Double On-site Seal Repair on Offshore Platform in Mexico
In August a team of Hydrex divers traveled to Veracruz, Mexico for a stern tube seal repair. The operation consisted of the underwater replacement of the damaged seals on both assemblies of a semi-submersible offshore platform.
The unit left the field after its project was finished and was berthed alongside to have repair and maintenance work carried out without docking. We were asked to perform the stern tube seal repairs during the available window of opportunity.
After the diving team performed a thorough underwater inspection of the assembly they installed on of our flexible mobdocks. Next they removed the four damaged aft seals one by one and replaced them with new ones. The two forward seals were also replaced during the repair. The six seals of the starboard side assembly were then given the same treatment.
Our lightweight flexible mobdocks are designed to be transported quickly to any location around the world. This allows us to respond very swiftly when an emergency repair is needed. We have been using this technology successfully for well over a decade and our teams have carried out many underwater shaft seal replacements in that period.
