为了实现海底输气管道维修的顺利、便捷、高效和经济作业,基于海上输气管道维修作业复杂性和特殊性的特点,以及输气管道维修中各个工序和关键路径,通过分析影响维修作业的各种因素,利用甘特图法对海底输气管道维修进度计划进行优化调整,建立了一套系统化的海上输气管道维修作业流程,并针对海底输气管道维修过程中的制约因素,提出了合理性的改进意见和实施措施。在一定条件下,该流程能够减少海底管道维修作业工期滞后的问题,降低海上维修作业带来的经济损失。
In order to achieve the smooth, convenient, efficient and economical operation of the seabed gas pipeline repairs, based on the complexity and particularity of the gas pipeline repairing operations and the various processes and critical routes in the gas pipeline repairs, Various factors, the use of Gantt chart optimization of submarine gas pipeline maintenance schedule, set up a systematic operation of the pipeline gas pipeline maintenance, and for the seabed gas pipeline maintenance process constraints, put forward Reasonable suggestions for improvement and implementation measures. Under certain conditions, the process can reduce the time lag of submarine pipeline maintenance operations and reduce the economic losses caused by offshore maintenance operations.
