R&D Overview
Subsea 7’s R&D activities focus on improving offshore energy solutions through digital innovation, advanced engineering, and proprietary technologies. The company holds nearly 2,000 patents and continued developing technologies such as 4Insight, a digital platform from 4Subsea that uses real-time data and analytics to improve vessel performance, and Ocean Plan, a software tool for offshore field design, cost optimization, and emissions modeling. The company also continued developing its proprietary Ocean Plan platform, which helps clients optimize offshore field designs, costs, and emissions. In addition, Subsea 7 advanced high-pressure 20K subsea pipeline technology, industry-leading welding capabilities, Electrically Heat-Traced Flowlines (EHTF), and proprietary bundle pipeline solution. The company is also investing in future energy technologies, including offshore wind, carbon capture and storage (CCS), hydrogen, electrification, and energy storage solutions. R&D spending supported projects related to hydrogen storage and carbon capture, aligning with the energy transition strategy. While the report highlights a strong patent portfolio and several proprietary technologies, it does not mention any new patents, trademarks, or copyrights granted during the year. However, branded technologies such as 4Insight, Ocean Plan, Subsea7, Seaway7, Xodus, and 4Subsea remain important intellectual-property assets supporting the company’s innovation and competitive advantage. In FY2025, the company incurred a research and development cost of US$12.8 million which was 0.2% of the company’s total revenue.
