Experimental Study on Dynamic Response Characteristics of Moored Ships
During the terminal operation,the swell of more than 9 s have a relatively obvious impact on the mooring safety of the ship.In view of the possible risk of cable breakage,the response law of the wave period to the entire system consisting of the ship-mooring lines and fenders is discussed through physical model tests.The research results show that under the test conditions,the sway motion and roll motion are the control conditions that limit whether the ship can operate.Among all the lines,the bow transverse cable has the largest tension and is more likely to break the cable,which requires the staff to pay more attention during the operation and adjust the length in time.In addition,according to the limit conditions of movement and mooring force,the maximum allowable working wave height of the ship is evaluated in the study,and the test results can provide a certain basis for on-site operation.
