Project for Researching Corrosion Inside Monopiles Started | 2023
Corrosion inside monopiles is a widespread phenomenon in offshore wind farms, but the knowledge about its origin and impact on the life time is very limited. JBO is investigating the phenomenon in an interdisciplinary collaboration with the Kiel University of Applied Sciences, the GEOMAR Helmholtz Center for Ocean Research Kiel and Krebs Korrosionsschutz GmbH. The project “Microbial Fe corrosion and possible corrosion protection measures in the monopile of offshore wind turbines (MiCorFe)” is funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) over 3 years.

AGILE DESIGN - JOINT SHM AND FOUNDATION DETAILED DESIGN APPROACH | 2023
JBO & WÖLFEL Wind Systems
The SHM provider Wölfel and JBO have united their expertise and developed the Agile Design approach. Based on the SHM system output JBO will bring in their deep knowledge on offshore wind structural foundation design and dynamics. This allows for a detailed reassessment of the existing structures based on as-built information and measurements.
Please see also the discription of the innovative Agile Design approach on our partners website: https://www.woelfel.de/shmfoundation-agile-design.html
Agile Design Model
An Agile Design model will be setup and parametrized by JBO that reflects the real physical foundation. The model will be used to simulate and predict the performance of the physical structure on a regular basis.
Motivation
The offshore wind sector is pushing the limits since years. JBO desires to create the awareness that OWT are much more dynamically driven with size and hence highly sensitive to lifetime assumptions.
Continuous SHM combined with deep foundation design expertise is the key to reduce these uncertainties and risks. Furthermore, lifetime extension is seen as major contribution to improve the sustainability in offshore wind design.
JBO Role & Capabilities
JBO will analyse the design and as-built documentation package. Environmental conditions (wind, wave, ice, seismic, etc.) are updated and a structural model will be set up. A detailed geotechnical re-analysis based on 3D-FE methods allows to accurately reflect the soil-pile interaction. By application of the agile model a lifetime assessment based on SHM data predicts the real damage.
Sharp Interfaces
JBO and Wölfel developed a clear design model process that defines the workflow of the Agile Model setup.
Outcome
The added value of the Agile Design process is a real time assessment of each structure’s lifetime, and a WTG specific traffic light classification of the design relevant KPI’s of your structures. It will provide you the real asset value for each specific turbine and reduces the operators risk by having all relevant key parameter monitored.
What’s next
Feel free to contact JBO to get further information on the agile design process. We will further elaborate on the importance of joint SHM and detailed design insights and demonstrate how this will add value to your project.

Lots of space for our "little people" | 2021
Jörss-Blunck-Ordemann GmbH and the Acollage architecture office are pleased that the AWO Kita building project is about to be completed. Jörss-Blunck-Ordemann GmbH has taken over the service phases 1–5 of the structural engineering. Despite the large spans, it is Jörss-Blunck-Ordemann
GmbH succeeded in developing an economical supporting structure.
Due to the cost-effective construction, the AWO is able to implement further charitable projects.

We give full power! | 2021
JBO pool vehicle fleet now with electric car.
With the change of location from Isestraße to Kaiser-Wilhelm-Straße, we have added an environmentally friendly BMW I3 to our pool vehicle fleet.
Because we have many power connections for charging the battery due to the city location and the car is perfect, especially for short trips in and around Hamburg, the small electric speedster is very popular with our employees.

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
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.
