适用于导管架拆除的新型通用吊装卡具分析

Applicability Analysis of New General Lifting Clamp for Jacket Removal

根据潜在拆除市场导管架的特点,设计一种新型通用吊装卡具用于导管架拆除。该卡具在陆地预制,海上安装无须焊接,可反复利用。以2种方案为例,论证该卡具设计的可行性,分析其适用的导管架范围。通过软件计算论证新设计卡具的结构形式切实可行、安全可靠,并分析其经济性和可操作性。结果表明,该卡具的安装工作量更少、经济性更高、适用性更强。该新型通用吊装卡具已申请专利,今后将广泛应用于导管架拆除市场。

Based on the characteristics of the jackets in the potential removal market,a new type of general lifting clamp is designed for the removal of jackets.The clamp is prefabricated on land,does not need welding for offshore installation and can be reused.Using two options as examples,the feasibility of the clamp design is demonstrated and the range of the applicable jacket of the clamp is analyzed.The structural form of the newly designed clamp is proved to be practical,feasible,safe and reliable by software calculations,and the economy and operability of the clamp are analyzed.The results show that the clamp is of less installation workload,higher economy and stronger applicability.The new general lifting clamp is patented and will be widely used for jacket removal.
