O&J Energy offers total solutions within repairs, monitoring and regulation of generators in the oil and gas industry, the windmill industry and the maritime industries. Service projects can take place in our workshop with high-tech facilities for troubleshooting and test beds for test and documentation, or on site whenever that is regarded as necessary. After repairs and overhauling, generators appear as if they were new. A full load test of generators up to 630 KW ensures and documents the integrity of the performance.
