The ship had suffered an oil leak and no drydock was available close by.
The divers replaced the damaged seals underwater using one of the company’s flexible mobdocks. This saved the owner an expensive and time-consuming trip to a far away drydock.
Once the operation was confirmed, all preparations were handled swiftly and the lightweight equipment was mobilised almost immediately. The team was on-site and ready to start the seal replacement when the vessel arrived at Algeciras.
The operation began with a thorough underwater inspection of the stern tube seal assembly. This revealed that a rope had become entangled around the assembly. The divers removed the rope but unfortunately it had already damaged the seals and caused an oil leak.
The team then removed the rope guard and installed the flexible mobdock. This allowed them to work in dry conditions.
During the operation divers removed the three damaged seals and replaced them with new ones.
Working together with the OEM allowed Hydrex to provide the customer with original spare parts, which guarantees the best quality material, the company claimed.
A technician of the seal manufacturer was also present during the operation.
