(Cover) Three Dragon Geosciences vessels deployed at F4 wind farm for efficient operations.

SRE Group, a leading developer in Asia-Pacific offshore wind energy, entrusted Dragon Geosciences with the preliminary exploration of the Formosa 4 Offshore Wind Farm (F4). This project primarily focused on the geological assessment of the export cable corridor (ECC) and wind farm area, one of the most challenging tasks undertaken.

Dragon Geosciences integrated our internal Geophysical and Geotechnical teams and flexibly deployed our self-owned fleet to achieve precise, efficient, and incident-free project execution. The milestone tasks were successfully completedt, garnering high praise from SRE Group.

Project Overview

SRE Group is a leading developer in offshore wind power in the Asia-Pacific region, focusing on the development, construction, and operation of offshore wind farms. Formosa 4, which Dragon Geosciences conducted pre-surveys for, is one of the key offshore wind farms in continuous development by SRE Group. Under the experienced leadership of SRE Group, the pre-survey work was carried out meticulously. In addition to basic hydrological and geomorphological surveys, the focus was on conducting geological assessments of the shallow corridor from the intertidal zone to the onshore end, including evaluating geological conditions, geological hazard assessments, and fault identification, to ensure a comprehensive and thorough evaluation for wind farm development.

Operational Highlights (SOW)

  • Completed baseline hydrological and geomorphological surveys, including MBES, SSS, SBP, and MAG.
  • Conducted comprehensive geological assessments: hazard evaluation, fault identification, and soil condition analysis.
  • Achieved a technical milestone by completing UHRS in the 0–10m nearshore zone, obtaining critical shallow-water geological data.
  • Utilized Downhole CPT, Seabed CPT, and Vibrocore techniques, with investigation depths up to 100 meters.

Efficiency, Achievements, and Client Feedback

Dragon Geosciences deployed three proprietary vessels—Australis, Polaris, and Dragon Prince 2—for simultaneous operations, enabling the team to meet daily targets despite typhoon season challenges. The project was completed on schedule with zero safety incidents.

The client, SRE Group, praised the team’s professionalism and efficiency. The high-quality deliverables will support SRE’s detailed engineering planning and future development phases.
