Quality and Progress Control for Stinger-to-Hull Connection of Heavy Derrick Lay Barge-Lan Jian

蓝疆号起重铺管船是一艘集起重、管道铺设于一身的多功能新型船舶,在铺管作业系统中,设有一连接船体与托管架的独立结构——拖挂结构。介绍这个由特厚高强钢板组焊而成的结构在制造过程和现场施工中的质量控制及进度控制,供从事工程管理人员参考。

The Heavy Derrick/Pipe Lay Barge is designed for advanced performances of lifting and pipeline laying. The structure is installed for stinger to hull oonnection in pipeline laying system. The paper introduces detailed quality control and progress control of the welded structure which is composed of high-strength steel heavy plate, and provides some experiences for reference to the project quality management.
