For years, Ocean Sail Marine has been deeply engaged in the field of marine subsea equipment. We are a high-tech enterprise integrating R&D, manufacturing, sales and technical services. Our flagship product line is deep-water connectors. We focus on solving technical challenges of interconnection under harsh deep-sea conditions and advancing the domestic substitution and upgrading of marine deep-water connection equipment.

Founded in 2016, the company has steadily developed within the industry. We took the lead in launching durable safety plugs, establishing a new safety benchmark for the sector. In 2017, we focused on subsea connector development and built a large-scale domestic production base for subsea connectors. We later expanded our product portfolio with subsea floodlights, underwater monitoring systems, underwater detection equipment and other accessories to form a complete supporting product ecosystem for marine engineering.

In 2020, we established a strategic cooperation partnership with the Chinese Academy of Sciences. We collaborate with multiple universities to deepen industry-university-research integration and consolidate our R&D capabilities. In 2023, we successfully broke the long-term monopoly of international brands and realized full domestic substitution of core deep-water connectors. Our products are fully interchangeable with mainstream international brands including Subconn and Seacon, effectively addressing industry pain points such as high procurement costs and long lead times of imported products.

At present, the company boasts a professional R&D team of over 10 engineers and three modern manufacturing bases. We hold 8 patents and 1 software copyright, and have led or participated in formulating more than ten national and industrial standards. Our comprehensive qualification system includes authoritative certifications such as High-Tech Enterprise Certificate, Weapon Equipment Quality Management System Certification and industry-specific scientific & technical qualifications, earning wide recognition for our technical expertise and quality control standards.

Our deep-water connectors feature superior sealing performance, strong corrosion resistance, high pressure resistance, wide environmental adaptability and easy installation, suitable for all extreme deep-sea operating conditions. Our products are widely deployed in marine scientific research, offshore oil drilling, underwater robots, marine defense, environmental monitoring, aerospace and other sectors. We have long-term supplied clients including the Chinese Academy of Sciences, China State Shipbuilding Corporation, numerous research institutes, military manufacturing plants and key universities. Our consistent, reliable product quality has won high acclaim across the marine industry.
