JBO company event | 2021

An unforgettable #company event is behind us. 🎉🥂

After a long Corona break, it was incredibly fun to meet everyone in person for the traditional #companyevent. Taking “3G” into account, we started with a harbor tour through Hamburg's port and landed with a lot of momentum in the Golf Lounge. Afterwards we celebrated with plenty of food and drink and a few rounds of mini golf. Simply overwhelming!

We are incredibly proud of this incredibly great team. Thank you all for this spirit! We missed these joint activities and are happy to be slowly returning to normal.

We are already looking forward to 2022 with you! #Companyevent #Teambuilding

Wind energy - digital building monitoring should make offshore plants more efficient | 2021

Jörss — Blunck — Ordemann GmbH (JBO) is partner with the BAM and further industry leaders to develop smart and software based inspection and maintenance strategies for offshore wind farms as one of the scopes within “DiMoWind-Inspect” research project.

The project, funded by the Federal Ministry for Economic Affairs and Energy, aims to predict and plan offshore repairs more cost-effectively. It is no secret that offshore wind energy plays a decisive role in Germany’s goal for climate neutrality, and the joint project aims to make periodic tests simpler and more efficient at the same time to support Germany’s climate neutrality goal.

JBO brings its diverse BIM (Building Information Modeling) experience from its onshore projects offshore to support the digitalization of inspection and maintenance for offshore wind farms.

Joint industry project launched to increase understanding of monopile buckling to extend lifetime of offshore wind assets | 2021

Looking forward to work with Bundesanstalt für Materialforschung und -prüfung and Technische Universität Berlin on the joined industry project VERBATIM aimed at investigating pile-tip buckling during the installation of large diameter monopiles.

The project is funded by the Bundesministerium für Wirtschaft und Energie and many major energy companies, administered by Projektträger Jülich, Forschungszentrum Jülich GmbH , and supported by The Carbon Trust. We are grateful for the trust placed in us by granting this research project with impact on the entire #offshorewind industry.

New Senior Leads Expert at JBO | 2021

As of May 2021, Dr.-Ing. Wojciech Popko will join JBO, where he will serve as a Senior Loads Expert focused on the global dynamic of OWTs, floating support structures, and sea ice loads topics. He will also strengthen our team with a profound understanding of verification and validation of aero-hydro-servo-elastic codes. Dr. Popko has more than ten years of experience in project management, technical execution, and the lead of international R&D and industrial projects with partners and clients across the EU, the USA, and Asia. He is also a recognized author of multiple peer-reviewed articles and conference publications in top international journals and conference proceedings. Before joining JBO, Dr. Popko worked as a researcher and a project manager at Fraunhofer IWES. In 2020 he obtained his doctorate from the Leibniz University Hannover.

New Senior geotechnical expert at JBO | 2021

From April 2021 onwards, JBO enlarges the scope of geotechnical design services. This covers the elaboration of geotechnical interpretative reports and the geotechnical foundation design for wind turbine generators and substations.

Kirill Alexander Schmoor, among other colleagues, will be responsible for this topic.

Kirill is experienced in the design of offshore foundation piles and suction buckets, including the analysis and interpretation of geotechnical soil profiles and laboratory tests and the application and evaluation of special design methods. He worked on more than 20 offshore projects dealing with offshore foundation piles' design and elaborating geotechnical interpretative reports and several research projects.
