Tanker Birgit Knutsen Suffered from Propeller Blade Damage

The four propeller blades had damages on the blade edges and MarineShaft received the four blades in our workshop in Hirtshals for repair.

Each bronze blade has a net weight of 4,600kg and has a height of over 2m.

After examining the blades, and with a class approved repair procedure in hand, we carried out the required crack tests before welding up the damages on the edges.

We used regular MIG Welding for the rebuild of the blades, followed by a final crack test and a complete polishing.

The sealing surfaces suffered from wear and we machined/milled all 4 blades in our milling machine. We have milling capacity for all sizes of blades/fixed propellers.DNV-GL was the involved classification society.

Repair time was 6 days
