Hydrex diver/technician team recently carried out an underwater stern tube seal repair on a tanker berthed in Antwerp.

The ship was suffering from an oil leak, making an on-site repair necessary.

Using a Hydrex flexible mobdock the team was able to carry out the entire operation on-site and underwater.

The operation started with underwater inspection of the stern tube seal assembly. It was revealed that a rope and a fishing net were entangled around it. Both were removed by Hydrex divers and the flexible mobdock was installed to allow for work in dry conditions.

During the operation the divers removed the three damaged seals and replaced them with new ones.
