Introduction

The technical maturity assessment of tidal current energy generation devices is based on the background of vigorously promoting the development of tidal current energy resources and the construction of demonstration projects in my country. To meet the needs of the development and technological innovation of the tidal current energy industry, make full use of the technology maturity theory, and combine the research and development and management of tidal current energy generation devices A set of evaluation methods and processes summed up from the company's experience to standardize the device development process, establish awareness of stage evaluation, and prevent new technology development risk, and promote the industrialization and engineering application of tidal current energy. Guidelines for Technology Maturity Assessment of Tidal Current Power Generation Devices

1 Scope

This document determines the level of technical maturity of tidal current energy generation devices, and describes the assessment dimensions, level conditions, stage assessment and assessment step. This document is applicable to the technical maturity assessment work at each stage of research and development of tidal current energy generation devices.
