A Hydrex diver-technician team recently performed an in-situ underwater stern tube seal repair on the mechanical seal of a 150-metre general cargo vessel in Lagos that had a rope stuck in its seal assembly from which oil was leaking.
The owner asked Hydrex to assist his vessel in Lagos because a similar operation had been previously performed on one of his other vessels.
As the ship was equipped with a mechanical seal assembly there was no need to mobilise a flexible mobdock as the repair could be performed in situ.
