摘要
在FPSO船体集成过程中,温度和光照等环境因素对精度控制的影响不可忽视.以近期完工的国内某FPSO项目为例,研究了在干坞条件下,下塔体与船体集成时,船体月池中心点作为下塔体定位的基准点,受温度和光照等环境因素的影响,位置产生变化的现象.通过测量实验定性定量地分析了月池中心因环境变化而产生位置变化的原因和规律,进而提出在温度较为恒定的夜间时段进行下塔体精确定位和焊接施工的建议.
Abstract
In the process of FPSO hull integration,the influence of environmental factors such as temperature and illumination on accuracy control cannot be ignored.Taking a domestic FPSO project recently completed as an example,this paper studies the position change of the moonpool center,which is the fiducial point for positioning,influenced by environmental factors including temperature and illumination when the lower tower body is integrated with the hull on dry dockyard.Measurement experiments are conducted to qualitatively and quantitatively analyze the reasons and patterns of position changes in the center of the moonpool under environmental changes.In addition,the construction suggestion that precise positioning and welding of the lower tower body should be carried out during the night time with a constant temperature is proposed.
