Mr Ordemann completed his civil engineering studies with a specialization in structural engineering at the TU Braunschweig in 1980 with a diploma. He then worked for the construction company Dyckerhoff + Widmann AG in the technical office, in the calculation department and construction management until 1987. Then Mr Ordemann moved to the engineering office Jörss + Blunck and became a partner in 1990. In 1993, Mr Ordemann was approved as an inspection engineer in concrete and steel construction. In 1995 he was then approved as an inspection engineer for structural and bridge construction at the Federal Railway Authority. In 2001, he was appointed state-approved expert for structural testing tasks. Mr Ordemann works voluntarily in the Chamber of Engineers and the Association of Inspection Engineers for Structural Analysis as a member of the technical committee of Lower Saxony, Bremen and Hamburg states and the technical coordination committee of the federal association.
Dr. Falk Lüddecke
Managing partner of Jörss - Blunck - Ordemann GmbH; approved as structural engineering inspector; active in civil engineering planning since 2002.
Full vita
Dr Lüddecke completed his studies at the TU Dresden at the Faculty of Civil Engineering with a diploma. During the subsequent doctorate in upgrading existing steel bridges, Dr Lüddecke gained further knowledge in fracture mechanics and the fatigue behaviour of steel components. In addition, he completed his certificate as a welding engineer. During the doctoral period, which was completed in 2006, and afterwards, Dr Lüddecke gained further knowledge in engineering construction. From 2006 to 2009, Dr Lüddecke joined a well-known engineering office in Berlin and also worked at the BAM (Federal Institute for Materials Research and Testing) for the German authorities as reviewer of the structural design of various offshore wind farms submitted for approval.
In 2009, Dr Lüddecke moved to Bremerhaven to the engineering office tkb. GmbH, which is active in the planning of substructures for offshore wind turbines. Here, Dr Lüddecke built up the structural department and became managing director of the tkb GmbH in 2010.
In the course of further development, Dr Lüddecke joined Jörss - Blunck - Ordemann as managing partner in 2014. In 2016, Dr Lüddecke was appointed inspection engineer for structural engineering (concrete and steel construction). Dr Lüddecke is involved in various working groups for the German offshore wind standard DIN 18088 and in updating existing standards of the German authorities.
Frank Heitmann
After completing his technical apprenticeship, Mr Heitmann began studying civil engineering and graduated in 2007. In parallel to his first job in a Berlin engineering office, he took a further postgraduate course to deepen his knowledge at the HTW Dresden and graduated in 2010.

Walid Al Otaibi
Mr Al Otaibi, born in Kuwait, started his studies in civil engineering in structural engineering in 2005 at the University of Kassel. During various stays abroad, he was able to gain his first experience in the planning and construction of large engineering structures. He was involved in constructing several hundred-meter-high skyscrapers in various megacities on the Persian Gulf.
Full vita
Since entering the offshore industry in 2011, he has been involved in designing, dimensioning and constructing substructures in the offshore wind sector. In the meantime, his field of activity has extended to Southeast Asia. With his multicultural background, he is considered a natural communication talent. This means that he acts as a link to our customers on an international level. He joined Jörss-Blunck-Ordemann GmbH in 2014. Meanwhile, he occupies the role of Director Offshore and in 2018, he received individual power of attorney for our company. In 2024, he was appointed as the Managing Director of our company.
Michael Schwedler
Dr-Ing. Michael Schwedler brings a wealth of expertise and experience to our team at JBO. With his apprenticeship at Berliner Wasserbetriebe from 1999 to 2002 and his subsequent work as a civil structural engineer at KLW Ingenieure in Berlin, Dr. Schwedler laid a solid foundation for his practical work as a structural engineer.
Full vita
His passion for innovation led him to the renowned Bauhaus-Universität Weimar in 2009, where he worked as a research assistant on the development of finite element methods. After completing his PhD in 2016, he started working for JBO and quickly established himself as a senior structural engineer. His leadership qualities and technical ingenuity were demonstrated time and again in his daily work. Since January 2022, he is leading the Offshore Structural Design department with great commitment and clear goals. With him as head of the department, it has grown steadily and continues to set new standards in the industry. Since 2024, he also carries responsibility for JBO as an authorized representative. We are convinced that Dr. Schwedler's commitment to excellence and his forward-thinking approach will continue to take our company to new heights.
