Background

A Caterpillar 3516 engine driving the offshore fire pump package on board a supply vessel had reached its scheduled overhaul interval. To keep this safety-critical equipment compliant and fully available, the operator called on Worldwide Marine & Power Solutions to carry out the work in line with the manufacturer’s recommended service intervals.

Scope of work

Our engineers carried out a complete overhaul of the engine’s main assemblies, including the replacement of:

• cylinder heads, pistons and connecting rods
• cylinder liners
• fuel injectors
• water pump, oil pump and fuel transfer pump
• turbochargers

In parallel, the team performed a detailed inspection of the crankshaft, camshaft, cam followers and bearings to confirm their condition and rule out any hidden wear before the engine was returned to service.

Quality control

Every replacement assembly underwent additional inspection in our workshop before dispatch, so that each component arrived on board verified and ready to fit, with no surprises during installation.

Outcome

To minimise vessel downtime, we organised round-the-clock working with two engineers on day shift and two on night shift. The overhaul was delivered on schedule and within the agreed budget.

The removed assemblies were brought back to our workshop and reconditioned, so they are now available as exchange units for the next overhaul, reducing lead times and costs for future interventions.
