The authors regret the following errors in the original publication and would like to make the necessary corrections: 1. The acknowledgment statement should read as follows: Acknowledgments: We very appreciate Shoei Kisen for cooperating on the measurement. This study was financially supported by the National Natural Science Foundation of China, China (No. 52201416), the Fundamental Research Funds for the Central Universities (No.WUT: 223112001), Natural Science Foundation of Hubei Province (No. 2023AFD099), and Scientific Research (B) (Project No. 20H02398, 2020–2024, represented by Kenji Sasa) under Grants-in-Aid for Scientific Research, Japan Society for the Promotion of Science.2. In Section 2.1, the first sentence of the first paragraph should read as follows: The data employed in this study were derived from a bulker carrier, encompassing 8780 raw voyage data points spanning August 2015 and July 2016.3. In Section 2.2, the last sentence of the third paragraph should read as follows: The relevant parameters of the vessel are shown in Table 2.4. Fig. 1 caption should read as follow: Fig. 1. Annual Trajectory of the bulker carrier (From August 2015 to July 2016).5. Table 1 needs to be modified and the correction version of Table 1 and its caption is placed below. [Table presented] 6. Fig. 2 caption should read as follows: Fig. 2. Trajectory and fuel consumption of vessel.7. Table 2 caption should read as follows: Table 2. Attained CII parameters of the vessel.8. Fig. 6 needs to be modified and the corrected version of Fig. 6 is placed below. [Figure presented] The authors would like to apologise for any inconvenience caused.
