The offshore wind industry is expected to be a major contributor to climate change mitigation and renewable energy transition. Supply chain challenges abound in realizing the potential of offshore wind development. This study focuses on devising supply chain strategies especially toward China, to help energy companies fulfil offshore wind development goals. Scaling up offshore wind requires a long-term view; therefore, scenario planning was utilized to help decision makers tackle uncertainties by preparing for several possible futures. Twelve key driving forces were identified. Three scenarios for 2030 and potential supply chain strategies were developed and surveyed in an energy company and an industry business network. Results show different focus areas of sourcing, construction, assembly and installation strategies based on markets and scenarios. The study contributes to decision making for shaping the future of offshore wind supply chain.
