We build for humans


We're convinced that even with decades of experience in the field of planning, construction and operation of ports and terminals, the development and implementation of supply chains and the planning and realisation of real estate projects, it's vital to keep evolving. 

We've made our share of mistakes in our decades of professional activities, but we've always tried to see mistakes as opportunities, to analyse and understand their causes to avoid them in the future by adapting our systems.


For example, over the last 20 years, we've developed an AI-based predictive maintenance system that reflects all our experience in FM. The analyses derived from this have been incorporated into our standardised service descriptions.

We are and intend to stay a small team of experienced, dedicated and excellent professionals.

This way we can ensure that a full flow of information between our clients, the partners involved and us.

We consider ourselves universally thinking experts with a neutral focus on the respective, individual issues of our customers. 

At any time, we can call on the staff of more than 110 affiliated companies, who support us with their specialised knowledge from their fields. 

We stand by our clients until the project is fully completed and always act in their interests. 

We involve them in the respective decision-making processes – in the end, it is and remains their project.

Thomas Schlipköther leaves big footprints. He played a decisive and formative role in duisport's development into the largest inland port in the world. We thank him for that!

Markus Bangen

CEO of Duisburger Hafen AG (duisport)

I like to  express for sure a deep proudness to have taken part with you  and your very special team to a very ambitious project, linking very tightly, human factors with productive capacity and costs. Factors that seems to be in contrast with each other. 


Here comes the absolute need “not to stand in front of the answers” of the people directly involved before developing our proposals.

Just following the the operational standards already settled would have probably prevent from taking the right direction.


It took a great clear courage and each one of us has committed all his skills and passion to go as a group in one common direction.


I would like to thank all of you with deep gratitude

Ever since me and my team started the long and extremely difficult journey of setting up a container terminal in Galati (Romania), Prof. Thomas Schlipkoether, whom I proudly like to name my good friend, believed in this project’s feasibility and encouraged us to keep the work going and never give up.

His extensive knowledge and most precious experience in the construction and logistics industries are our guarantee that with his support the further steps we shall take will shortly lead us to achieving our goal.

Thank you my dear friend, and I wish you nothing but good health and big success in this new pledge you’re taking.
