This study developed a method for simulating greenhouse gas (GHG) emissions considering changes in conditions that may occur during the actual operation of small ships. Additionally, we analyzed and compared the results of the proposed method with that of existing emission simulations according to life-cycle assessment (LCA), thus verifying the proposed method’s effectiveness. Through the results of the study, we confirmed that the proposed method improves the simulation by considering emissions due to ship operation, whereas existing methods focus on emissions caused by raw material production. Additionally, the proposed method could identify and quantify the relationship between changes in operating conditions and GHG emissions. We expect this GHG emissions simulation technique to help improve the environmental performance of ships in the future.

这项研究开发了一种模拟温室气体（GHG）排放的方法，该方法考虑了在小型船舶实际运行过程中可能发生的状况变化。此外，我们根据生命周期评估（LCA）对所提方法的结果与现有排放模拟的结果进行了分析和比较，从而验证了所提方法的有效性。通过研究结果，我们确认了所提出的方法通过考虑船舶运行造成的排放来改善了模拟，而现有方法则着重于原材料生产引起的排放。此外，所提出的方法可以识别和量化运行条件变化与温室气体排放之间的关系。我们希望这种温室气体排放模拟技术能够在将来帮助改善船舶的环境性能。
