CRANKSHAFT REPLACEMENT AND OVERHAUL:

Goltens started with the disassembly of the engine removing the condemned crankshaft, liners, pistons and marine heads out of the engine room. These major items were all taken to Goltens workshop in Rotterdam for detailed inspection.

Goltens arranged for the delivery of the replacement crankshaft and overhauled all parts including the turbocharger and air cooler in its workshop.

With specially designed hydraulic tools, Goltens removed the flywheel hub from the crankshaft and reinstalled the flywheel hub on the replacement crankshaft.

The engine’s camshaft was also fully inspected including full calibration measurements to the bearing pockets and bearing shells.

REASSEMBLY AND COMMISSIONING:

Goltens then completed the full reassembly of the engine inclusive of assembly of the flexible coupling and laser alignment and chocking of the engine

Engine commissioning and dock trials were followed by successful sea trials to the full satisfaction of the owner and class surveyors.

Once again Goltens provided a complete, one stop solution to the customer and provided advice and assistance to the insurance company throughout the process.
