- 摘要:
- 岸拖施工是海底管道登陆的关键环节。在长距离岸拖施工中，传统方法采用线性绞车作为陆地拖拉设备，存在设备就位困难、资源稀缺、施工成本高昂等问题。在惠州乙烯原料管线项目中，创新性地采用“定向钻机与铺管船协同岸拖”的施工方法，并成功实现国内首次工程应用。系统阐述了该创新方法的工艺流程、关键控制点及设备选型原则，重点分析了钻机精准就位、管道回拖力计算、设备匹配优化及工艺参数校核等核心技术。此外，结合现场实测数据，验证了该技术的经济性及工程适用性，可为后续类似长距离、复杂地质条件下的岸拖施工提供可复制的工程实践经验与技术参考。
Shore-based towing construction is a critical phase in submarine pipeline landing operations. Traditional methods, particularly in long-distance shore-based towing construction, often rely on linear winches as the primary onshore towing equipment. However, these conventional approaches face challenges such as difficult equipment positioning, limited resource availability, and high construction costs. In the Huizhou’s ethylene feedstock pipeline project, an innovative construction method of “collaborative shore-based towing by directional drilling rig and pipelaying vessel” was successfully implemented, marking its first engineering application in China. This paper systematically elaborated on the process flow, key control points, and equipment selection criteria of this novel approach. It focused on core technologies, including precise positioning of the drilling rig, calculation of pipeline pullback force, equipment matching optimization, and verification of process parameters. Furthermore, based on field-measured data, the economic feasibility and engineering applicability of this technology were validated. The findings provide replicable engineering practices and technical references for future long-distance shore-based towing construction under complex geological conditions.
