海洋铺管船用张紧器整体吊装可靠性分析

Reliability analysis for tensioner integral hoisting of marine pipe laying barge

主支架是深海铺管船用张紧器重要的组成设备之一,它除了在使用过程中起到张紧器的安装与定位作用外,还要为张紧器的整体吊装起到支撑作用。在船用张紧器技术的国产化过程中,张紧器的整体吊装是非常重要的一个技术环节。张紧器在吊装的过程中,主支架的结构强度能否承载张紧器整体重量是需要分析的重点。通过ansys有限元分析软件对船用张紧器整体吊装时的主要受力部位和危险截面进行分析和计算,以此来验证船用张紧器整体吊装的可靠性。

The main frame is one of important composition of Marine Tensioner on the barge for lay-ing oil pipeline in deep sea,which is applied to mount and position the tensioner on one hand and to sup-port the hoist of integral Marine Tensioner on the other hand.In the process of localizing the Marine Ten-sioner,the integral hoisting of Marine Tensioner is a very important technical link,in which structural strength of main frame for bearing overall weight of Marine Tensioner is a key point to be analyzed.By AN SYS software,the article the main stress spot and dangerous section in the process of hoisting analyzed and computed to confirm the reliability of hoisting of Marine Tensioner.
