The equations about longitudinal and transverse forces acting on vessel and vessel motion were established considering coupling relationship between flow and vessel. On the basis of the theory, a set of parallel computation program for numerical simulation of vessel hawser forces and vessel motion in a lock chamber was successfully compiled with the help of user defined function(UDF). Using the software FLU-ENT and RNG k-ε model for turbulence flow, the numerical simulation for vessel hawser forces of a whole concentrated filling and emptying system with a energy dissipation room and grating holes were conducted by using the VOF method and dynamic mesh technology. According to the comparison of experimental and calculated data, the verification results showed that the simulation method for vessel hawser forces was rea-sonable and the calculation accuracy was satisfactory. The vessel hawser forces with and without auxiliary energy dissipaters in a energy dissipation room were simulated, and the function and effect of the auxiliary energy dissipaters were analyzed.
