Karsten Moholt was commissioned to fabricate a new bearing shield for a generator on land for Østensjø Rederi AS. The work was carried out by Karsten Moholt at our workshop in Bergen. The workshop is certified by DNV to perform this type of job.
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 converted the machines to an insulated bearing arrangement with a separate shaft grounding. This solution provided stronger insulation than coated bearings, and allows the use of standard bearings.
