In view of the problems such as incomplete reference standards，version updates，and limited ship type applications in ship wind load calculation，this paper selects four current mainstream industry standards of China，the United Kingdom，the United States，and OCIMF for analysis and takes a 20，000-ton general cargo ship as a case for comparison.The results show that the calculation results are quite different.For the lateral component force，the results by standards of the United Kingdom and the United States are close，and that by the standard of China is obviously larger.For the longitudinal component，the results by the standard of the United Kingdom are significantly greater than those by the standard of the United States in the case of stern wind，and the results by standards of China and the United Kingdom are close in the case of bow wind，and both are smaller than those by the standard of the United States.The paper suggests that the calculation methods should be reasonably selected according to factors such as the applicable ship type，the fullness of ship data，the main wind angle，and management requirements，and the numerical simulation method should be used when conditions permit.
