The LNG (liquefied natural gas) marine loading arm is an important oil and gas transportation equipment installed at the dock. In order to analyze the impact of the LNG marine loading arm under extreme typhoon weather and provide theoretical guidance for subsequent research and development, a three-dimensional model of the marine loading arm was established using Solidworks software and simulated using Fluent software. The SST K-omega turbulence model was selected, and a velocity inlet was written using UDF and a pressure outlet was selected. The SIMPLE solver was used to solve the model. The flow field model of the LNG marine loading arm was simulated, and it was found through data analysis that the structures with greater force were the rope wheel and the counterweight bracket. This provides a way of thinking for the subsequent optimization design of the LNG marine loading arm.
