Abstract
With tidal industry still having not achieved high Technology Readiness Levels (TRL), it becomes a pertinent task for developers, investors and operators to develop a widely agreed risk register in order to efficiently control residual risks towards further development. Scarcity and sensitivity of available data and limited synergy between industry agents constitute the task of stakeholder and risk identification quite difficult with relevant studies performed so far focusing specifically on individual sectors of the industry. This paper adopts a PESTLE approach to categorise the different sectors of the tidal industry, identifying key stakeholders and listing the risks considered most relevant. Outputs of this analysis stand as a basis for a targeted survey among stakeholders highlight the most critical risks through multi-criteria assessment in order to establish effective mitigation strategies that allow focus to be placed upon the most critical risks as perceived by the industry cumulatively.
