Doubler Plate Repair in Bulk Carrier After Collision

A 190-meter bulker suffered severe collision damage in Lagos, Nigeria. A large hole in the hull plating prevented the ship from sailing at full speed. The classification society also demanded that the vessel go to drydock immediately unless an on-site solution was found. Hydrex therefore sent a diver/technician team to the vessel’s location to carry out an emergency doubler plate repair at anchorage.
