Ramboll has been contracted by CSBC DEME Wind Engineering (CDWE) to deliver the full jacket foundation design for the Hai Long Offshore Wind Project.

Ramboll will perform the FEED and detailed design of the jacket structures supporting the project's 14 MW SG 14-222 DD offshore wind turbines. The jacket foundations will be installed at water depths ranging between 43 m and 56 m, adding complex challenges to the design and engineering aspects. Situated in-between tropics, Taiwan’s offshore waters are exposed to extreme natural forces such as earthquakes, sand waves, and soil liquefaction. This requires innovative thinking and flexibility in terms of foundation techniques and installation.

“Even though it’s not our first project in Taiwan we are very honoured that CDWE has chosen us to deliver the most-cost effective jacket foundation design. We are also very glad for the opportunity to continue our journey on the Asian market and support Taiwan’s growing agenda towards more renewable sources”, said Santiago Paredes-Pinzón, Head of Department at Ramboll.


“Ramboll is a respected company with solid offshore wind experience worldwide and we believe their knowledge and expertise will have a positive influence on the design of Hai Long’s foundations, even though the natural environment in the strait waters is challenging” commented Marco Kanaar CDWE Project Director.


“We are dealing with challenging site conditions, but our previous experience from Taiwan and worldwide has helped us enormously in understanding how these natural forces work against the structures. Basically, it comes down to finding a fine balance between innovation and looking back at what has already been done. I am confident that with this vision in mind we will be able to find the best solution for our client”, added Santiago Paredes-Pinzón.


Ramboll has appointed local consulting firm T.Y. LIN to ensure the design is compliant with local standards and regulations.


“When designing offshore wind foundations, it’s not only about the challenges caused by the environmental conditions, but also about being compliant. We always seek to learn and understand the local standards and regulations, which is why we decided to collaborate with a local company to help us strengthen our knowledge in this area. We look forward to have T.Y. LIN onboard with us during the project”, Santiago Paredes-Pinzón concludes.


The Hai Long offshore wind undertaking consists of three separate projects:
Hai Long 2A (300 MW), Hai Long 2B (232 MW) and Hai Long 3 (512 MW). Recently, the 300 MW Hai Long 2A’s Industrial Relevance Proposal was conditionally approved subject to certain conditions to be fulfilled by Hai Long as agreed with the Taiwanese authorities.

Hai Long is Ramboll’s fourth large scale detailed design project in Taiwan after, Changfang and Xidao (589 MW), and Zhong Neng (300 MW) where the Danish engineering company has also been responsible for delivering the full jacket foundation designs.
