Since 1940, Goltens has been providing a full range of preventive and emergency repair services to our marine, industrial, offshore and stationary power customers throughout the world.

Goltens is a service organization that enables plant operators all over the world to minimize asset downtime.

Responding quickly to critical situations with services of predictably high quality has earned us a strong position with decision makers who focus on the value of uninterrupted operation.

Goltens performs in-situ services, which lead to reduced costs and downtime associated with equipment repairs.

Our specialism in diesel engine repairs also applies to engine room equipment.

Goltens is continually presented with new operational problems that also need to meet new environmental standards.

We work closely with leading equipment manufacturers. However, we are clearly independent to leave no doubt that our loyalty belongs to our customers.
