In addition to deflection, the rudder stock had also suffered damages to the lower rudder cone as well as the top. The damages were machined, welded up, heat treated and re-machined. Two new stainless steel liners, supplied by Becker Marine System, were machined and fitted to the rudder stock, which was also painted between the liners. With a custom-made tool, we machined the rudder cone.
As the steering machine foundation was displaced due to the incident, the existing reamer holes had to be re-machined, and this MarineShaft carried out with portable equipment. The 6 new bolts were manufactured by MarineShaft.
Kongsberg and Orskov Yard took care of the re-installation. Everything went as planned due to a good planning and co-operation.
November 18th M/V Mary Arctica docked out and is right now at quay in Aalborg at Royal Arctic Lines terminal getting ready for the next charter to the South Pole.
We co-operate with other Danish Shipyards as well, and as for these 2 jobs, we are always proud to participate in a repair.
