COOEC is a core offshore engineering subsidiary of CNOOC, responsible for subsea construction, installation, and field maintenance across China’s offshore energy industry. The company operates a large fleet of work-class and observation-class ROVs, which support pipeline surveys, riser inspections, subsea infrastructure assessment, and deepwater construction tasks. These vehicles are routinely integrated into engineering campaigns in the South China Sea, Bohai Bay, and East China Sea. COOEC uses UUVs to reduce operational risks and improve consistency in repetitive subsea inspection tasks. The company also participates in Chinese research initiatives exploring autonomous underwater navigation and long-duration subsea monitoring systems. Its UUV operations extend to select overseas EPC projects in Southeast Asia and West Africa, reflecting its growing international project footprint. COOEC’s UUV activities are primarily functional, focusing on operational efficiency, asset reliability, and safe subsea intervention.

Mitsubishi Heavy Industries Ltd. is a major engineering and defense systems manufacturer in Japan and maintains a structured program for developing autonomous and remotely operated underwater platforms. The company produces AUVs for seabed mapping, undersea surveillance, and oceanographic monitoring, alongside ROVs for inspection and utility tasks. These platforms leverage MHI’s capabilities in marine systems engineering, robotics, and propulsion technologies. The company’s UUVs support Japanese national priorities such as maritime domain awareness, seabed resource mapping, and monitoring of undersea infrastructure. The company also contributes to defense-led research focused on long-endurance autonomous patrol and detection capabilities. Operational deployments are concentrated within Japanese territorial waters, including the Philippine Sea and Western Pacific zones. It participates in collaborative technology programs with research institutes and government laboratories to advance the autonomy and durability of UUVs. This also reflects Japan’s growing emphasis on underwater situational awareness and environmental monitoring.

JOHNAN Corporation develops compact ROV systems for coastal inspection, aquaculture operations, fisheries research, and shallow-water scientific studies. The company focuses on designing maneuverable platforms suited for confined spaces such as fish cages, harbor structures, and municipal underwater assets. Its systems are used by fisheries cooperatives, aquaculture operators, local governments, and university research labs across Japan. JOHNAN works on improving vehicle stability, operator control interfaces, and payload integration through collaborations with academic institutions. The company’s ROVs are also used for routine maintenance checks of seawalls, aquaculture nets, and submerged facilities. In addition to its domestic market, the company is gradually expanding into Southeast Asia, where aquaculture expansion is creating demand for compact underwater observation systems.

CHASING Innovation is a Chinese producer of small and mid-range ROVs commonly used for general inspection, aquaculture monitoring, underwater observation, and public safety operations. Its systems are designed for short- to medium-duration missions, offering portability for deployments in reservoirs, coastal areas, and underwater infrastructure sites. CHASING’s ROVs are widely adopted by municipal agencies, aquaculture farms, commercial divers, and marine service providers. The company maintains a broad distribution network across the Asia Pacific, including China, Southeast Asia, South Korea, and Australia. It focuses on improving imaging quality, integration of optional mechanical tools, and enhancing control stability for varying underwater conditions. CHASING’s platforms are used in aquaculture net inspection, bridge foundation checks, underwater search tasks, and basic structural assessments, among others.

Total Marine Technology (TMT) is an Australian subsea engineering company that is involved in the design, manufacturing, and operation of work-class and observation-class ROV systems. The company caters to offshore drilling, subsea intervention, structural inspection, and deepwater survey operations across the Indian Ocean and broader Asia Pacific region. It is engaged in ROV manufacturing, refurbishment, and engineering support from its facilities in Australia. Its vehicles are deployed extensively in Australia’s offshore LNG fields and have been used on projects in Malaysia, Indonesia, and other Southeast Asian offshore zones. Total Marine Technology collaborates with research organizations and defense entities on selected technology development initiatives related to underwater systems. The company also provides operational personnel and mission support for contractors conducting subsea engineering activities.
