Underwater Connectors Market Report 2026

The underwater connectors market size has grown strongly in recent years. It will grow from $1.85 billion in 2025 to $1.99 billion in 2026 at a compound annual growth rate (CAGR) of 7.3%. The growth in the historic period can be attributed to growth in marine exploration activities, reliance on mechanically sealed connectors, increasing offshore oil and gas operations, adoption in military subsea communication systems, expansion of underwater research programs.

The underwater connectors market size is expected to see strong growth in the next few years. It will grow to $2.68 billion in 2030 at a compound annual growth rate (CAGR) of 7.8%. The growth in the forecast period can be attributed to rising use of ocean drones and rov systems, increasing deep-sea data transmission needs, development of high-durability corrosion-resistant connectors, expansion of offshore renewable energy projects, growing demand for high-reliability underwater power and signal links. Major trends in the forecast period include deployment of smart subsea connectivity solutions, expansion of automated underwater robotic systems, integration of IoT-enabled marine communication networks, advancement of digitally monitored deep-sea infrastructure, development of AI-enhanced subsea equipment diagnostics.

The anticipated increase in oil and gas exploration activities is poised to drive the growth of the underwater connectors market. Oil and gas exploration involves the search for areas rich in oil and natural gas resources, suitable for drilling and extraction sites, as well as reserves of these valuable commodities. With the expansion of oil and gas exploration efforts, there is a growing demand for underwater connectors to establish and maintain efficient and reliable connections between underwater wells, pipelines, and processing facilities. For instance, in December 2024, according to the Energy Information Administration, a US-based government agency, in December 2022, U.S. oil production - including crude oil and lease condensate - averaged 12.2 million barrels per day (b/d), while gross withdrawals of natural gas averaged 121.1 billion cubic feet per day (Bcf/d). Both oil and natural gas output rose in 2023, with oil production averaging 13.3 million b/d and natural gas gross withdrawals reaching 128.8 Bcf/d in December 2023. Consequently, the surge in oil and gas exploration activities is a significant factor propelling the growth of the underwater connectors market.

Leading companies in the underwater connectors market are concentrating on innovative solutions, such as hybrid connectors, to enhance the versatility and efficiency of subsea connections. These hybrid connectors facilitate seamless integration of electrical, optical, and data communication capabilities while minimizing space requirements and boosting performance in challenging underwater environments. Specifically designed for confined marine spaces, the hybrid connector is a compact device that consolidates power, data, and communication into a single unit, featuring dual optical passes and four electrical contacts for improved versatility. For example, in January 2024, MacArtney Group, a Denmark-based company that provides underwater technology products, launched its Hybrid connector, a compact addition to its well-known TrustLink™ Metal Shell series. The TrustLink Metal Shell (MS) design emphasizes reliability in a high-density connector, tackling the challenges posed by harsh marine environments with limited space.

In March 2025, Keppel Ltd., a Singapore-based asset management and infrastructure company, through its Keppel Infrastructure Fund (KIF) and a co-investor, acquired Global Marine Group (GMG) from investment affiliates of J.F. Lehman & Company for an undisclosed amount. With this acquisition, Keppel Ltd. aims to broaden its presence in the rapidly expanding subsea cable sector, strengthen its digital infrastructure and connectivity ecosystem, and capitalize on the increasing demand for subsea cable maintenance and installation services while supporting long-term sustainable growth and investment returns. Global Marine Group (GMG) is a UK-based subsea engineering company that operates a fleet of specialized vessels delivering mission-critical maintenance and installation services for subsea fiber optic cable networks.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have impacted the underwater connectors market by increasing costs for imported metals, elastomers, electronic housings, and precision-machined components required for subsea equipment. Marine, oil and gas, and defense sectors in North America and Europe experience the strongest effects due to reliance on global supply networks. However, tariffs are also stimulating investment in regional subsea connector manufacturing, promoting technological innovation in corrosion-resistant materials, and enhancing long-term supply chain stability for deep-sea infrastructure.

Underwater connectors, also referred to as wet-mate connectors or marine connectors, are specifically designed to couple or uncouple in wet environments while enduring harsh conditions such as seawater corrosion, high pressure, vibration, and shock. They find applications in diverse underwater scenarios, including military submarine electronics, ocean drones, buoys, miniature Remotely Operated Vehicles (ROVs), and commercial diving apparatus.

Various types of underwater connectors include fluid-filled underwater mateable connectors, inductive coupling, rigid shells or bulkheads, and rubber-molded connectors. Fluid-filled underwater mateable connectors employ a design featuring a chamber filled with dielectric fluid (such as oil) to protect the contacts from water. These connectors cater to a wide array of connections, including electrical, optical fiber, and hybrid connections. They serve various industries such as IT and telecom, marine, military and defense, oil and gas, among others.North America was the largest region in the underwater connectors market in 2025.
