Abstract: The accurate prediction of the added resistance in waves has an important impact on the power correction of the full-scale ship, and it needs to be properly eliminated to accurately evaluate whether the speed at the agreed power meets the requirements. The MEPC 79 meeting held in December 2022 officially recognized the ITTC 2021 version of the “Preparation, Conduct and Analysis of Speed/Power Trials” as a statutory procedure, and the SNNM method for the prediction of the added resistance of ships in waves of arbitrary heading was introduced to fill the gap of current prediction methods. The influences of the period, wave direction, wave spectrum and the shape of RAO curve on the SNNM method have been examined in detail for the power correction in sea trials.

Key words: waves of arbitrary heading, new method for predicting added resistance in waves, sea trial, application

摘要： 波浪增阻的正确预报对实船的功率修正具有重要影响,需要恰当消除才能准确评价约定功率下的航速是否达到要求。2022年12月召开的MEPC 79会议正式将ITTC 2021版“实船航速测试分析规程”确定为法定规程,该规程引入了全浪向波浪增阻预报方法SNNM,弥补了现有波浪增阻预报方法的局限。该文重点研究了周期、浪向、波谱以及RAO曲线形状等因素对SNNM预报方法的影响,可用于指导实船试航的功率修正。
