KOLLER hands over the first mobile workover rig to OMV Petrom
This workover unit is the result of many months of work. All departments from engineering over planning to manufacturing have given their best to meet the requirements of OMV Petrom S.A. located in Romania for this project.
After extensive tests, including tests performed by independent 3rd parties the goal was achieved. We can proudly announce that RIG90 with serial number 1001 has left Celle and was handed over to the customer on 27 April in Ploiesti, Romania. Further tests will be carried out under field conditions before final commissioning beginning of June 2015.
