The invention provides a method for judging loading and unloading working conditions of an LNG transport ship and a system thereof. The method comprises the following steps: acquiring an operation state of a propeller of the LNG transport ship; based on the operation state, judging whether the LNG transport ship is in a maneuvering working condition or not; if not, obtaining distance information between the LNG transport ship and the destination port; obtaining the standard deviation and the variable quantity of the liquid level of the cargo hold of the LNG transport ship in the preset period; and based on the distance information, judging the standard deviation and the variable quantity, the target working condition of the LNG transport ship; wherein the target working condition comprises any one of the loading working condition and the unloading working condition. The technical problem that in the prior art, it is difficult for managers to conduct safety management on the liquefied natural gas transport ship under the loading and unloading working condition through data analysis is solved.

    本发明提供了一种LNG运输船舶装卸货工况判断方法和系统,包括:获取LNG运输船舶的推进器的运行状态;基于运行状态,判断LNG运输船舶是否处于机动工况;如果否,则获取LNG运输船舶与目的港之间的距离信息;获取LNG运输船舶的货舱液位在预设周期内的标准差和变化量;基于距离信息、标准差和变化量,判断LNG运输船舶的目标工况;目标工况包括以下任一项:装货工况,卸货工况。本发明缓解了现有技术中存在的管理人员难以通过数据分析对液化天然气运输船舶进行装卸货工况时的安全性管理的技术问题。
