Last month a Hydrex diver/technician team carried out underwater stern tube seal repairs on a 110-meter offshore supply vessel in Bunbury, Australia. The rope guard covering the stern tube seal assembly was missing and the seal box had come loose after a mooring rope got tangled around the assembly. An emergency on-site repair was necessary. Hydrex therefore mobilized a diver/technician team to the vessel’s location and was able to carry out the entire operation on-site and underwater. This operation saved the owner an expensive and time-consuming trip to drydock.
