CITIC Offshore Helicopter Co., Ltd. CITIC Offshore Helicopter Co., Ltd. (000099.SZ) operates as China's leading provider of general aviation services, primarily supporting the offshore oil and gas industry through helicopter transportation, alongside emergency rescue, port pilotage, land navigation, navigation maintenance, offshore wind power support, aviation maintenance, and emerging drone operations. The company maintains a fleet of approximately 84 helicopters—including models such as Eurocopter EC155B1, EC225LP, AS332L2, Sikorsky S-92, Airbus H225, and others—plus 11 drones, conducting over 50,000 flight hours annually while serving key clients like China National Offshore Oil Corporation for deep-sea strategies; it holds exclusive status as the sole nationwide supplier of helicopter pilots for Chinese ports and extends operations internationally in offshore oil flights. Headquartered in Shenzhen, Guangdong Province, with major bases in Zhanjiang, Shanghai, Tianjin, and Beijing, the company was founded in 1983 as the predecessor to China Marine Helicopter Professional Company and functions as a subsidiary within CITIC Group, targeting energy, maritime safety, power transmission, and low-altitude economy sectors across China and select global offshore regions. In recent developments, CITIC Offshore Helicopter launched a regular Shenzhen-Zhuhai helicopter route and completed inaugural test flights for direct Shenzhen-Hong Kong cross-border service in 2024, while expanding into new markets by serving Hong Kong's CLP Power with equipment transport from Daya Bay to Tai Po; the company also signed lease agreements with Milestone Aviation Group in early 2024 for two additional Sikorsky S-92 helicopters and one Airbus H225 to bolster its offshore oil and gas fleet, bringing the total leased from Milestone to six aircraft and reinforcing its decade-long partnership. These initiatives underscore ongoing fleet modernization, safety achievements with zero incident rates per 10,000 flights, and strategic positioning in China's burgeoning low-altitude economy and offshore energy infrastructure.
