World Tunnel Congress 2017 – Bergen

Our attendance at the 2017 World Tunnel Congress in Bergen last month was a great success. New partnerships, new markets, and great exposure.

We got some great exposure to civil engineering and tunnelling markets—as well as the key people in those markets—both in Europe and internationally.

We were quite impressed by some of the new innovations on display, chiefly to do with ground freezing solutions and urban tunnelling designs.

Most importantly, we welcomed the opportunity to push some of our key developments and advances, with our managed pressure drilling system and in-situ stress testing (IST) by overcoring being particular highlights.

Thanks to all who spoke with us, and we look forward to next year’s congress.

In 1990 he became Principal Engineer, Mining Research with the Safety In Mines Testing and Resarch Station of the Department of Resource Industries of the Queensland Government. In this role he worked on frictional ignitions, mine explosions, windblasts, gas drainage and directional drilling including the first surface to in-seam operation in the country in 1991. In 1994 he started Sigra as a one man business. Since then the company has grown under his guidance to span mining, gas, civil, geotechnical work and a number of mechanical and electronic product developments.
