The company has written new, class approved, welding procedures specifically for the repair of cavitation damages and new tip material (CU3 and CU4) enabling class-approved propeller repairs to be carried out in-situ without removing the propeller from the shaft. At the same time, MPR has invested in welding equipment, specially developed for welding on a vertical plain.

It’s also the first company to be certified by a classification society for PA, PB, PC and PF welding of Ni-Al-Bronze propellers (CU3 and CU4). In addition, MPR is the only company certified for welding in the PF positions of propellers.


All MPR welders are highly-experienced and class-certified to carry out these challenging repairs.
