About MarineShaft

Our core capability 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.

MarineShaft delivers complete repair and reconditioning of propulsion and rudder equipment, both on-site and as full overhaul projects. We perform welding, machining, alignment, and 3D scanning in accordance with certified procedures and proven repair methods, supported by high-capacity workshop facilities including lathe capacity up to 27 meters.

We also manufacture new propeller shafts, rudder stocks, and critical components with short lead times, supported by a large stock of class-approved materials.

With global mobilization and dedicated service teams, we deliver technically precise repair solutions wherever your vessel is located. We can manage the full repair scope as a single point of responsibility, ensuring efficient execution and minimal downtime.

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.
