Recently, a Hydrex diver/technician team carried out an underwater stern tube seal repair on a tanker berthed in Tenerife. The ship was suffering from an oil leak, making an on-site repair necessary.

Using one of Hydrex's flexible mobdocks, the team was able to carry out the entire operation on-site and underwater. This saved the owner an expensive and time-consuming trip to drydock.

An earlier inspection had revealed that a rope had become entangled around the stern tube seal assembly. The rope was removed by divers but was found to have damaged the seals and caused an oil leak. The owner of the tanker requested replacementy of the damaged seals underwater so the vessel could maintin its schedule

During the operation the divers removed the three damaged seals and replaced them with new parts. The OEM supplied original spare parts which guarantees the best quality material. A technician from the seal manufacturer was present during the operation.

Hydrex says all offices are equipped with the latest facilities, lightweight equipment and tools. This allowed for a timely arrival of the team in Tenerife with everything needed to successfully complete the job. By organising everything from start to finish the owner did not have to worry about making any arrangements for the repair. After the seals had been successfully replaced the ship could sail to the next stop free of oil leaks.
