Offshore Wind Progress: RWE Launches Vanguard West Survey While Ørsted Completes Taiwan Cable Installation

## Offshore Wind Developers Mark Key Project Milestones The offshore wind sector is registering notable progress on two fronts this week, with RWE and Ørsted each advancing large-scale projects at different stages of development. ### RWE Begins Pre-Installation Survey at Vanguard West RWE is set to commence a pre-installation survey campaign at its Vanguard West offshore wind farm site, according to Offshore Energy. The survey marks an important preparatory step for the 1.4 GW project, which ranks among the more significant capacity additions in the offshore wind pipeline. Pre-installation surveys are a critical phase in offshore wind development, providing developers with detailed seabed, environmental, and geotechnical data necessary to finalise foundation and cable route designs before construction vessels are mobilised. The commencement of this work signals that Vanguard West is advancing through its development lifecycle toward the installation phase. Vanguard West forms part of RWE's broader offshore wind growth strategy as the German energy major continues to expand its renewables portfolio across European waters. ### Ørsted Completes Inter-Array Cable Work at Greater Changhua Meanwhile, Ørsted has reached a significant construction milestone at its Greater Changhua 2b and 4 offshore wind farm in Taiwan, with all inter-array cables now installed and energised, Offshore Energy reports. The combined project carries a total capacity of 920 MW. The completion of inter-array cable installation and energisation is a pivotal step toward full commercial operations, as these cables form the electrical backbone connecting individual wind turbines to the offshore substation. With this work concluded, the project moves closer to delivering power to Taiwan's grid. Greater Changhua 2b and 4 represents a cornerstone of Ørsted's Asia-Pacific strategy and contributes to Taiwan's ambitious renewable energy targets as the island nation seeks to diversify its energy mix and reduce dependence on fossil fuels. ### Industry Outlook Together, these developments reflect the continued momentum across the global offshore wind industry, with developers progressing projects at scale across European and Asian markets. The sector faces ongoing challenges around supply chain capacity and installation vessel availability, making disciplined project sequencing — as demonstrated by both RWE and Ørsted — increasingly important to maintaining delivery timelines.
