IN-SERVICE MAINTENANCE

MANUFACTURER’S SERVICE IS REPRESENTED BY:

— in-time delivery of the blocks and accessories instead of those which completed their service life;

— operation servicing on the ‘on condition’ basis;

— theoretical and practical training of customer’s specialists at the manufacturing plant or under the field conditions at any point of the world; the information obtained by the customer’s specialists prevents from making mistakes when servicing our equipment;

— providing a spare engine to the customer to ensure the continuous functioning of the power generating unit during overhaul of the customer’s engine.

— sending manufacturer’s specialists to the customer for the time of power generating unit starting and, if necessary, for any time of operation.

IN-SERVICE MAINTENANCE

LOW OPERATION EXPENSES DUE TO:

— minimum capital expenditure for the operating site, fuel supply, electric energy reception;

— low cost maintenance;

— power self-supplying;

— long service life;

— high operation reliability;

— insignificant irretrievable oil losses;

— high level of equipment serviceability

HIGH SERVICEABILITY DUE TO:

— an easy access to the places of checking and adjustment;

— remote monitoring and diagnosis of the power generating unit equipment condition;

— a speedy trouble eliminating through availability of necessary tooling and appropriate spare parts set.

REPAIR SERVICING

— is supervised by the manufacturer

— the manufacturer provides for supply of the appropriate blocks and other equipment items for the running repair

— anticipates that the engine overhaul is performed at the manufacturing plant after which the original overhaul life is assigned

— proceeds from the manufacturer’s willingness to cooperate with the companies which wish to create their own repair facilities
