At the end of 2022 Hydrex diver/technician 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.   The exact same procedure was followed on both stern tube seal assemblies. The split ring was first disconnected and brought to the surface to be cleaned. After cleaning the entire assembly, the divers removed the first seal and replaced it with a new one which was then bonded. This was done in cooperation with the supervising OEM technician. The procedure was repeated with the other three seals.   A successful operation was concluded with leakage tests, the removal of the flexible mobdocks and the reinstallation of the rope guards.   Long distance a stimulus, not a hindrance Despite the remote location of the ro-ro vessel, the Hydrex technical department was able to make all practical logistic arrangements and organize a mobilization of the equipment very swiftly. In the recent past Hydrex has carried out several operations in Australia. Earlier in 2022 they mobilized to the same location for an identical job on the vessel’s sister ship, so the customer knew they could perform the operation fast, safe and to the highest quality standard.   Taking advantage of the company’s flexible mobdock technique the team was able to carry out the entire repair on-site and underwater. Because all the required material is ready to be transported at all times, no time was lost making preparations.   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.

The U.S. Government Accountability Office (GAO) has pored over the U.S. Navy's ship repair records, and it has found significant long-term challenges for sustainment.
