Technical and Operational Impact
VERTI-GO delivers significant technical and operational impact by advancing floating vertical-axis wind turbine technology toward large-scale offshore deployment. The project demonstrates a 2 MW floating VAWT operating in real offshore conditions, enabling improvements in performance, reliability, and operational control. Through advanced control strategies and simulation-driven optimisation, VERTI-GO targets a 15–30% increase in energy production, primarily by reducing downtime and improving system responsiveness.
Reliability is strengthened through a drivetrain architecture that favours modularity over single large components, improving fault tolerance and allowing continued operation at reduced output in certain failure scenarios. This also streamlines maintenance by relying on smaller, standardised parts that are easier to handle and replace offshore. The integrated turbine and floating platform design, combined with a lower centre of gravity, simplifies construction and offshore assembly, improving scalability and ease of deployment. In addition, optimised spatial layouts enabled by VAWT characteristics allow closer turbine spacing, increasing power density by up to 190% compared to conventional horizontal-axis turbines, supporting more efficient use of offshore space. Overall, the approach is designed to remain adaptable; scaling and configuring effectively across different site conditions and application needs as floating offshore wind moves toward wider deployment.
Economic Significance
From an economic perspective, VERTI-GO contributes to cost reductions across the lifecycle of floating offshore wind projects. Improved energy production, reduced downtime, and optimised control systems are expected to result in up to 30% reduction in levelised cost of energy (LCOE). Capital expenditure benefits arise from lighter structures, simplified foundations, and streamlined on-site assembly and decommissioning, leading to an estimated 15–30% reduction in CAPEX. Operational expenditure is further reduced through improved accessibility and lower maintenance frequency, with 10–20% OPEX savings anticipated. This is supported by a maintenance-focused design that simplifies offshore interventions. SeaTwirl’s stall-regulated concept removes pitch- and yaw-systems, eliminating major maintenance drivers, while the fixed rotor structure and low rotational speed reduce wear-related risks such as blade erosion and associated service needs. In addition, service-critical mechanical and electrical components are located inside the Gendeck, positioned just above the waterline and below the wind turbine, enabling easier access for inspection and repair and reducing vessel time and operational complexity. The project also enhances material efficiency through recycling and circular manufacturing strategies, supporting cost-effective and resilient supply chains for future offshore wind developments.
Environmental Significance
VERTI-GO delivers strong environmental benefits by supporting the transition to low-carbon offshore energy while reducing impacts across the turbine lifecycle. The project adopts a circular design approach that prioritises material reuse, refurbishment, and recycling, including recyclable steel structures, reusable ballast, and bio-fibre composite materials. Lifecycle greenhouse gas emissions are expected to be reduced by 21–49%, driven by sustainable design choices and optimised operation and maintenance strategies. Offshore environmental impacts are further mitigated through reduced seabed disturbance enabled by lightweight anchoring systems and floating platforms. Continuous environmental monitoring and data sharing through platforms such as EMODNET and IEA Wind Task initiatives support transparency, ecosystem protection, and long-term marine stewardship.
Social Significance
VERTI-GO generates positive social impact by strengthening Europe’s offshore wind ecosystem and supporting regional economic development. The project reinforces European industrial leadership, with more than 50% of production activities based in Europe, enhancing supply chain resilience and local expertise. Local value creation is a key outcome, with 100% of project value retained within Europe, supporting regional economies and coastal communities. VERTI-GO also contributes to workforce development by fostering technical training and job creation in offshore manufacturing, logistics, and operations. Improved safety is achieved through comprehensive risk assessments, safer access strategies, and sustainable operational protocols, enhancing working conditions in challenging offshore environments.
