Offshore Wind Sector Gains Momentum as Rainbowco Strengthens Foundation Manufacturing Capabilities

## Rainbowco Reinforces Offshore Wind Foundation Manufacturing Position Nantong Rainbow Offshore & Engineering Equipment Co., Ltd. (ROC), a wholly owned subsidiary of Rainbowco Jiangsu Rainbow Heavy Industries Co., Ltd. (RHI, SZSE: 002483), is continuing to strengthen its standing in the offshore wind foundation equipment manufacturing sector, according to a company announcement dated 7 July 2026. The Qidong, China-based firm is building on its track record of large-scale global deliveries to consolidate its capabilities in the design and fabrication of foundations for offshore wind turbines — a critical component of the rapidly expanding renewable energy supply chain. Offshore wind foundation manufacturing has emerged as a strategically significant segment of the maritime and offshore engineering industry, with developers worldwide accelerating project pipelines to meet national and regional clean energy targets. Monopiles, jackets, and transition pieces represent some of the most logistically complex and capital-intensive elements of offshore wind development, placing specialist fabricators such as ROC at the centre of the energy transition. ROC's parent company, RHI, is a publicly listed heavy industries group with established credentials across offshore and marine engineering. The subsidiary's focus on scaling delivery capacity signals growing confidence in sustained demand from both Asian and international offshore wind markets. While specific contract details were not disclosed in the announcement, the company's emphasis on 'proven global delivery experience' suggests an active international order book and a strategic intent to compete for projects beyond the Chinese domestic market — a trend increasingly common among Chinese offshore fabricators as European and Asia-Pacific developers seek cost-competitive supply chain partners. The offshore wind foundation sector is expected to remain a high-growth area through the late 2020s, driven by large-scale project pipelines in the North Sea, Taiwan Strait, and emerging markets across Southeast Asia and the United States East Coast. --- *Source: PR Newswire / Rainbowco Jiangsu Rainbow Heavy Industries Co., Ltd.*
