A Bounded Near-Bottom Cruise Trajectory Planning Algorithm for Underwater Vehicles by Jingyu Ru, Han Yu, Hao Liu, Jiayuan Liu, Xiangyue Zhang, Hongli Xu

“…The currently used algorithms are not effective at solving length-constraint problems, and the mainstream trajectory planning algorithms for robots cannot be directly applied to the needs of underwater vehicle sailing near the bottom. Therefore, we present a bounded ridge-based trajectory planning algorithm (RA*) for an AUV to go on a near-bottom cruise. …”

Research on Sea Spray Distribution of Marine Vessels Based on SPH-FEM Coupling Numerical Simulation Method by Jiajing Chen, Xu Bai, Jialu Wang, Guanyu Chen, Tao Zhang

“…Due to the effect of the maritime environment and low temperature factor, ice phenomena are easily produced while a ship is sailing in a polar location. Types of ice accumulation include sea spray icing, which accounts for 90% of all ice accumulation, and, therefore, sea spray generation is a crucial step in ice accumulation prediction research. …”
