Since 2014, we have been offering propeller, hub and blades refurbishment services. We rebuild copper alloy (CU3 bronze) propellers by weld overlay, welding, straightening and machining.

We hold the following DNV certificates and licenses:

  • License to weld coloured materials
    • 131 and 141 method,
  • International engineer certificate and welding inspector certificate,
  • License to carry out nondestructive testing, i.e.
    • PT – penetrant testing,
    • MT – magnetic particle testing,
    • UT – ultrasonic testing.

We offer propeller repair technology prepared in accordance with the classification societies (DNV) and adequate repair aimed at restoring the nominal shape and strength of the propeller blade. Besides, we perform machining of the blade sealing surface.
