We have upgraded the Bentec 350 - increasing the lifting capacity to 418 tonnes

Our company is pleased to announce a major modification to the Bentec 350, which will increase its lifting capacity from the original 350 to 418 tonnes. This move will allow us to better respond to the growing demand for heavy rigs that has arisen not only in the Oil and Gas sector, but also in the deep geothermal drilling sector.

Deep geothermal drilling is becoming increasingly popular in Europe. Traditionally, they are found in countries such as Iceland, Italy, Greece and the Azores, where conditions are favourable for the exploitation of geothermal energy. Nowadays, however, thanks to new technologies and the development of alternative energy sources, demand is also growing in other European countries such as Germany, France and Slovakia. However, Vermilion, which requested this modification to our rig, is primarily focused on oil and gas projects throughout Europe.

The payload modification will be carried out at the rig manufacturer in Bad Bentheim, Germany, and this challenging process will be mostly funded by Vermilion, which will use the modified rig on its very first well, the Weissenmoor South Z1 in northwest Germany. This well is very complex, the rig will move in as soon as the technical modifications are completed in October this year and the lead time is four to five months.

Modifications to the Bentec 350 rig include static calculations for new hook loads, fabrication of a new hoist and crown block with a larger load capacity, and procurement of a new service rope with a larger load capacity. In addition, modifications to the mast will be required, including welding of the stiffeners and modification of the pin connections, as well as modifications to the cellars, where the stiffeners will be welded and the connections between the boxes and the mast will be modified. The electrical modifications will be adapted to the new requirements and any changes will be documented. Finally, the rig will be newly type-approved by the LBEG (Landesamt für Bergbau, Energie und Geologie) with a lifting capacity of 418 tonnes.

We have also drilled for Vermilion in Croatia, for example, and are preparing joint projects in the Netherlands, Slovakia and France.

This upgrade is another step in our efforts to provide quality service and technology to our customers. We look forward to the new opportunities this upgrade will bring and to further successful projects for this rig, not only with Vermilion.

Ruda Jakubík - almost 50 years in MND!

Rudolf Jakubík joined MND by chance in 1977. After his military service, he worked in a bank, where, during a tour, he met the head of the information systems department at the MND in Hodonín among the visitors. One thing led to another, a job offer came along, and even a higher salary. Although the promised computers remained more of a dream for the time being, Ruda took a step that changed his life for the next 49 years.

How geothermal energy works

Renewable energy sources have become a key topic in recent years. Everyone is familiar with solar and wind power plants, but there is another source that stands out for its stability, reliability and minimal dependence on weather conditions. However, it is not talked about as much
. Geothermal energy – heat accumulated in the Earth's crust – is one of the most promising types of clean energy, especially at a time when the need for stable, low-emission sources is growing.

MND drills geothermal wells for Košice

After years of preparation, the geothermal project has finally begun. The idea of heating Košice with geothermal energy had been in the works for many years. The first surveys in the Svinica–Ďurkov area were conducted in the 1990s and confirmed the extraordinary potential of hot water several kilometres below the ground. However, at that time, there was a lack of funding and political consensus to implement the project.
