Caterpillar 3516 engine used as offshore fire pump package on a north sea oil platform needed to be maintained in line with the recommended service intervals.

This engine was due a top-end overhaul.


We carried out the overhaul which included change of cylinder heads, pistons, connecting rods, liners, fuel injectors, water pump, oil pump, fuel transfer pump and turbochargers.

During the overhaul, inspections were carried out on the crankshaft, camshaft, followers and bearings.


The Caterpillar 3516 engine overhaul was completed on-time and within budget, using 2 engineers on days and 2 on nights to enable 24-hour working.

In supplying the spares, Bartech carried out additional inspections, ensuring there were no problems with the assemblies before they were despatched.

The old assemblies were overhauled on return to Bartech ready for the next engine overhaul.
