摘　　要：在对实船试航过程中实测的航速和功率进行修正时,波浪修正是重点之一。基于此,对ISO 15016:2015中的波浪修正方法、我国在国际海事组织(International Maritime Organization,IMO)会议上提出的波浪增阻预报方法及二者相结合形成的组合方法进行对比分析。以某5万吨级散货船为研究对象,采用上述方法计算波浪增阻,并将各结果与试验结果相对比。结果表明:波浪周期对波浪修正结果的影响较大;采用组合方法所得预报结果总体上与试验所得预报结果较为接近。Wave correction is one of the most important parts in ship trial speed correction. This paper studies three methods for predicting added resistance due to waves： the wave correction specified in ISO 15016：2015, the method submitted to IMO（International Maritime Organization） conference by China and the combination of both. The calculations for a 50 000 t bulk carrier are conducted for comparison. Meantime, the corresponding tests are performed. The analysis of the results shows that the accuracy of the correction methods is greatly affected by the wave period, and the combined method gives the best prediction in general.
