A two-dimensional mathematical model of tidal current is established and verified for the new 300,000-ton crude oil wharf in Dalian New Port. The ship's mooring forces are calculated based on the standard-velocity tide, the measured tide data and the simulated tidal current. Optimization scheme is proposed for the plane layout of the crude oil wharf in Dalian New Port. The results show that there is a transverse flow in the wharf apron and the maximum mooring force appears when the direction of tide flow in the recirculation zone is 63°~67°NbE, which increases the occurrence probability of the cable break. In order to reduce the mooring force, it is recommended that the orientation of the wharf axis should be deflected towards east by 16°~20°, and the temporary berthing operation of the 450,000-ton ship should avoid the time of 2–3 hours before the lowest tide level. The present study can also provide guidance for the layout optimization of other similar planned wharfs.
