摘要：	Typhoons and other extreme weather events frequently strike offshore fishing ports. Therefore, an objective and realistic assessment of the berthing capacity of fishing ports are critical to offshore production safety and the safe management of fishing ports to minimize typhoon effects. We integrated the MIKE 21 spectral wave (SW) and Holland wind models to recreate typhoon wave characteristics during the transit of Typhoon In-Fa and further analyzed the berthing capacity of the Shengsi fishing port (SFP) under different recurrence periods and route impacts. We planned the mooring area realistically and upgraded the marine fisheries production safety and security system. The model's major wave heights and water levels are consistent with the actual observations, and the d-trend model evaluation demonstrates that our model performs well. The berthing capacity of the SFP was accurately calculated based on the significant wave height and stable mooring conditions for fishing vessels. The effective berthing area within SFP reached 5.88 km2 during the typhoon transit, accounting for 89.3% of the harbor area. A total of 5,154 fishing vessels, comprising 492 large-sized fishing vessels, 2,334 medium-sized fishing vessels, and 1,328 small-sized fishing vessels, could be moored. The berthing capacity under the impact of typhoons with varying recurrence periods is boosted by 10% compared with that of a 100a typhoon. When under the influence of typhoons with distinct trajectories, the wider the sheltered area of SFP is due to the topography sheltering effect, the more southerly the typhoon path is. This article examines the impact of alternative typhoon routes and return periods on fishing port sheltering capacity. The MIKE 21 SW wave and the Holland typhoon models are adopted to simulate the wave characteristics of the waters surrounding the fishing ports during the occurrence of the typhoon to analyze the fishing ports' berthing capability. This report can be a reference for disaster reduction and offshore fishing port berthing management.
