Reinforcing Dutch expertise

Den Helder

The Dutch expertise center for the maintenance of underwater vessels is DMI, the Directie Materiële Instandhouding in the Navy Base in Den Helder. By co-locating the new submarine project here, thyssenkrupp Marine Systems will further develop the already indispensable technical and industrial expertise in the field of submarine maintenance, by transfer of knowledge and technology.

Triple Helix & thyssenkrupp Marine Systems - CSSI

The merger of the Dutch Triple Helix and thyssenkrupp Marine Systems will result in a Centre for Submarine Service and Innovation (CSSI) at the Navy Base in Den Helder. The CSSI will also benefit from the operational and technical expertise of both the Royal Netherlands Navy and thyssenkrupp Marine Systems, thereby offering even more opportunities for naval development.

The CSSI will support regional development and result in the creation of approximately 500 direct and 1,500 indirect jobs in the province of North-Holland for a period of about 30 years. thyssenkrupp Marine Systems is prepared to invest in this center for service and maintenance of a considerable number of similar submarines. In this way, we can create economies of scale and ensure long-term maintenance and innovation with a dedicated workforce.

Sharing knowledge

In addition to investing in the CSSI, we are also prepared to share our key technologies, such as Air-Independent Propulsion (AIP), stealth technology, and handling of non-magnetic steel with Dutch partners. By also involving knowledge institutes such as TNO, Marin and NLR, our goal is to explore all possible synergies with the Dutch Triple Helix and its submarine knowledge. DMI will also be involved in sharing this knowledge.

How would it work?

With the support of thyssenkrupp Marine Systems, the new submarines will be outfitted in the Netherlands. Training of DMI staff, as well as outfitting and related test and trials lays a solid foundation for future maintenance of these submarines during their entire lifespan. Through the use of a public-private partnership, thyssenkrupp Marine Systems and DMI will join forces to successfully complete the project, including significant opportunities for transfer of technology and knowledge as well as skilled job creation.
