Dokka Fasteners AS has recently invested in a new mega cell for its production facility in Dokka, Norway, which has enabled it to expand its product range and ensure consistent quality in every bolt manufactured.
Dokka’s mega cell contains full automation on hot forging, CNC machining, thread rolling and full non-destructive testing – such as ultrasonic inspection, hardness testing (with possible laser engraving of results) and magnetic particle inspection.
The company has also been through a process of automation, with 38 robots in manufacturing to make sure there is the same consistent product quality in each product. Additionally, all critical processes are kept in-house such as hardening, hot dip galvanising and quality inspection.
Dokka is able to manufacture high-tensile bolts up to M100 for a variety of applications. Recently, more than 8,200 M72 HV sets have been delivered to an offshore wind farm, where they are the fastening element between the monopile and transition piece – instead of a grouted solution. Another project is for one of the world’s largest oil and gas OEMs, where M100 riser and bonnet bolts will be fastening some of the most critical elements.
“Our bolts are often used in critical connections and/or harsh environments and it is important we deliver the best quality all the time. We are therefore glad our new mega cell enables us to respond to market requirements for constantly larger bolts, and at the same time continue with our consistent high-quality.”
