数字孪生技术作为一项革命性工具，通过构建实体资产、流程或系统的动态虚拟副本，已在多个领域实现复杂系统的精准建模与仿真。随着技术应用的不断深化，数字孪生正逐步成为关键决策的核心支撑。海上设施数字孪生系统相关技术因海洋环境的复杂性、海上设施的高风险性以及海上设施全生命周期管理需求等因素，呈现出显著的特殊性。本研究系统梳理了海上设施数字孪生系统的特点，总结了海上设施数字孪生系统测试、评估、验证与确认（TEVV）的主要关注点，并提出一套适用的TEVV技术框架，为海上设施数字孪生系统的质量保障提供了系统化解决方案。

As a revolutionary tool， digital twin technology enables the creation of dynamic virtual replicas of physical assets， processes， or systems， allowing for precise modeling and simulation of complex systems in various fields. With the continuous deepening of its applications， digital twin technology is gradually becoming a crucial support for key decision-making processes. The digital twin system technology for offshore facilities exhibits distinct characteristics due to factors such as the complexity of the marine environment， the high-risk nature of offshore facilities， and the requirements for managing offshore facilities throughout their lifecycle. This study systematically outlines the characteristics of the digital twin system for offshore facilities， summarizes the primary focus areas for testing， evaluation， verification， and validation (TEVV) of these systems， and proposes a suitable TEVV technical framework. This provides a systematic solution for ensuring the quality of digital twin systems for offshore facilities.
