Advantages by using a G&O service

A well and correct functioning vibration compensator will remove damaging vibrations from the ship’s hull, tanks, structures and components. It provides a safeguard from vibration-induced cracks in the structure, bearing failures etc. and is often protecting the vessel from leaking gases, fluids from the cargo or other tanks as well as keeping electronic equipment from vibration-related malfunctions and thus keeping essential equipment in operation. 

The G&O guarantee

A further advantage of using Gertsen & Olufsen original parts or services is the service promise that we can provide. We pride ourselves of the quality of our parts and services. With every part or service provided from us, you will receive an 18-month guarantee and in some cases, an extended guarantee can apply.

G&O Service centers

With numerous service centres around the world, there is always one near you. Each service centre is capable of providing several Gertsen & Olufsen services, holds a variety of original spare parts and in most cases even replacement components.

Furthermore, the local service technicians have been trained according to Gertsen & Olufsen standard.

This means that we always respond fast in cases of emergency. 

G&O Original Parts

Gertsen & Olufsen utilizes state of the art technology and components to manufacture our compensators. The same high quality applies to our spare and wear parts.

Introducing original Gertsen & Olufsen spare parts into the maintenance programme of your compensator will enable your compensator to operate safely and according to specifications. 

G&O Original Services

The G&O services have been built up over decades. The service technicians, engineers, know-how and tools that Gertsen & Olufsen have at our disposal is second to none.

The services provided by Gertsen & Olufsen cover a wide range of offers that can be adapted according to individual needs.

Service contracts

With a service contract from G&O, the operation and maintenance of your vibration compensator are guaranteed. Depending on the service provided we can provide the inter-service period guarantee thereby making sure your compensator is always working properly. Most of our services can either be delivered ad-hoc or scheduled according to a service contract.


We continuously improve or develop our compensators and compensator control system. Furthermore, some components, in particular electrical ones, get outdated with an ever-increasing speed that creates the need for an update of the equipment due to lack of expensive spares. 


Vibration patterns change over time. To provide the necessary protection, it pays off to re-calibrate the compensator from time to time, particularly if major changes occur in the planned routes, cargo, speed or other operational parameters of the ship change. Recalibration is often done in connection with our service teams performing other services.

Refurbishment of G&O compensators

Gertsen & Olufsen compensators are designed to exceed even the highest expectations. However, as with all heavy machinery, there comes a time when wear parts will need replacement to ensure continued high-level vibration protection.

We offer both factory and onsite refurbishment of our entire range of vibration compensators.

The on-site refurbishment makes an ideal opportunity to recalibrate the compensator according to the ships current condition to enable the best possible protection.

Compensator rotation programmes

In some cases, a service, refurbishment or part replacement takes more time to perform than the actual time available alongside. For these special cases, Gertsen & Olufsen has developed the premium compensator programme.

The service suggests replacing the current compensator with another. Naturally with a full premium guarantee from Gertsen & Olufsen. This operation is far less time consuming and, in most cases, less complex than doing the actual onsite service.

The vast number of years of experience and the many references of Gertsen and Olufsen provides a unique opportunity to maintain a rotating stock of new and refurbished compensators for this purpose. All compensators come with a Gertsen & Olufsen premium quality guarantee.

The compensators are used for special service contracts.


Gertsen & Olufsen utilizes state of the art technology to manufacture our compensators as well as the parts within them. The same goes for spare and wear parts.

Introducing original Gertsen & Olufsen spare parts into the maintenance programme of your compensator will enable your compensator to operate safely and according to specifications.
