High-quality, well-matched marine instrument collaboration—In partnership with the Institute of Marine Instruments and Meters, Shandong Academy of Sciences

CASE

Brand Case

Leveraging years of technological expertise, Haige Wei has built a comprehensive product ecosystem covering underwater signal transmission, environmental sensing, and lighting protection.

The Institute of Ocean Instruments and Meters at the Shandong Academy of Sciences is a leading domestic institution dedicated to the research and development of marine instruments. It focuses on the R&D and industrialization of instruments and equipment for applications such as marine environmental monitoring and marine resource exploration. The institute’s new deep-sea monitoring instrument project places high demands on the reliability, environmental adaptability, and data transmission stability of its supporting electronic devices. Thanks to its expertise in core technologies such as watertight connections and electronic sealing, Haigewei Electronics has successfully been selected as a supplier supporting this project.

Frontier Technology R&D Collaboration between Universities—Background of Cooperation with Northwestern Polytechnical University

Northwestern Polytechnical University boasts advanced research capabilities in fields such as aerospace and marine engineering, placing it among the leading institutions in China. The university’s research project, “Navigation and Observation System for Deep-Sea Intelligent Vehicles,” is dedicated to overcoming key technological bottlenecks in deep-sea intelligent equipment and places high demands on the miniaturization, high precision, and low power consumption of associated electronic devices. Thanks to its innovative technological prowess in products such as underwater cameras and underwater lighting fixtures, Haigewei Electronics has become a core supplier supporting this project.

Military Equipment and Related Support Cooperation —— With the 760th Research Institute of China Shipbuilding Industry Corporation (CSSC 760)

The 760th Research Institute of CSSC focuses on scientific research and equipment development in fields such as ship and marine rescue, and underwater engineering. It adheres to stringent quality and performance standards, particularly in the area of military-related equipment. In a certain underwater protective equipment R&D project, there is an urgent need for electronic components with high sealing performance and excellent resistance to harsh environmental conditions, to ensure stable operation in scenarios such as deep-sea rescue and national defense protection. Leveraging its qualifications as a qualified supplier for military products and its core technological strengths in underwater electronic devices, Haigewei Electronics has successfully become the institute’s partner for military-related supporting equipment after undergoing multiple rounds of rigorous product testing and qualification audits.

China University of Petroleum Offshore Oil and Gas Exploration Equipment Supporting Project

In the field of offshore oil and gas exploration, the research and practical work conducted by China University of Petroleum rely on stable and reliable underwater electronic equipment to carry out data acquisition and detection tasks. In response to the unique characteristics of the offshore oil and gas exploration environment, Haigewei Electronics has provided the university with customized products such as underwater lighting fixtures, watertight connectors, and electronic sealed housings. The underwater lighting fixtures feature specially designed light sources tailored to meet operational requirements in the dim, deep-sea environment; while the watertight connectors and electronic sealed housings boast exceptional corrosion resistance and high-pressure tolerance, enabling them to withstand the complex operating conditions encountered in offshore oil and gas exploration. The application of these products has reliably ensured the stable operation of the university’s offshore oil and gas exploration equipment, helping it obtain accurate exploration data. Building on this successful collaboration, both parties have also reached an intention for long-term cooperation in the field of supporting electronic equipment for marine resource development.
