大型海洋石油平台组块滑移装船过程中滑道结构安全性评价

Security evaluate of skidway structures of large offshore platforms loadout process

随着海洋石油产业的蓬勃发展,海洋采油平台组块结构向大型化发展已成为必然趋势。然而中国现有的多数平台组块建造场地设计等级较低,已不能满足大吨位海洋平台组块的建造需要,多数场地的超负荷使用给安全生产带来巨大隐患。以采用滑块压柱式滑道装船为例,介绍高桩承台滑道在平台组块滑移装船过程中受力分析及安全评价的方法。

With the flourishing development of offshore oil industry,development of the enlargement of offshore plat- form becomes inevitable.However,the lower design grade of most sites tor oftshore platform construction can not meet the constructional requirement of large offshore platforms.Overload of most of the sites brings much hidden trouble to security production.Taking column skidway as an expmple,method of mechanical analysis and satety evaluation for elevated pile foundation skidway in the process of slippa...
