Overhaul of the transformers in Singapore

Date: July 2009
Location: Singapore

The field service department of Karsten Moholt has performed a replacement of the coils in two transformers on the ship Ramform Explorer. During the maintenance the ship was at a dock in Singapore. The disassembly of the transformer took 20 hours, and the starboard transformer showed clear signs of a heat damage towards the yoke.
 
A lift was constructed to get the new windings down to the transformers. The windings were mounted on the transformers, and a high voltage DC insulation test was performed. The test showed good results.
 
The entire job was done in only four and a half days, which is significantly shorter than what is usual for a job of this type and size. The customer was very satisfied with Karsten Moholt, and has used our technicians for several other jobs since.
