Proper maintenance of your turbocharger is essential for its safe operation as it minimizes the possibilities of break-downs which can lead to technical, operational and commercial losses for the shipmanagement company.
Special attention must be given by the shipping company and the engine crew of the vessel to keep records of the overhauling intervals of each turbocharger and arrange its proper overhauling on time.

Apart from the regular overhauling procedure (dismantling, cleaning and replacement of overhauling kits), the disassembly of the turbocharger onboard presents an ideal opportunity to inspect all of its internal components, investigate the source of any findings in connection with the engine/turbocharger log and suggest the necessary courses of action to maximize its operational efficiency.

A normal overhauling procedure is described below:
1.  Checking the records of the technical data of the turbocharger and the, attached to it, engine, and discussion with the engine officers about any abnormal behavior of them.
2.  Dismantling of the required casings (air filter, air insert, gas admission), bearings, diffuser depending on the type of turbocharger, and rotor-shaft.
3.  Cleaning of the dismantled parts.
4.  Inspection of the cleaned parts according to manufacturer’s specifications (which can be visual or require a specialized method i.e. ultrasonic measurement of the thickness of the casings).
5.  Replacement of the required parts (after agreement with the client).
6.  Assembly of all the parts back to the turbocharger.
7.  Measurement of the clearances and checking compliance with the manufacturer’s limits.

Our technicians are always in communication with the engine officers of the vessels or the ship management representatives and, after completion of the inspection, the Chief Engineer is asked to verify our work by signing the relevant overhauling and measurements reports. Copies of these reports, together with a detailed inspection report including photos, findings, possible causes of the damage and recommendation remarks are sent to the ship management company after further investigation by our technical and general manager.
