In order to understand the applicability of the speed correction method of the ITTC 2021, the experimental requirements and correction process of the speed correction method of this method during the test of ship speed are introduced and compared with those of the ISO 15016∶2015. Speed correction programs for the two methods are developed through programming based on the principle of speed correction. The trail data of three typical ship types are then analyzed by using the two correction methods, summarizing the effects of the two correction methods on the correction results under different environmental factors such as wind, wave, tide, temperature, density, and water depth. The results show that the correction method of the ITTC 2021 is more reasonable than that of the ISO 15016∶2015. And the resulting speed corrected by the ITTC 2021 method is slightly higher than that by the ISO 15016:2015 correction method for these three ship types, while the newly added correction method for the added resistance in waves is the main factor causing the difference of the analysis results.
