HYSY201船托管架滚轮组的结构改进

Modification Design of HYSY201 Stinger Roller Boxes Structure

结合深水海底管道铺设及深水管线结构物海上安装特点,研究并介绍了HYSY201船在出厂前对原托管架尾滚轮组及其他滚轮组优化设计的方法及理念,将传统的U型托管架尾滚轮组创新设计成V型尾滚轮组,并将其他所有滚轮组进行平滑设计,从而可以使管线结构物、卡环及锁具顺利通过滚轮组,有效降低了深水海底管道铺设及深水管线结构物安装的风险。该设计在HYSY201深水海底管道铺设及深水管线结构物安装中收到很好的效果。

HYSY201 has the ability to lay deepwater pipelines. Based on the characteristics of deepwater pipeline and pipeline in-line structure installation, we introduce the HYSY201 stinger roller boxes optimization design method and ideas. The stinger tail roller box is designed in a V shape instead of the traditional U shape. The pipeline in-line structure＇s slings and shackles can pass through the roller boxes effortlessly because of the modified roller boxes on the stinger. These designs can effectively reduce the risk of deepwater pipeline and pipeline in-line structure damage, also they have very good application during HYSY201 installation of deepwater pipeline and deepwater pipeline in-line structure.
