On May 14th, the Hong Kong LNG project, for which COOEC is responsible for the general contracting, successfully completed its first ship unloading and pipeline purging. This signifies that the largest offshore energy infrastructure project in the Hong Kong Special Administrative Region (HKSAR) in recent years has successfully entered the trial operation stage. Upon completion, the project will significantly increase the proportion of clean energy generation in Hong Kong and is of great significance for optimizing the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area and assisting in achieving dual carbon goals.
The Hong Kong LNG project primarily includes a double-berth offshore LNG receiving station wharf in the form of a jacket, a land-based LNG receiving station, and two submarine pipelines. As the core project, the Hong Kong LNG receiving station is the world's largest offshore LNG receiving station. It employs the world's first offshore double-berth receiving station wharf with an all-steel structure, capable of accommodating operations of two of the world's largest Floating Storage Regasification Units (FSRU) or LNG carriers simultaneously. The wharf is designed for a 50-year service life, more than double that of conventional offshore LNG receiving stations, and can withstand 4.9 million docking impacts per year, each with a maximum force of 2,400 tons.
During the construction of the project, COOEC achieved nearly 30 technological innovations, completed the construction and installation of 28 single structures with a total weight of 35,000 tons in high quality, successfully traversed complex sea areas such as the Longgu shipping channel, the Hong Kong-Zhuhai-Macao Bridge, cable areas, and densely packed ship areas, and completed the laying of 63 kilometers of submarine pipelines, setting multiple new project records. Among them, the maximum trench depth reached 8 meters, four times the conventional sea pipe trench depth, accumulating valuable experience for ultra-deep trenching operations in China.
It is understood that COOEC has now developed the full industry chain construction capability for LNG projects, from gasification to liquefaction, and from land to sea. It is leading the world in areas such as super-large LNG storage tanks and offshore LNG receiving station engineering.
