5 Certification and De-risking Marine Renewables Development Risk and reward define the capacity to attract finance (and the type of finance). Same applies regarding insurance. Standards and certification are key instruments to control risks to acceptable levels in a demonstrable way. provide all stakeholders with a degree of confidence (risk control) leading to trade facilitation, legal framework, supply chain and services development, insurance and capital costs reduction and efficiency and reliability improvement. Well established industries tend to have standards with high degree of prescriptive requirements as the technology is mature and the level of innovation is reduced or introduced in small incremental steps. Marine Renewables is in an early stage and requires a different approach that was established around the Technology Qualification process (DNV-OSS-312 first issued in 2008) providing a robust foundation for risk control and handling of uncertainties and novelty. For tidal, a further important step was given allowing DNV GL to keep the risk based approach but also to establish technical requirements providing the industry with a more predictable and effective process. 6

10 Summary The de-risking of the Marine Renewables sector requires a special approach regarding certification. Handling of uncertainties, novelty, safety, environment and functional requirements Risk based Gradual process Balance investments / targets vs. revenue (business model => Technical requirements: survivability, maintenance intervals and extent, fatigue) Use of existing technology that is compatible with marine renewables Lifecycle approach DNV GL provides a suitable framework for certification activities of marine renewable energy converters. Based on Technology Qualification process (generic, systematic, demonstrable, risk based and traceability) Handling of uncertainties, different concepts innovation Gradual process linked to natural flow of development Based on targets related to safety, environmental and functional requirements Use of existent knowledge (codes and standards) addressing most of the likely design requirements Lifecycle approach Slide 12

11 Summary The technical gaps are reflected on the approach to certification. The DNV GL certification process provides demonstrable risk management and clear identification of remaining risks Risk Based Certification is ideal to be integrated to project risk management Certification provides additional confidence to stakeholders as risks are reviewed through a structured process with third party oversight Certification s systematic adaptation of technology from Offshore Oil & Gas, Offshore Wind and Maritime and existing standards provides an effective and efficient way to develop technology and to make use of existing supply chain. The new DNV GL Service Specifications and Standards for Tidal and Wave Energy Converters will streamline certification and support the development of Marine Renewables Sector. Slide 13
