HTS Maskinteknikk works closely with customers in demanding sectors like subsea, defence and aerospace in the role of a mechanics subcontractor and partner.  Parts from the company’s production have found their way to the deepest subsea installations as well as to satellites bound for outer space. HTS Maskinteknikk, based in Drammen in the heart of the ‘Subsea Valley’ and close to the technological milieu in Kongsberg, supplies customers all around the world. Currently, approximately 50% of the company’s production is directly exported.



HTS Maskinteknikk specializes in high precision turning, milling and sophisticated welding related to its turning and assembly production. The impressive range of machines is among the most modern and extensive in Norway. More than fifty (CNC) numerical machines, many of them customized to make one or a few products, reflect a clear and targeted strategy. The company has always been willing to engage its resources in prototype production, but with its extensive range of machines and skilled people the company balances it with a constant flow of serial work at the same time.


After a massive wave of investments in buildings and machines several years ago resulting in, amongst others, the Deckel Maho department which features impressing milling precision and capacity, HTS Maskinteknikk has increased the number of dedicated turning machines for its subsea components during recent years.

Since 2011 the company has had nine new machines installed, and paired with its organic growth it has now reached a comfortable capacity level where it is prepared for continuous growth in the subsea sector. Furthermore, HTS Maskinteknikk has also made considerable investments within programming and has a good base of skilled programmers for five axis dynamic milling through the Mastercam tool that was installed last year.



The importance of quality welding has been increasingly emphasized in recent years, and HTS Maskinteknikk has definitely been at the forefront when it comes to investing in advanced welding equipment. The company’s welding is performed under laboratory-like conditions where the key factor for success lay in perfecting the repetitiveness controlling all the perimeters in order to obtain the best possible weld. The company approached Danish manufacturer Migatronic and had a custom made welding centre based on their special needs. The centre has a robot and two workstations providing both efficiency and great HSE advantages. After three years of service the company sees close to 0-defect capability in the welding process and thus the second machine was ordered. After only a few months in service HTS Maskinteknikk has now received a third welding machine and seems to be well prepared for market expectations for the years to come.

HTS has an extensive range of welding qualifications for various material-combinations utilized for the subsea industry, and in diameters up to 1 inch.

Control & Calibration

HTS has always put a lot of effort into control and inspection and its main control department has its flooring separate from the rest of the building to ensure maximum accuracy in the company’s measurements. In total, three CMM measuring machines offers the opportunity to the continuous serial measuring of finished parts as well as control during production. During 2013 the company also invested in a scanner and a profile measuring machine for efficient in process measurements. HTS has even invested in its own calibration machine to ensure calibration of its equipment and the company also does some calibration for other companies.



With over 6,200 square metres featuring operator-friendly working conditions, all processes, including NDT and pressure testing, are managed in-house in order to achieve cost effective and efficient logistics as well as a maximum of flexibility to support the company’s customers’ needs. 

HTS Maskinteknikk has a very dynamic organization and swiftly implements improvements that will become necessary in the future. A major ramp-up in personnel has been made during 2012 to better respond to the markets’ needs and what the future seems to hold.

HTS Maskinteknikk is proud to be a major mechanical actor with a base in Norway.
