Description

technical field [0001] The present invention relates to the technical field of leakage of LNG fuel-powered ships, in particular to a method, device and computer-readable storage medium for calculating the probability of leakage accidents of LNG fuel-powered ships. Background technique [0002] At present, diesel fuel is mainly used in the power plant of my country's inland river ships, and the air pollutants emitted by it are seriously harmful to human health and the environment. The energy structure of ship fuel dominated by diesel seriously restricts the healthy development of the shipping industry. As energy and environmental issues have become the focus of attention around the world, how to effectively reduce the proportion of diesel in the energy structure and reduce the emission of air pollutants from ships is the key to building a green shipping economy development model with low energy consumption, low emissions, and low pollution. Problems that need to be solved urge...
