风电安装船主尺度要素统计分析

Statistical analysis of principal dimensions of wind power installation vessel

船舶主尺度决定了船舶的经济与技术特性,如稳性、操纵性、快速性、载重量、造价等.在船舶设计过程中,确定主尺度是船型方案设计第一阶段,是后续技术设计的重要基础.在对第三代风电安装船特点进行理论分析的基础上,搜集整理了目前世界范围内第三代风电安装船主尺度资料,分析了风电安装船各个主尺度对载重量敏感性的变化规律和特点.结合实践经验,运用统计学方法回归出了一套主尺度计算公式,并进行了稳定性验证,该公式可供船东选择最佳船型尺度时和设计部门进行方案设计时或者进行船型技术经济性能论证时参考.

The ship,s principal dimensions determine the economic and technical characteristics of the ship,such as stability, maneuverabi lity, speed, dead weight, cost and so on . In the process of ship design, it is confirmed that the determination of principal dimension is the first stage of ship design, and it is an important foundation for the follow-up technical design. The characteristics of wind power installation vessels （Generation IE ） are analyzed the oretically, and worldwide in formation about principal dimensions data of wind power installation vessels at present is collected and sorted. The sensitivity of each principal dimension to deadweight is analyzed. A new solution to hull principal dimensions is regressed based on statistics and practical experience, and its reliability is tested and proven. It can be used as a reference when doing project design by designers or selecting the optimal principal dimensions by shipowners. In addition, it cnalso help to carry out technical economic performance discussion.
