CDWE Completes Installation of 73 Jacket Foundations for Hai Long Offshore Wind Project　Delivering 1 GW Subsea Foundations Ahead of Schedule

CSBC-DEME Wind Engineering Co., Ltd. (CDWE) and the Green Jade project team joined project owners at Port of Taipei to commemorate the completion of the final batch of jacket foundations.

CSBC Corporation, Taiwan (CSBC) announced on Aug 20th that its subsidiary, CSBC-DEME Wind Engineering Co., Ltd. (CDWE), has successfully completed the installation of jacket foundations for the Hai Long Offshore Wind Project (hereinafter referred to as the Hai Long Project). Following the successful completion of 219 monopile installations in June in 2025, all 73 jacket foundations have now been fully installed ahead of schedule!

CDWE deployed its self-owned installation vessel Green Jade as the main construction vessel for this operation. This milestone highlights both Taiwan's marine engineering capabilities and the collaborative achievements of the Hai Long project team.

The Hai Long Project is the largest offshore wind farm contract CDWE has undertaken to date. Its subsea foundation structures are the largest in volume and weight among Taiwan's current wind farms. Located in the challenging waters of the Taiwan Strait, the project required careful consideration of weather windows, sea conditions, and typhoon risks. Through rigorous project management, seamless team coordination, and a safety-first approach, CDWE effectively managed risks, overcame multiple challenges, and ensured the project was delivered on time and to specification.

With a total installed capacity of over 1 GW, the Hai Long Project is one of Taiwan's largest offshore wind developments. In 2022, CDWE signed the contract for a full range of marine engineering services, including monopiles, jacket foundations, offshore substations, and wind turbine transportation and installation. Offshore installation works officially commenced in 2024. Using its flagship vessel Green Jade, CDWE has now completed nearly 1.5 GW of offshore wind installation capacity in the Taiwan Strait—including Hai Long—demonstrating local marine construction capabilities, fostering maritime engineering talent with international experience, and advancing Taiwan's offshore engineering technology to new heights.

CSBC-DEME Wind Engineering Co., Ltd. (CDWE) successfully delivered the installation of jacket foundations for the Hai Long Offshore Wind Project ahead of schedule.

Tim Kittelhake, CEO and Project Director of the Hai Long Project, stated: "The jacket foundation installation work was carried out with impressive efficiency, with a record of three foundations completed within just two days. The exceptional capabilities of Green Jade, combined with the Hai Long team's outstanding planning, coordination, and execution, enabled the completion of all 73 jackets ahead of schedule. This milestone underscores the steady progress of the Hai Long Project and strengthens confidence in achieving the grid connection target on time."

CDWE Chairman Robert Tseng said: "The completion of jacket foundation installation today is another testament to the spirit of teamwork. For CDWE and Green Jade, this marks not only another milestone but also clear evidence that Taiwan's marine engineering strength has advanced significantly. From manpower and infrastructure to supply chain management and technical innovation, this achievement lays a strong foundation for the continued growth of the Taiwan Marine Team."
