On-Site Crankshaft Machining

On-Site & In-Situ Crankpin Machining

Diesel engines are prone to failure, especially after many hours of running. The damage can range from bearing failure leading to some form of crankshaft damage to a conrod or balance weight blasting its way out through the side of the engine, causing serious problems.

The problem for the operator is much the same – downtime and large repair bills.

We Can Repair Your Damaged Crankshaft On-Site

Nicol & Andrew have been machining and repairing Marine and Industrial crankshafts in situ since 1950. In fact, we invented and patented an orbital machining system back then and have been improving it ever since.

You could say our current system of on-site orbital machine tools has been 70 years in the making.


Crankpin and Main Journal Repair Technicians

If you do end up with a problem with your engine it is almost a certainty that we have come across it before and have a solution to it.

Our crankpin and main journal repair technicians have to be highly trained to carry out onsite work. This training takes many years to complete and their ultimate level of skill is quite frankly amazing. It has to be this way, as there is no margin for error when machining a crankshaft on-site.

We have very capable supervisors and teams of technicians who love to get involved with refurbishment of crankshaft, crankpin and main journal bearings, on land-based sites and also onboard sea-going vessels.

We also have off-shore trained engineers who are able to travel anywhere in the world to offshore platforms.
