摘　　要：通过分析孤立内波的分布及产生原因和动力定位船舶的作业原理,分析孤立内波对动力定位船舶作业的各种影响。结合多次应对内波工作的经验,从观测手段、作业前准备和现场应对等3方面论述相应的孤立内波应对措施。通过对某DP2级锚系作业工程船实际采用应对措施进行分析,验证这些措施的可行性。This paper discusses the influence of solitary internal wave on the dynamic positioning vessel in operation by analyzing the distribution and mechanism of solitary internal waves and the operation principles of Dynamic Positioning(DP)vessels.Based on the experience of dealing with internal waves,the countermeasures are elaborated from three aspects,i.e.,the observation approach,the pre-operation preparation and the on-site response.The feasibility of the measures is validated through the analysis of the actual countermeasure scheme for a DP2 mooring operation engineering vessel.
