The invention relates to the technical field of hydrogen safety assessment, and discloses a hydrogen leakage safety assessment method and device, computer equipment and a storage medium, the safety assessment process is divided into the steps of firstly assessing whether a hydrogen-powered ship needs to be in shore immediately and stop cruising after a leakage accident occurs, if not, continuing cruising, and if not, continuing cruising; according to the method, two evaluation processes of target hydrogen leakage safety evaluation results are further determined, and meanwhile, in the safety evaluation process, the influence rule of the flow degree of the hydrogen flow of a pressure reducing valve on leakage accidents in the cruising process of the hydrogen-driven ship after leakage of the hydrogen-driven ship is measured by utilizing the buoyancy characteristic number; and the accuracy of the target hydrogen leakage safety assessment result is improved.

    本发明涉及氢气安全评估技术领域,公开了一种氢气泄漏安全评估方法、装置、计算机设备及存储介质,本发明将安全评估过程拆分为先评估发生泄漏事故后氢动力船是否需要即刻靠岸并停止巡航,如不需要靠岸则继续巡航,并进一步确定目标氢气泄漏安全评估结果的两个评估过程,同时,在安全评估过程中,利用浮力特征数衡量氢动力船舶泄漏后减压阀氢气流量的流动程度对氢动力船舶巡航过程所发生泄漏事故的影响规律,提高了目标氢气泄漏安全评估结果的准确度。
