Abstract: To systematically review the technological progress of international water resource and hydropower engineering survey and design, as well as summarize the experience, based on typical case studies and multi-dimensional comparisons, this paper analyzed the key issues in the entire survey and design process from the perspectives of geological survey, design depth, technical risks, digital technology applications (BIM, GIS and remote sensing), and international standard integration (FIDIC clauses and CE certification).Combined with the practice of Chinese enterprises' Going Global projects, technical adaptability optimization and risk management strategies were extracted.The survey and design of international water resource and hydropower projects need to establish a collaborative framework of technological autonomy-ecological friendliness-social inclusiveness, promote the international certification of Chinese standards and the sharing of cross-border engineering databases, strengthen the cultivation of composite talents (technology + international law + language) and carry out full cycle risk management, achieve a strategic transformation from 'engineering delivery' to 'standard leadership', and contribute systematic solutions to the global energy low-carbon transformation.
