- 摘要:
- 采用铺管船法进行海底管道的铺设，要求铺设速度快、焊接质量高，文章根据工程要求，结合标准规范，通过开展焊接工艺、喷淋工艺及CTOD断裂力学安全性评价技术的研究，成功将铺管船法施工技术应用于渤海湾NP1-29井组海底管道铺设项目中，由于技术先进，工艺恰当，海上施工工期大大缩短，质量提高，并形成了一套完整、高效、经济、可操作性强的海底管道焊接和安全性控制技术。
The fast laying speed and high welding quality are required in submarine pipeline laying with pipeline laying vessel.According to the requirements of engineering and regulations, the research on pipeline welding process, spraying process and safety assessment technique of CTOD rupture mechanics were conducted, then the laying method with pipeline laying vessel was successfully applied in the submarine pipeline laying project of Bohai Bay NP1-29 well group.The marine construction period was greatly shortened and the construction quality was boosted owing to the advanced techniques and correct processes.A set of integral, highly effective, economical and maneuverable techniques for submarine pipeline welding and safety control has been formed.2010,5(5): 25-28 收稿日期：2010-5-31分类号：TE973.3作者简介：牛虎理（1978-），男，河北石家庄人，工程师，2005年毕业于天津大学，工学硕士，现主要从事石油工程焊接设备和技术的研究开发工作。参考文献：
