Engine inspection

Oil analysis

Based on an oil analysis, it is possible to determine whether wear parts are present in the oil. The oil is drained and sent to the laboratory. Here, the oil is extensively tested for different values: Copper, iron, lead, aluminium, tinner etc… In addition, the condition of the oil is also mapped out.



PowerPort has the most modern endoscopes, which we use to view the engine internally. With an endoscopy, the motor is checked internally without having to dismantle it completely. During the endoscopy photos are taken. The photos are processed in a report. Endoscopy is a quick and inexpensive way to determine the condition of your engine


Engine read out

PowerPort has professional equipment to read out your engines. Your motor will be read out by a professional mechanic. When the engines have been read out, an extensive report will be sent to you.


Repairing marine diesel engines, generator sets and gearboxes is our passion. We do not care where or when, if possible on location or in our own workshop. The PowerPort mechanics are flexible and motivated and carry out all possible work on your engine.
