Sustainability and environmental awareness and responsibility are highly prioritized at MarineShaft A/S.

With respect to these, we always strive to repair rudder and propeller equipment when possible, instead of manufacturing new parts. By repairing, the service life of vital marine parts is prolonged, thus saving the environment from large CO2 emissions.
Calculations show that new manufacturing emits 1 kg of CO2 for every kg. steel used. In the period 2016-2020, MarineShaft repaired 1,079,659 kg. of steel saving well over 1 million kg CO2 emission during that period of 5 years.

MarineShaft A/S is ISO 9001:2015 certified and fully compliant with the Danish law and regulations.

Machine capacity

We have the experience and the equipment that enable us to solve any problem our customer may have with the propeller equipment or rudder arrangement. We are able to handle even very large dimensions.

With our purpose-built equipment that can press with up to 6,000 tonnes, and many years of experience, we are able to straighten shafts of all sizes - from 20 mm to more than 1,500 mm in diameter.
