Optimization design method and application for LNG harbor basin layout based on digital twin

为了实现港池水域设计与数字化的融合,优化港池水域平面设计方案,提高LNG船舶进出港的安全性,研究了一种基于数字孪生技术的LNG码头港池水域平面布置设计优化方案。依据LNG船舶和港作拖轮的实体特性,提取几何特征和水动力参数,构建孪生虚拟模型,应用感知数据技术,建立虚实映射关联模型,将LNG船舶和港作拖轮实际的运动状态,与智能数字化的技术精准融合,并在所搭建的虚拟环境中完成进出港和靠离泊测试,根据试验结果优化进出港航道及码头平面布置的设计方案,实现数字孪生技术在LNG码头设计过程的应用。

In order to integrate the design of harbor basin water area with digitalization,optimize the habor basin water area plane design scheme,and improve the safety of LNG ships entering and exiting the port,a design optimization scheme based on digital twin technology for LNG terminals was studied.Based on the physical characteristics of LNG ships and harbor tugs,geometric features and hydrodynamic parameters were extracted to construct a digital twin model.By applying perception data technology,a virtual-real mapping correlation model was established,accurately integrating the actual movement status of LNG ships and harbor tugs with intelligent digital technology.The virtual environment was used to conduct docking and departure tests,and based on the test results,a design scheme for the optimization of the layout of the terminal and the docking channel was developed.The application of digital twin technology in the design process of LNG terminals was thus realized.
