Aiming at the problem that the traditional numerical simulation method is insufficiently representative to the navigation safety research under the complex wind，wave，and current conditions，we borrow the research methods of domestic large-scale hydropower projects and inland ports，use the method on-site actual vessel maneuvering test combining with multi-factor observation，take the third phase of the car and passenger ferry terminal project in Shenjiawan of Shengsi County as an example，conduct comprehensive observation of various influencing factors such as wind，waves，and currents，demonstrate the rationality of the research project layout，and propose the measures to ensure navigation safety combining with the ship position varying during berthing process. The results show that the measured scheme can accurately observe the influencing factors of ship handling safety，accurately quantify the data of influencing factors，and make full and reasonable use of shoreline resources on the premise of ensuring ship safety.
