Company statement

High quality underwater repairs by trustworthy professionals

When we send a team to an operation, any operation, we have one goal in mind: to get the job done in the shortest possible time and to the highest standards. This has been our policy since Hydrex was founded in 1974. Our track record proves that this is not a false claim.

Turning divers into specialists

We want to offer the highest quality of service for our customers while at the same time guaranteeing the safety of our divers at all times. To  achieve this we need staff who have familiarity with a wide range of operations as well as the relevant know-how.  Our diver/technicians are trained and qualified to perform all class-approved repair procedures in even the harshest conditions.

This is a result of the stringent training all divers go through. Whether they work for the Hydrex main office in Antwerp or for one of the other offices. They are required to have internationally accepted commercial diver certificates and take high standard external courses, including safety and offshore courses. Besides this they also receive comprehensive in-house training.

Training consists of both theoretical classes and practical drills on the Hydrex premises. There they have access to a wide range of underwater tools and various other equipment, including three dive training tanks in which underwater welding and other repair work can be practiced.

In addition to these classes, new divers also get the opportunity to assist experienced Hydrex diver/technicians during operations. The training enables them to become experienced divers and technicians themselves and to take advantage of the technical know-how and practical knowledge Hydrex has accumulated for over 40 years.

One of the aspects the training focusses on is learning to be flexible during an operation. Our teams have to be able to respond to changes if the need arises. This is very important because they are the ears and eyes of our technical department during an operation. From the initial inspection all the way through to the final check-up of the repair, they are the ones underwater and on-site. It is vital that they can handle any kind of situation when their training is completed.

This means that if a shipowner needs assistance, we are able to send a team of certified diver/technicians to the vessel immediately without losing time. They can carry out both simple and complex jobs even in harsh circumstances. They do this uniformly without unnecessary loss of time, quality or safety.

Putting the customer first

The customer pays to get the best results without losing any unnecessary time. So that is what we deliver. The scope of work is agreed upon in advance and the owner is given a precise assessment of the duration of the operation. Our many years of experience with a wide array of underwater repairs enables us to make an accurate estimation of the needed time frame.

Trying to lengthen the job is unbeneficial for the customer as well as for us because it is in direct opposition to what we are trying to establish: a relationship based on trust and good results. We give clear answers to any questions we receive and we deliver what we promise.

Over the years we have not only built long-lasting relationships with our customers, but also with classification societies, OEMs and local support bases around the world. Correct and direct communication is an essential factor in establishing and maintaining a network you can rely on. This allows us to quickly arrange spare parts, an engineer from the OEM or any external equipment needed for an operation.

We understand how important it is for a ship to keep her schedule. Going off-hire for days or even weeks to have underwater repairs carried out or pay an unscheduled visit to a drydock costs a tremendous amount of money. That is why we have developed technologies that allow us to perform underwater repairs within a very short time and to drydock standards. Hydrex is renowned for bringing drydock-like conditions to ships and offshore units. This helps owners to extend their vessel’s drydock interval and eliminates the loss of time and production brought about by drydocking.


This is done with our mobdocks. Mobdock is short for ‘mobile mini drydock’. With this technology work below the water line is done by taking a small mobile drydock environment to the vessel, rather than by taking it to a shore based drydock. With the implementation of this technique Hydrex diver/technicians can perform permanent repairs to all parts of the underwater ship propulsion system, as well as steel work or crack repairs in drydock-like conditions.

Because of the nature of repair work, it is often necessary for solutions to difficult problems to be worked out in a short time period, sometimes even after an operation has already started. This can only be done successfully by people who have familiarity with such challenges and the relevant know-how to resolve these technical difficulties. This is why Hydrex has a technical department capable of executing all the required planning, an in-house Research & Development department that can take care of the engineering aspect of an operation and diver/technicians that are trained and qualified to perform the full range of required class-approved repair procedures in even the harshest conditions. We have found that an effective, competent team is the only way to consistently achieve a high quality result in the short periods of time usually available to ships with a tight schedule to maintain.

Through an ever-expanding, worldwide network of offices and service stations Hydrex can provide these start-to-finish solutions economically at any location. Headquartered in the Belgian port of Antwerp, we have offices in Tampa (U.S.A) and  Algeciras (Spain). And the list is growing as the demand for cost-effective localized services increases.

All Hydrex offices have fully operational fast response centers where an extensive range of state-of-the-art equipment is available at all times for immediate deployment with our skilled diver/technician teams to wherever they are needed.

All this is done to make sure that Hydrex is always prepared for all operations, including those that present unexpected conditions.

Contact us 24/7 with your underwater ship repair needs, routine or emergency, and we will help you get under way again rapidly without the need of a costly drydocking.
