your next small hydro project, which tunneling method works best? Intake tunnels can be at diameters as small as 2 meters and at steep grades of up to 45 degrees. Compared with the conventionally used method of Drill & Blast, small diameter tunneling machines offer increased production rates and reduction in cross section, among other benefits. The uniquely designed machines are engineered to take on steep gradients, and can bore tunnels kilometers long with minimal impacts to the surrounding environment.
In this complimentary, 60-minute webinar we discuss the use of small diameter tunneling machines on projects throughout Norway, where their popularity is increasing, as well as the method’s suitability on projects worldwide. Listen in on our conversation with Robbins Norway General Manager and Civil Engineer Sindre Log as we discuss recommendations for small hydro tunnels in hard rock. Join us for a live Q&A session at the end to get a thorough answer from our expert speaker.

Three Great Challenges: Experiences from TBM Tunneling in Difficult Ground
When boring through the earth, even extensive Geotechnical Baseline Reports can miss fault lines, water inflows, squeezing ground, mixed face conditions, rock bursting and other geological challenges. That reality is compounded when tunnels are extremely long, in remote locations, or under high cover.
In this lecture, Robbins’ President Lok Home will discuss three of the most challenging projects in recent memory: The 43.5 km long AMR Water Tunnel, the geologically diverse Sleemanabad Carrier Canal (both in India), and China’s Yin Han Ji Wei project in challenging rock bursting conditions.

TBM Tunneling in Karst Conditions
France’s recently completed Galerie des Janots was the scene of some unforeseen challenges. During excavation with a Main Beam TBM, crews encountered a stalagmite studded 8,000 cubic meter cavern, and also a 4,500 cubic meter cavity directly under the bore path. In addition to the two large and uncharted caverns, there were also karst cavities of a multitude of sizes found throughout boring. What exactly did the crew do to beat the odds and power through?
For the answer, be sure to listen in as Detlef Jordan, Robbins Sales Manager Europe, goes into detail about the obstacles, lessons learned, and recommendations for future tunnels in karst conditions.

Title: Small but Powerful: Compact Hydro Tunneling offers Renewable Energy Solutions
Boring Through 48 Fault Zones and 26 Bar Pressure
Difficult ground doesn’t begin to describe the challenges overcome at a recent tunnel in central Turkey. The breakthrough of a 5.5 m diameter Robbins Crossover XRE TBM at the Gerede Water Transmission Tunnel was a feat of modern construction. The 9 km leg was the final section of the 31.6 km long water supply line bored through what is widely considered to be Turkey’s most challenging geology: from 48 fault zones to water pressures up to 26 bar, the ground put the machine and the crew to the test.
Listen in on the conversation with Robbins Vice President Doug Harding as we find out how the unique TBM design and experienced crew overcame a gamut of challenges.
