Bin Ye, Jiawei Yu, Zhiguo Zhang, Xin Long, Dakui Feng
Proc. ASME. OMAE2022, Volume 7: CFD and FSI, V007T08A048, June 5–10, 2022
Paper No: OMAE2022-79772
DOI: https://doi.org/10.1115/OMAE2022-79772
... is caculated and compared with the towing tank results, and the numerical uncertainty is studied, and then, full-scale self-propulsion performance of the tanker has been simulated. Besides, the sea-trial results of the tanker have been analyzed and corrected to the ideal conditions based on the ITTC sea-trial...

Improved ITTC Uncertainty Analysis Method of Ship Model Self-Propulsion Tests

Li Zhang, Jianting Chen, Chuanming Zhou, Weimin Chen
Proc. ASME. OMAE2020, Volume 6A: Ocean Engineering, V06AT06A052, August 3–7, 2020
Paper No: OMAE2020-19285
DOI: https://doi.org/10.1115/OMAE2020-19285
... Abstract In this paper, the uncertainty analysis method of ITTC (2017) for ship model self-propulsion tests was studied, and the defects of the ITTC method were analyzed, which didn’t provide the method to analyze the tests results at different temperatures. Combined with the ship model self...
