Underwater connectors are critical and complex deep-sea engineering equipment components. For reference, underwater connectors are also called sub-sea connectors and marine connectors designed to work in extreme environments, including vibration, pressure, shock, and corrosive seawater. Efficient technical equipment is critical for the effective deep-sea exploration and usage of this vast blue ecological system. Many manned and unmanned underwater vehicles have been developed, requiring underwater connectors, such as remotely operated vehicles, autonomous underwater vehicles, human-occupied vehicles, and hybrid ROV and AUV.

Many undersea observatories have been built, such as the Hawaii Undersea Geo-Observatory (HUGO) and the Astronomy with a Neutrino Telescope and Abyss Environmental Research (ANTARES) project. Various kinds of marine engineering equipment have also been deployed to exploit oil and gas, as well as offshore renewable energy (ORE) farms.


Marine Sector Faced Unmatched Challenges Due to Ongoing COVID-19 Pandemic

The global market has witnessed a significant decline due to the COVID-19 impact. Disruptions in the supply chain, reduced defense budget, and a slowdown in the economy hampered the market growth during the pandemic.

  • According to UNCTAD, global maritime transport plunged by 4.1% in 2020 due to unexpected disruption from the COVID-19 pandemic. Due to less business, the disruption mainly hampered the supply chain, shipping network, trade volumes, and port.

  • Investments in the shipbuilding sectors were declining during the pandemic. The decline in shipbuilding services for different offshore services, maritime trade, maritime export, and others has impacted the demand for autonomous underwater vehicles. This development has ultimately impacted the underwater connectors market growth.

Advanced Subsea System for Commercial and Military Applications to Drive Market Growth

Rise in demand for underwater connectors has showcased the deployment of subsea platforms and the high adoption rate of the sub-sea equipment for applications, such as submarine communication cables, oceanography, deep-sea mining. The rubber molded connectors are widely used in the market. In 2019, Hydro Group launched a wide range of underwater rubber molded connectors capable of catering to a range of sizes, combinations, and voltages and have specifications, such as ruggedness performance, quick installation, cost-effectivity.

With the high demand for subsea equipment and platforms in military and telecommunications, the market players emphasize on increasing the production of inductive coupling underwater connectors for data transfer applications.


Increased Submarine Communication Cables and Defense Expenditure owing to Naval Modernization to Drive Market Growth

Over the last decade, the navies worldwide have emphasized the utility of manned and unmanned underwater vehicles, which has influenced the development of advanced communication and detection equipment. This impact has driven the need to modernize the existing subsurface fleet and acquire manned and unmanned underwater platforms for border protection and Intelligence, Surveillance, and Reconnaissance (ISR) activities.

This development has influenced the rise in defense expenditure by the governments worldwide to invest in naval capability enhancement. The U.S. Navy has been developing the Orca Class of XLUUV for its unmanned underwater capabilities. Also, it has been involved in developing the next-generation Columbia Class submarines, which will help in the increment in market growth during the forecast period.

Accelerating Deep-Sea Explorations, Mining, and Oil & Gas Activities to Boost Market Growth

AUV's major operations include bathymetry, acoustic imagery, optical imagery, sub-bottom profiling, water column characterization, ocean current profile with tides, temperature profile, salinity profiles, water clarity, and bio-luminescence. Several ocean surveys require a large amount of sampling, data profiles, and a longer period for precise evaluation, which are expensive in various countries. The AUV systems are fully equipped with numerous sensors, systems, and tools which gather extensive information in less time. These factors are projected to fuel demand for AUV systems in forthcoming years.

For instance, in October 2021, India’s National Institute of Ocean Technology launched a deep-sea exploration mission named Samudrayaan Mission to develop, test, and manufacture underwater deep-sea exploration vessels.


High Installation and Maintenance Cost and Limitation of the Certain Underwater Connectors to Restrict the Market Growth

Despite the high underwater connector demand, rigid shell underwater connectors have certain limitations, such as pressure variation between their inner and outer shell, highly prone to corrosion. These factors influence the overall performance of the connectors in subsea applications. Hence, it leads to high installation and maintenance costs. The underwater platforms which are utilizing rigid shell connectors may face major setbacks and operational performance issues.
