At the end of 2022 our diver/technician teams carried out a double underwater stern tube seal repair on a roro ship berthed in Port of Burnie, Tasmania. The ship was leaking oil, making an on-site repair necessary. Using two Hydrex flexible mobdocks simultaneously the team was able to carry out the entire operation on-site and underwater in just 60 hours, saving the owner an expensive and time-consuming trip to drydock.
After arriving on-site, the diving team first set up a monitoring station next to the vessel. The operation then started with a thorough underwater inspection of the stern tube seal assemblies.
After the inspection the divers cleaned the assemblies and installed both flexible mobdocks. By doing this they created a dry underwater environment so that they could work in drydock-like conditions.
| With Hydrex organizing 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 he could sail his vessel to her next stop free of oil leaks. If ever you would encounter a similar situation, give us a call. We can then tell you if the repair is feasible and start working on its handling. |
