Qingdao Pacific Underwater Technology Engineering Co.

What Qingdao Pacific Underwater Technology Engineering Co. does

Qingdao Pacific Underwater Technology Engineering Co. (青岛太平洋水下科技工程有限公司) is a Chinese specialized commercial diving and underwater engineering services provider headquartered in Qingdao, Shandong Province. The company was incorporated in 2017 as a survival-type spin-off of the underwater engineering division of Qingdao Pacific Ocean Engineering Co., which had operated in the underwater services field since 1992. It carries forward 30+ years of accumulated certifications, equipment, and project history from the parent lineage and now operates with 51-100 employees and RMB 20 million registered capital. Its core technical capabilities span three deep-water modalities: an Atmospheric Diving System (ADS) rated to 600m depth with 3-4 hours per dive, helium-oxygen mixed-gas diving for 120-200m operations, and Remotely Operated Vehicle (ROV) deployment with mechanical arms for high-risk tasks. Complementary proprietary methods include a needle-array (pin-needle) millimeter-precision measurement system for gate-slot inspection, underwater non-dispersible concrete technology (achieving compressive strengths up to C63.8), and underwater anti-corrosion coating systems.

The company delivers its services via direct enterprise field sales to large Chinese state-owned energy and infrastructure operators across hydropower (primary), nuclear power, offshore oil and gas, marine engineering, and municipal bridges. Its service portfolio includes underwater inspection and detection (visual, magnetic particle, ultrasonic, ACFM, CCTV), dredging, reinforcement and strengthening, crack treatment, construction and installation, topographic survey, and emergency salvage. Marquee engagements include gate-slot inspection and 23-ton chain-wheel salvage at Pubugou Hydropower Station (110m depth), ROV inspection at Three Gorges Dam bottom-outlet tunnels (84m depth, 14-day turnaround), and the international Malaysia Bakun and Cambodia Tatai hydropower projects executed via Chinese EPC partners. The company holds Class 2 Diving Operations Qualification from the China Diving and Salvaging Association (CDSA) and is certified as an underwater engineering service institution by six international ship classification societies (CCS, DNV, ABS, BV, ClassNK, KR), with ADCI membership since 2004 and active CDSA standing-director status.

The business model is project-based professional services revenue: contracts are won via competitive bidding on public SOE procurement notices, priced on a project-specific inquiry basis (not publicly disclosed), and delivered as multi-year contracts by mobile field teams deployed to client sites. The company co-authored national standards DL/T5251-2010, DL/T5315-2014, GB/T 37990-2019 and the reference book 'Underwater Reinforcement Technology for Reservoir Dams', embedding its methods into Chinese hydropower specifications. It has cumulatively completed 1,500+ major projects with zero safety accidents in high-altitude and deep-water operations, ranked #1 in revenue growth in the 2020 Qingdao High-Tech High-Growth Enterprise 50, and was named an industry benchmark enterprise in China's underwater engineering sector.
