History

Nature is our guide in efficient design. Like our company name would suggest, the inventor of our composite joint Marko Pavlovic assistant professor Steel and Composite Structures at TU Delft, got inspired by trees. Near his hometown the local community saved a 300 years old tree by supporting it with steel tubulars. Over time it grew over and around these steel tubulars, creating a structural connection.

A tree reacts to the loads it is subjected to, it will grow additional fibres only in the locations where they are needed, this forms the essence of our joint technology to shape it in an optimal manner. With the first prototype being built in 2017 at Versteden B.V., a close collaboration has followed with over 90 tests executed at TU Delft to perfect this technique. With success after success, Tree Composites was founded in 2020 with the aim to get this technology to the market. At the end of 2020 the certification body Det Norske Veritas provided the statement of feasibility for this technology.

Peter Bogers

Commercial director & co-founder

Bachelor’s degree in Mechanical Engineering at the HTS in Breda. Since 1995 he is active in the FRP piping business and in 2009 he became the commercial director of Versteden B.v.. His expertise and experience in the manufacturing of fibre reinforced polymers is invaluable for the company and his role is to lead the development of the manufacturing of the wrapped composite joints.

Tim Kapteijn

Structural engineer

Tim graduated from the TU Delft on the feasibility of an uniaxial TC-joint in a monopile breasting dolphin. Within Tree Composites Tim focusses on pilot projects to demonstrate the technology and on certification of the TC-joint. In the WrapNode-I research project Tim is responsible for the integration of the TC-joints in the steel jacket structure and the project management of the jacket design.

 

 

 

Mees Wolters

Composite Engineer

Graduated from TU Delft in December 2020 at which he developed a forming analysis to create mesoscale finite element models of complex composite structures. He obtained his bachelor’s degree at the Hogeschool Arnhem and Nijmegen, graduating on lateral load resisting frames for offshore skids. During his master studies, Mees worked part-time at SPIE Nederland where he developed analytical models for high-voltage lattice masts and substations. Within Tree Composites he focusses on the composite design of the TC-joint, production process and cost determination.

Vasilis Mylonopoulos

Composite Quality Engineer

Graduated from TU Delft on bi-material interface properties of composite to steel bonds. Before coming to the Netherlands he studied civil engineering at the University of Patras in Greece. Working as a trainee in Milan he gained experience with finite element modelling of large commercial and public projects. Within Tree Composites he focusses on the development of automated manufacturing of the TC-joint.
