KSMV was founded by Otto Hansen in 1918. From a modest start, the business has gradually evolved to becoming one of Norway's most advanced mechanical workshops. Today, we serve both national and international clients within a wide range of industries, with most of our customers within the Oil & Gas and Subsea segments.  We dedicate much of our success to a talented workforce with focus on continuous improvement, and willingness to invest in modern CNC machines.

KSMV was NS-EN ISO 9002 certified in 1994. At the same time, we were certified according to the NS-EN ISO 3834-2 welding quality requirements. We always follow the latest quality standards and are now certified according to the new EN ISO 9001:2015.
