初步设计阶段邮船船体钢材重量估算方法

Cruise Hull Steel Weight Estimation Method for Preliminary Design

基于2艘邮船的具体数据,通过统计学对比分析方法对几种船舶钢材估算方法在邮船上的适用性进行分析,并通过一元回归分析方法,针对沃森法采用的通用钢材重量估算曲线,对客船数据进行修正,回归出一种在邮船设计初期的船体钢材重量估算公式。经过邮轮实船数据检验,该估算公式误差较小,可为国内邮船设计中的空船重量分配和重量控制目标等关键指标的确定提供参考。

Based on the data of two cruise ships, the statistic method is used to analyze and discuss the application feasibility of the several estimation methods on cruise ships, and by single variable regression analysis, based on the general steel weight estimation curve of Watson’s method, the correction especially for passenger ships is carried out, and one cruise hull steel weight regression formula is proposed for the preliminary design stage. The error of this estimation formula is small after cruise ship data verification, which can provide technical support for the lightship weight distribution and weight control target for the domestic cruise ship design.
