In February, Hydrex diver/technician teams carried out underwater stern tube seal repairs on a 139-meter container vessel in Port Everglades, Fla., close to the company’s office in Clearwater. The vessel was suffering from an oil leak, making a fast repair necessary. Using one of the company’s next generation flexible mobdocks the team was able to carry out the entire operation onsite and underwater, saving time and money for the owners. Hydrex said it constantly invests in the research necessary to continue to evolve repair techniques and procedures. Over the years the Hydrex R&D department has constantly improved the flexible mobdock (mobile mini drydock) technique to make it possible for Hydrex diver/technicians to perform permanent repairs on seals, thrusters and almost any other part of the underwater vessel without the vessel needing to go to drydock. Hydrex said its latest generation of flexible mobdocks allows it to carry out the replacement of virtually any type of stern tube seals very quickly onsite. These flexible mobdocks are stored at the fast response centers. Designed specifically to increase speed of service, these centers are equipped with all the latest facilities, lightweight equipment and tools. This allowed us to mobilize a team together with all the needed equipment to the container vessel’s location within the shortest possible time frame.

Hydrex offers fast on-site repairs in emergency situations. Its fast response team are ready to mobilize immediately to locations around the world for a wide range of operations. There are many events that can stop a ship from sailing. Ships with a leaking stern tube are often not allowed to enter ports. A vessel can be tied up after a collision or a malfunctioning rudder can prevent safe maneuvering. Going to drydock is obviously not an option in such cases
