在镇央企中交二航局三公司承建 协鑫汇东江苏如东LNG接收站取排水工程顺利交工验收

Core Viewpoint - The successful completion of the LNG receiving station's water intake and drainage project in Jiangsu, undertaken by China Communications Construction Company, marks a significant milestone in the construction of the LNG receiving station, contributing to energy supply and resource utilization [1][2]. Group 1: Project Details - The project is located in Yanggu Island, Nantong Port, Jiangsu Province, and includes the construction of water intake structures such as intake and drainage heads, pipelines, pump houses, drainage wells, and navigation aids [1]. - Major construction challenges included sinking a caisson to a depth of 30 meters, a 930-meter long pipe jacking, and excavating 360,000 cubic meters of seabed [1]. - A technical team was formed to address these challenges, optimizing the sinking process from three adjustments to two, and dividing the caisson into four areas for efficient excavation [1]. Group 2: Engineering Achievements - The project achieved both quality and schedule standards through scientific organization and design optimization by the technical team, leading to successful project completion on October 31 [2]. - The heat exchange process between seawater and liquefied natural gas (LNG) not only facilitates the gasification and export of LNG but also highlights the energy value of the low-temperature seawater, laying the groundwork for future cold energy utilization [2].
