Hydro vice - Our best seller in 2018

Teams of FOS and Koller in front of the new NC pump trailer

Thirty times 220 kN clamping force to improve the capabilities of oil and gas workshops in 2018. For many years we have been building this hydraulic vice for fixing downhole tools and other round workpieces. Over the years, we have expanded the program around it more and more. Now the hydro vice has become part of a mobile bucking unit. It can be used to make and break screw connections directly on the well site. Previously you had to go to the workshop, which consumes time and money.

ALTUS on factory acceptance test of their new 3-split offshore wireline units

Last week, employees of our valued customer ALTUS visited us for the FAT of their new offshore wireline units. Each of the two units consists of 3 modules. A winch container, a hydraulic power pack and a closed operator cab.

The customer requested to limit the weight of each container to 1,800 kg max, which enables access to offshore platforms with restricted crane capacities. Despite its low weight, the units were designed as double drum units with 59 kW of power, enabling the user to conduct unrestricted slickline work .

Of course, the units are DNV-GL and ATEX certified. After the customer-requested adjustments from the FAT have been carried out, the wireline units start operations in the Danish North Sea.
