About MarineShaft

Our core business is cold straightening of propeller shafts and rudder stocks – a class-approved repair method recognized by all major classification societies as permanent and equivalent to new. But we offer much more.

From our facilities in Denmark, MarineShaft delivers complete in-house and on-site repair solutions for all types of propeller and rudder equipment. We handle everything from welding, machining, and alignment to complete overhaul and 3D scanning – always with certified procedures and fast mobilization.

With a large stock of class-approved materials and full machining capabilities, we also manufacture new propeller shafts, rudder stocks, and other critical components with short delivery times.

Wherever your vessel is, we are ready to deliver certified solutions – fast, precise, and reliable.

We prioritize repair whenever possible, extending the service life of rudders, propellers, and other critical equipment. 

Using proven methods such as cold straightening, laser cladding, and mobile machining, our approach ensures cost-effective repairs without unnecessary replacements, thereby reducing both time and expense for our clients. This approach also reduces resource consumption and minimizes CO2 emissions without compromising performance or reliability.

Certified according to ISO 9001:2015 and fully compliant with Danish regulations, MarineShaft maintains strict quality standards while continuously investing in equipment and skills to meet the demanding requirements of marine repair services worldwide.
