Fast underwater stern tube seal replacement avoids need to drydock
Last month one of our diver/technician teams carried out underwater stern tube seal repairs on a 192-meter roro vessel in Rotterdam. The vessel was suffering from an oil leak, making a fast repair necessary. Our men carried out the entire operation on-site and underwater using a Hydrex flexible mobdock.
Every Hydrex office has a fast response center equipped with all the latest facilities, lightweight equipment and tools. These centers were designed specifically to increase speed of service. This allowed us to immediately mobilize a team on one of our workboats to the vessel’s location.
The operation started with a thorough underwater inspection of the stern tube seal assembly. The divers then removed the rope guard of the vessel and installed the flexible mobdock around the stern tube seal assembly. This created a dry underwater environment to work in drydock-like conditions, a necessity for permanent stern tube seal repairs.
After cleaning the entire assembly the diver/technicians removed the three damaged seals one by one and replaced them with new ones. Because the existing running area was damaged, the team also installed a spacer ring to create a new running area for the seals.
A service engineer of the OEM was present during the operation and gave his approval for the replacement.
Every day a ship has to go off hire causes a substantial loss of money. The team therefore worked in shifts to perform the stern tube seal repairs within the shortest possible time frame. This saved the owner the time and money going to drydock would entail.
