Re-use, Rebuild, Reduce.


We see remanufacturing as the quickest step to make the maritime industry more sustainable. With a network of specialists, we bring knowledge and expertise together.


Scientific research

We have worked with researchers at the Delft University of Technology to produce a whitepaper that investigates the scientifically proven environmental and economic impact of remanufacturing. The findings are inspiring: compared to new-build ship parts, remanufactured components reduce the economic impact by 40-60%. And reduce the environmental impact by 60-80%. Read more about the whitepaper here.

Development & testing

In Q2 2023 we started a case study using two identical tunnel thrusters. We will be reconditioning one of these thrusters, bringing back its components to within the tolerances of the OEM. We will remanufacture the second thruster, bringing it back to its ‘as new’ state. This has never been done before. That is why we have invited Classification Society Bureau Veritas to observe the whole process and the techniques we are using. Our aim for the end of this case study is to have produced a set of class-approved remanufacturing requirements for a fully guaranteed product.

Increasing awareness & influencing policy

The core message of the Maritime Remanufacturing Network is common sense: the easiest way to be sustainable is to use your equipment for a longer period of time. However, public opinion and political will are crucial factors in achieving a more sustainable maritime industry. We aim to expand the knowledge of the benefits of remanufacturing to the widest public and political audience possible.

Rethinking the future

We have all seen the photos or read about the shipbreaking activities on Indian (Alang-Sosiya), Bangladeshi (Chattogram) and Pakistani (Gadani) beaches, where so-called ‘end of life’ ships are beached, to be dismantled with little regard to social or environmental conditions. Remanufacturing is just one way to prevent this situation; to RENEW products to comply with the latest rules and regulations, to REBUILD components to their ‘as new’ condition, and to REDUCE the environmental impact of industrial production.

Founder of the network

AEGIR-Marine is a Dutch company founded in 2000 that provides maintenance, repair services and spare parts for ship propulsion systems. A strong drive for innovation has resulted in the creation of this network with the aim of jointly accelerating the industry’s sustainability.

Partner introduction: CMT

Circular Maritime Technologies (CMT) was one of the first companies to join the Maritime Remanufacturing Network. We interviewed CMT’s founder and managing director Frank Geerdink to find out more about what this forward-thinking company does.

Remanufacturing is a key part of the circular economy model. It has the potential to be game changing in our industry as part of new business models.


Remanufacturing is the most rapid and feasible step that can be made towards a sustainable
