The Hong Kong liquefied natural gas (LNG) project entered into trial operation on Sunday and is expected to significantly increase the proportion of clean energy generation in Hong Kong Special Administrative Region while optimizing the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area, said its operator China Offshore Oil Engineering Co Ltd.

As the largest offshore energy infrastructure construction project in recent years in Hong Kong, the Hong Kong LNG project includes a dual-berth offshore LNG receiving terminal, an onshore LNG receiving terminal and two submarine pipelines, according to the company, a listed company controlled by China National Offshore Oil Corporation.

LNG transport ships will provide stable and clean power generation fuel to Hong Kong via submarine pipelines, it said.

As the core project of the Hong Kong LNG project, the LNG receiving terminal is the world's first offshore all-steel structure double-berth receiving terminal, capable of accommodating two of the world's largest FSRUs (floating storage and regasification units) or LNG transport ships for berthing and operation at the same time, said Liu Zhigang, COOEC Hong Kong Offshore LNG Terminal EPC project deputy director.

The designed service life of the terminal is 50 years, which is more than twice that of conventional offshore LNG receiving terminals, he said.

CNOOC currently has formed a complete LNG engineering construction capability from liquefaction to regasification onshore and offshore. It ranks among the top of the world in large-scale LNG modularization, super large storage tanks and receiving terminal construction for LNG.

The company vows to continue strengthening the key core technology research and development of clean energy engineering in the years to come and contribute to promoting China's energy structure transformation and the realization of the dual-carbon goals.
