Rainbowco Expands Offshore Wind Foundation Capabilities Amid Growing Global Demand

## Rainbowco Expands Offshore Wind Foundation Capabilities Amid Growing Global Demand Nantong Rainbow Offshore & Engineering Equipment Co., Ltd. (ROC), a wholly owned subsidiary of Jiangsu Rainbow Heavy Industries Co., Ltd. (RHI) (SZSE: 002483), is expanding its offshore wind foundation manufacturing capabilities, the company announced on 7 July 2026. According to a PR Newswire release, ROC is leveraging its proven global delivery experience to consolidate its position as a key supplier in the offshore wind equipment sector. The move reflects broader momentum across the offshore wind supply chain, where manufacturers are scaling production capacity to keep pace with ambitious renewable energy targets in Europe, Asia-Pacific, and North America. ### Strategic Positioning in a Competitive Market ROC's expansion underscores the increasingly central role that Chinese heavy industry manufacturers are playing in the global offshore wind supply chain. Foundation structures — including monopiles, jackets, and transition pieces — represent some of the most capital- and logistics-intensive components in offshore wind development, requiring specialist fabrication facilities and heavy-lift marine logistics capabilities. By citing 'proven global delivery experience,' Rainbowco signals its intent to compete not only on manufacturing cost but also on reliability and international project execution — factors that have become critical differentiators as developers push into deeper waters and more complex installation environments. ### Industry Context The offshore wind sector continues to attract significant investment globally, with foundation supply widely identified as a potential bottleneck to project delivery timelines. Expanded fabrication capacity from established manufacturers such as ROC could help alleviate supply constraints that have, in some markets, contributed to project delays and cost overruns. Parent company RHI is listed on the Shenzhen Stock Exchange, and its offshore and engineering equipment subsidiary has built a track record across multiple international markets. The latest capacity expansion is expected to further enhance ROC's ability to fulfil large-volume foundation contracts for projects across different regulatory and environmental jurisdictions. As the energy transition accelerates, the competitive landscape for offshore wind foundation supply is intensifying, with manufacturers in China, Europe, and Southeast Asia all investing in new facilities and production technologies. ROC's announcement positions Rainbowco as an active participant in that global race to scale. *Source: PR Newswire*
