A diesel power plant based in South America with Wärtsilä 12V32 and Wärtsilä 18V32 diesel generating sets recently approached RA Power Solutions.
A serious accident took place due to the failure of the cylinder liner, resulting in damage to various parts, including the lower and upper engine block of the Wartsila 18V32 engine. RA Power Solutions technicians carried out the investigation and observed that the upper and lower engine blocks had suffered severe multiple cracks with a total length of 2900 mm, along with casting damage broken into small pieces measuring 300 × 460 mm.
Various options were discussed, and it was decided to replace the lower and upper crankcases. The cost of replacing the damaged lower and upper engine block of Wartsila 18V 32 was exorbitant, with a delivery period of 9 months. RA Power Solutions proposed to repair the multiple cracks and damaged portions by metal stitching and the metal locking process.
