have introduced staged verification pathways, allowing technologies to progress gradually from non-accredited trials to full certification. This approach lowers barriers to entry while maintaining a route to compliance. Environmental monitoring and consenting present another layer of complexity. Regulatory requirements vary widely between countries, and permitting processes can be slow and uncertain. In some cases, developers are required to demonstrate minimal risk before deployment, which can delay projects. Test centres have responded by promoting adaptive, risk- based approaches, including “survey, deploy, monitor” models that allow for learning during deployment rather than requiring complete certainty upfront. Pre-consented testing zones have also emerged as a practical solution, reducing administrative burdens and providing flexibility. At the same time, test centres have taken a leading role in advancing environmental monitoring techniques and advocating for greater data sharing. Standardising monitoring protocols and improving interoperability are seen as critical steps in reducing regulatory friction. Beyond regulation, stakeholder engagement has become a strategic priority. Early and transparent interaction with communities, fisheries and environmental groups is now essential for securing social licence. Test centres increasingly act as conveners, facilitating dialogue and building trust through continuous engagement, education initiatives and clear communication. The shift from reactive consultation to proactive engagement has been a defining change, helping to reduce conflict and support project development.


Collaboration, funding and the


path forward Collaboration remains the defining strength of the International WaTERS network. Over time, test centres have developed shared tools such as databases, risk registers and lessons-learned logs, enabling the exchange of information on technical performance, safety and environmental impacts. Initiatives including staff exchanges, joint procurement and collaborative research projects have further strengthened connections across the network.


However, barriers to collaboration persist.


Differences in data formats, concerns over confidentiality and the absence of standardised platforms can limit information sharing. The report calls for clearer governance frameworks and incentives to support more open and structured collaboration, alongside continued investment in digital infrastructure and shared systems.


Funding is another ongoing challenge. Many test


centres operate on a mix of public funding, project- based grants and developer fees, creating uncertainty and limiting long-term planning. The early-stage nature of many marine energy technologies means that commercial revenues remain limited, placing additional pressure on test centre finances. In response, centres are increasingly adopting diversified funding models and positioning themselves as strategic assets within the energy transition. The report’s policy recommendations reflect these


realities. They emphasise the need for adaptive regulation, streamlined consenting, investment in infrastructure and support for data sharing. Recognising test centres as critical enablers of innovation is seen as key to accelerating deployment and reducing risk for developers and investors. Looking ahead, the priorities are clear: expand


shared resources, strengthen international collaboration, and continue to integrate emerging technologies such as hydrogen and floating wind. The experience of the WaTERS network shows that coordinated action and evidence-based planning are essential for progress. As marine energy moves closer to commercial maturity, the role of test centres – and the value of collaboration between them – will only increase.
