As a qualified supplier of CNOOC, Weite Technology Co., Ltd. has developed a crane safety protection system for marine conditions, which has been widely used in more than 80% of CNOOC's offshore drilling platforms.

Offshore Oil Engineering (Qingdao) Co., Ltd., a state-controlled subsidiary of China National Offshore Oil Corporation (CNOOC), specializes in the manufacture of offshore oil and gas engineering equipment. It is one of the largest offshore engineering manufacturing bases in Asia. The company's products cover pile-based offshore platforms, FPSOs, and offshore wind power facilities. The company has participated in the construction of landmark projects such as the "Deep Sea No. 1" energy station and the "Anemone No. 1" cylindrical production platform.

FPSOs (Floating Production, Storage and Offloading) are core equipment for deepwater oil and gas development. Their transmission cables are the critical "lifeline" connecting the FPSO to shuttle tankers, fulfilling both the FPSO's mooring and positioning duties and the oil and gas transmission mission. Due to their long-term exposure to harsh deepwater environments such as high salinity, high humidity, strong winds and waves, and strong currents, cables are susceptible to fatigue damage, corrosion, and localized fractures. Failures can lead to major safety incidents such as oil and gas leaks and equipment collisions. Therefore, online monitoring of transmission cables has become a core technology for ensuring the safe operation of FPSOs.

On September 27, the first 80-meter prefabricated box girder of the Hangzhou Bay Cross-Sea Railway Bridge was successfully erected, marking the full entry into the girder erection phase of the world's longest high-speed sea-crossing railway bridge. This "world's most powerful beam," measuring 78.2 meters long and weighing 2,800 tons – equivalent to the weight of over 2,000 cars – was erected in the strong tidal conditions of the bay, creating a new level of difficulty in its installation.
