With the demand to reduce the release of CO₂-rich gases into the atmosphere, the offshore industry is turning to systems for gas capture and storage. The construction of a cave for that purpose is planned in the salt layer of the Santos Basin, Brazil; however, numerous factors bring uncertainties to the project. We propose combining systems engineering methods and digital twin technology to enable system concept and execution aiming at value robustness. The system is modeled in mission, subsystems, components, and design attributes. System utilities and costs are estimated for a range of viable solutions based on the relevance of each attribute to the stakeholders. The alternatives are evaluated using the Epoch-Era Analysis framework for analyzing the system's performance over time in changing future scenarios. The system model also outlines a digital twin concept and identifies how it might support salt cave design and operations. Finally, the potential of tuning and improving system evaluation based on gathered data is examined, and measures toward further digital twin development are recommended.

利用划时代的分析和数字孪生实现有效的系统概念和执行：二氧化碳封存盐洞项目

_{随着减少向大气中释放富含CO 2}的气体的需求，海上工业正在转向气体捕获和储存系统。为此，计划在巴西桑托斯盆地的盐层中建造一个洞穴；但诸多因素给该项目带来了不确定性。我们建议将系统工程方法和数字孪生技术相结合，以实现旨在实现价值鲁棒性的系统概念和执行。该系统按照任务、子系统、组件和设计属性进行建模。根据每个属性与利益相关者的相关性，估算一系列可行解决方案的系统效用和成本。使用 Epoch-Era 分析框架来评估替代方案，以分析系统在不断变化的未来场景中的性能。该系统模型还概述了数字孪生概念，并确定了它如何支持盐洞设计和运营。最后，研究了基于收集的数据调整和改进系统评估的潜力，并提出了进一步数字孪生开发的措施。
