Wave & tidal power | Global test networks
International collaboration among marine energy test centres is shaping how ocean energy technologies are developed, regulated, and deployed, new report suggests
quickly. The report shows that lessons learned in one region, whether related to consenting, operations or environmental monitoring, are now informing decisions elsewhere. As a result, the network has become a mechanism for translating experience into practical guidance for developers, regulators and policymakers.
At the same time, the role of test centres has
broadened significantly. No longer limited to hosting devices, they are now positioned as key infrastructure for the sector, supporting innovation, reducing risk and providing data that underpins investment and regulation.
From single technologies to integrated hubs

THE INTERNATIONAL ENERGY Agency’s Ocean Energy Systems Technology Collaboration Programme (IEA-OES) has published a report drawing together more than a decade of experience from marine energy test centres worldwide. Compiled by the European Marine Energy Centre (EMEC), it reflects the work of the International WaTERS (Wave and Tidal Energy Test Sites) network, which was established in 2013 to connect open-sea facilities and accelerate learning across the sector. From its origins as a forum for knowledge exchange, the network has evolved into a structured platform addressing technical, regulatory, environmental and financial challenges. Participation has expanded across Europe, North America and Asia, with workshops and exchanges shaping a shared understanding of how to deploy ocean energy technologies more effectively. This collaboration has reduced duplication and helped test centres solve common problems more
One of the central findings is the transformation of test centres into multi-technology innovation hubs. Facilities originally designed for wave and tidal devices are now supporting floating wind, hydrogen production, energy storage and advanced monitoring systems. This reflects both changing market demand and wider energy system integration. The transition has required significant adaptation. Infrastructure built for single technologies has needed upgrading to accommodate new systems, while operational complexity has increased as centres manage a wider range of activities. Financial pressures have also been a factor, as diversification often requires upfront investment without guaranteed returns. In response, many centres have developed flexible service models, partnerships and consultancy offerings to remain viable. Alongside this shift, offshore operations have become more sophisticated. Harsh marine environments continue to present challenges, from unpredictable weather windows to seabed variability and limited vessel access. However, test centres have increasingly adopted digital tools, remote monitoring systems and autonomous vehicles to improve efficiency. Lessons from offshore wind, oil and gas and aquaculture have also been integrated, particularly in areas such as cable management and logistics. Importantly, the network has created a culture
of shared operational learning. Centres exchange information on both successes and failures, including maintenance strategies, equipment issues and near- miss incidents. This collective knowledge base has helped reduce risk and improve performance across the sector, even as each site continues to require tailored approaches based on local conditions.
Regulation, environment and trust The report highlights certification and consenting as
persistent challenges. While international standards have developed, formal certification processes remain costly and complex, particularly for early- stage developers. To address this, many test centres
