Goltens solves complex rudder stock problem for Ben Kien shipyard

M/V 9200T-03 - The rudder stock rectification

M.V 9200T -03 is a new build vessel in Ben Kien shipyard- Hai Phong in the North of Vietnam. Prior to installation of the rudder stock on the vessel, it was found that some heavy corrosion had taken place on the shaft surface. The ship owner required that the shaft be returned to a new condition prior to installation and that the procedure had to be approved by BV class.

The shipyard was unable to find a local repair company to handle this work as a complete repair package with an acceptable procedure. Goltens Vietnam based in Vung Tau in the South of Vietnam was able to propose a procedure that was accepted by BV Class. This involved removal of defective material, heating the shaft using Goltens’ annealing equipment, rebuilding the defective area and machining it back to original size.
