Underwater Repair and Maintenance

Providing a service that is both versatile and effective, Hydrex has built a reputation as the world’s leading underwater repair and replacement specialists. Building on an ever-expanding worldwide network of offices and support bases, Hydrex can provide fast service at reasonable costs.

The services offered range from an inspection of an external condition and any required maintenance work all the way through to highly technical major repairs or replacements of a ship’s external underwater equipment and machinery. 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.

Maintenance work like the replacement of anodes that are worn out can easily be carried out  without any interference with the vessel’s sailing schedule. Hydrex technical personnel work closely together with owners, managers and supervisors. All procedures and techniques used are fully approved by the major classification societies.

Hydrex is renowned for bringing highest quality repairs in drydock-like conditions to ships and offshore units. All operations can be carried out in port or while the vessel is stationary at sea. Normal commercial activities can therefore continue without disruption. This helps owners extend drydock intervals and eliminates the loss of time and production that drydocking entails.
