IOG Wind has obtained a multiyear operations and maintenance (O&M) contract for the balance of plant of the Hai Long Offshore Wind Project in Taiwan. 

This represents IOG Wind's second long-term O&M contract since its founding in 2018, and the first since it became a wholly owned subsidiary of International Ocean Group (IOG) in 2023. 

The Hai Long project is located 45-70km off the coast of Changhua County, at depths ranging from 35m to 60m.

It includes Hai Long 2 and Hai Long 3 and comprises a total of 73 turbines. 

The contract encompasses the inspection of newly installed offshore substations, as well as the inspection, maintenance, and troubleshooting of transition pieces, subsea foundations, and various other structural components. 

Additional tasks such as subsea cable inspections and onshore substation operations are scheduled to begin shortly. 

The Hai Long project is set to commence commercial operations by late 2026, providing more than 1GW of installed capacity. 

Hai Long project CEO and project director Tim Kittelhake said: “As the largest offshore wind project in APAC [Asia-Pacific], we have signed over 100 contracts with Taiwanese suppliers during [the] construction phase, with a total value exceeding $4bn.  

“Now, as we move toward grid connection and prepare to enter the O&M phase, we are confident that IOG Wind’s strong technical expertise and mature management capabilities will ensure the stable, safe, and efficient operation of the Hai Long wind farm after commercial operation, while also supporting the long-term development of Taiwan’s offshore wind supply chain.” 
 
IOG chair Vincent Tsai said: “We are truly honoured to have secured this significant contract with the Hai Long project. Since its establishment, IOG Wind has consistently expanded its service scope and strengthened local execution capabilities, supported by a professional team of sales, engineers and resilient project management expertise. 

“Following IOG’s full acquisition of CWind Taiwan (IOG Wind was formerly known as CWind Taiwan), we are proud that our professional strengths remain consistently acknowledged by clients.

"Through innovative and optimised solutions, and by further advancing Taiwan’s local supply chain, IOG Wind will support Hai Long in maximising performance and revenue throughout its life cycle, while contributing to Taiwan’s sustainable energy future.” 

This August, Century Wind Power delivered 21 three-legged jacket foundations for the 1GW Hai Long Offshore Wind Project.
