Epiroc Grey line paves the way at Vitberget wind park
July 6, 2024
Stephen Jakobsen, owner of S.G Bergboring, stands atop the rocky outcrop, surveying the landscape. His company has been entrusted with parts of the critical groundwork for the wind park. Within a period of eight to ten months, 800 000 cubic meters of rock will be removed. As the lead operator, Stephen is doing most of the drilling.
Enter the Epiroc Grey line drill bits—a revelation for Stephen and his crew. These bits are specifically designed with a focus on Cost Per Meter (CPM) efficiency, a crucial factor in construction and infrastructure projects. The Epiroc Grey line bits combines Epiroc’s renowned quality with CPM optimization.
”The rock conditions here at Vitberget are not really that tough. When I compare Epiroc Yellow line and Grey line bits here, Grey line does not lack in service life. Being able to use these new bits from Epiroc, has really opened up new possibilities for us. Overall drilling tool economy is so much better now. I’m very happy, it’s top notch!” –Stephen Jakobsen, Owner and lead operator S.G Bergboring
What does that really mean? Well, there's a big difference between drilling production holes, in difficult rock conditions underground and relatively short holes, in easy rock conditions on the surface. For S.G Bergboring, the latter is the name of the game. Given these rock conditions, Stephen has not noticed a lack of hole quality or penetration rate, compared to Epiroc Yellow line bits.
For S.G Bergboring, Epiroc is a total solution provider. So, not only are they using rock drilling tools from Epiroc, but also the machine driving the drill string down into the rock. At Vitberget wind park, Stephen is operating a SmartROC T40 drill rig. By utilizing both drilling tools and drill rig from Epiroc, operations are even better optimized.
"Our range of Epiroc Grey line bits is specifically developed for customers like S.G. Bergboring. The very positive feedback we have received from Stephen confirms that we align with our customers’ expectations. It assures customers that Epiroc can provide the best possible solution on the market for their specific needs."
Thanks to the benefits of the Epiroc Grey line, S.G Bergboring is able to take on more jobs such as the one at Vitberget wind park. These new drilling tools from Epiroc, are doing their part to accelerate the green transformation.
The Epiroc Grey line bits are paving the way, and the High Coast will continue to thrive. Stephen and the S.G Bergboring drilling crew know that they are part of something bigger—a transition toward a more sustainable world.
”When the conditions are right, as we can see on this project, Epiroc Grey line are a perfect complement to our Yellow line. Together with the customer, we can reduce the CPM while maintaining the same good hole quality, and reliable performance that Epiroc bits are known for. Giving the customer room for other needed investments whitout negatively affecting on the drilling results.” – Andreas Fredberg, Sales engineer Epiroc
