数字孪生概念的特点是模仿物理对应物的高保真度，为下一代先进船舶提供了潜在的好处。它可以分析数据并监控海洋系统，以避免问题发生，并通过模拟来规划未来。然而，与异构系统和硬件、内存和 CPU 利用率的集成相关的问题使得以单一或集中的方式实现这样的数字孪生是不可取的。联合仿真解决了这个问题，允许不同的子系统独立建模，但同时进行仿真。本文介绍了通过应用联合仿真和相关标准来实现 Gunnerus 研究船数字孪生的正在进行的工作。该论文并未提供完整的、即用型的数字孪生。相反，它介绍了用于实现这一目标的初步结果、程序和支持技术。为了实现这一目标，提出了一种由挪威海事行业成员合作开发的新颖的联合仿真解决方案。此外，还利用从 Gunnerus 获得的预先记录的传感器数据进行了机动案例研究。通过与真实机动在速度、航向和功耗方面的对比研究，对所提出的方法进行了仿真验证。
The concept of digital twins, characterized by the high fidelity with which they mimic their physical counterpart, provide potential benefits for the next generation of advanced ships. It allows analysis of data and monitoring of marine systems to avoid problems before they occur, and plan for the future by using simulations. However, issues related to integration of heterogeneous systems and hardware, memory, and CPU utilization makes implementing such a digital twin in a monolithic or centralized manner undesirable. Co-simulation addresses this problem, allowing different sub-systems to be modelled independently, but simulated together. This paper presents the ongoing work towards realizing a digital twin of the Gunnerus research vessel by applying co-simulation and related standards. The paper does not present a complete, ready-to-use digital twin. Rather it presents the preliminary results, procedure, and enabling technologies used towards realizing one. In order to accommodate this goal, a novel co-simulation solution, developed in cooperation by members of the Norwegian maritime industry, is presented. Furthermore, a maneuvering case-study is carried out, utilizing pre-recorded sensor data obtained from the Gunnerus. Through a comparative study with the real maneuver in terms of speed, course, and power consumption, the proposed approach is verified in simulation.
