摘要：

Within the framework of the Sustainable Development Goals, the United Nations (UN) General Assembly has declared its firm intention to combat climate change and the associated changes in the environment. Shipping is an important factor since its exhaust gases account for just over two per cent of global greenhouse gas (GHG) emissions. Liquid hydrogen is a promising candidate to enable this transition. In this work, a simulation-based approach for the estimation of design loads with respect to liquid hydrogen fuel tanks is presented. The MATLAB software was employed to implement a 0-dimensional approach for the calculation of the bulk thermodynamic behavior. There is good correlation between validation data and simulation. An exemplary cruise ship and corresponding power-demand profiles were utilized to simulate different fuel gas supply systems. The results were then analyzed with regard to occurring loads and operational efficiency.
