China: CIC Changxing Shipyard Completes MV Stella Eagle Repair Project

But when the ship went into the drydock, it was found that the rudder pin bearing was damaged, the pin sleeve was loosened, the pin hole was seriously rusted, and the propeller cap was missing.
Facing such a issue, CIC Changxing shipyard took quick response of making reasonable arrangements for blasting & dry-docking repair and used the interval of blasting to remove the rudder pin into the workshop. The workers quickly measured the size of the rudder pin holes, handed over to the ship side, and arranged to prepare bore hole. When the working staff calibrated the device, they also found that rudder blade and rudder hole axis could not match. The yard’s workers worked overnight, dismantled & assembled the device several times, measure the offset of rudder blade at different angles. With the joint efforts from various departments of the shipyard, the pin hole of rudder was born in the shortest time and the rudder pin repair work was also completed earlier than expected.
