Rudder Repairs and Modifications While Afloat

5 Oceans Diving specializes in underwater rudder repairs, inspections and modifications for vessels worldwide. Whether your vessel has suffered impact damage, cavitation erosion, flooding or structural defects, our experienced divers, welders and technicians can perform repairs while the vessel remains afloat, minimizing operational downtime and avoiding costly dry dock periods.

Permanent Rudder Repairs Using Cofferdams and Hyperbaric Habitats

5 Oceans Diving has developed specialized cofferdam and habitat systems that allow permanent rudder repairs to be carried out in a dry and controlled environment below the waterline.
