The vibration course was held for the crew at Stena Drilling The course combined theory and interactive tasks with Pruftechnik instruments. After completing the course, the participants had a good understanding of why we monitor the condition of rotating machinery (and other critical components), the importance of improved predictability and how vibrations can be properly measured and analysed to provide an early warning for a wide range of common errors.
Stena Drilling had problems with low insulation resistance on transformers on board the rig Stena Don. In the field, Karsten Moholt cleaned, dried and insulation painted the transformer windings on the transformers with too low insulation resistance.
Karsten Moholt 3D scanned hull plates at Statsraad Lehmkuhl that were due for replacement. Production drawings for new hull plates were made based on the scan. By using 3D scanning the measurements were made in approximately 10 % of the time compared to manual measurements.
