Antwerp-based underwater repair and maintenance specialist, Hydrex, has carried out a rudder repair on a 170-meter container vessel during the ship’s scheduled maintenance stop in Rotterdam.
Hidrex divers team, with one of its dive support workboats, installed a doubler plate over the cavitated area of the rudder after the damage has been detected during an earlier inspection carried out in Algeciras.
The diver/technician team worked in shifts and finished the operation in 24 hours.
The preliminary inspection in Algeciras, combined with the drawings of the rudder, allowed for the ahead-of-time preparation of the doubler plate.
After the plate was fitted and secured, diver/welders then installed anodes on both sides of the rudder for further protection.
