Class-approved cold straightening

MarineShaft is specialized in class-approved cold straightening of all types of shafts: Propeller shafts, tail shafts, intermediate shafts, ram shafts and rudder stocks. With our purpose-built equipment which can press with up to 6,000 tonnes, and many years of experience, we are able to straighten shafts - from 20 mm to more than 1,500 mm in diameter.

MarineShaft has the approval from all the leading classification societies for carrying out cold straightening of propeller shafts and rudder stocks. Our alignment service was first approved by Bureau Veritas in 1972. We straighten shafts without any heating and our unique cold straightening technique is fully approved. Our repair is considered to be a permanent repair without any conditions.

All work is done in close co-operation with the classification societies, and a certificate is issued on each individual repair.

We always have capacity for urgent repairs. Our many years of experience qualifies us to make the right decisions fast. Another strength is our short decision paths - this enables us to act immediately.

Straightening shafts is much faster than manufacturing new shafts. Many jobs can be completed within 24-48 hours from arrival at our workshop. When necessary we work round the clock to ensure our customer the best delivery time.

Straightening is a more economical solution than having new shafts manufactured. MarineShaft straightens propeller shafts and rudder stocks from all over the world. No matter where in the world the propeller/rudder damage occurs, a straightening is often a profitable solution.
