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.

On October 31, the SPE ICoTA Europe held its traditional "Lunch and Learn" event in Aberdeen. During this forum, representatives of IOC’s, NOC’s and oilfield service companies inform themselves about technical innovations, new processes or solutions to defined problems.

The only speaker at this event was Stefan Hasselmann, Product Line Manager at KOLLER. For about 30 minutes he spoke about the compact-E-drive, our new electric drive system for wireline and logging winches. Stefan talked about the reasons for the development, the project phases from the design over the construction of the prototypes to the field tests with customers. The audience followed attentively his remarks on technological advantages and savings potential of the new technology. A particular interest the listeners developed in the future-topic of automation. The individually programmable control of the compact-E-drive units offers many opportunities. From remote monitoring, through pre-programming of job or well parameters to full remote control, anything is possible. The prospect of being able to operate future system generations with battery clusters, including energy recovery, was also received with interest.

We are very proud that we were able to present our new development in front of a high-profile audience and thanks for the great interest. Special thanks go to the ICoTA team for the excellent organization of the event.
