World’s Deepest Marine Test Basin
Sea test tanks are facilities used for underwater testing and research, simulating the behavior of ships, offshore platforms, and other marine structures under specific conditions in a controlled environment.
Also known as towing tanks or mock-ups, these facilities allow experts to test specific ship or structure designs and improve their performance while enhancing safety.
National Institute of Marine Science and Technology (NMRI) in Tokyo, Japan, operates the world’s deepest sea test tank, which simulates the immense pressures of the deep ocean.
Completed in June 2002, the facility was designed to meet the research and development needs of deep-sea technologies.
Marine Test Basin
The facility consists of a circular tank with a diameter of 14 meters and a depth of 5 meters. It also includes a smaller, deeper pit with a diameter of 6 meters and a depth of 30 meters, for a total depth of 35 meters, or 114.8 feet. This world’s deepest ocean test tank is equipped with absorbing wave generators, current generators, and an advanced 3D underwater measurement system. Its movable bottom allows for depth variations from 5 to 35 meters.
This facility enables the development and testing of equipment designed to operate in harsh water conditions.

It is used to test deepwater oil and gas extraction technologies and systems for mining mineral resources on the seabed within Japan’s exclusive economic zone.
It also facilitates the development of equipment capable of operating at depths of thousands of meters.
It is also used to test the functionality and durability of manned and unmanned underwater vehicles (ROVs) before deployment at sea. This includes testing components, control mechanisms, and power systems under simulated conditions.
David W. Taylor Model Basin
The David W. Taylor Model Basin in Carderock, Maryland, is another renowned marine test basin. Known as the world’s largest marine test basin, it is a large facility operated by the United States Navy.
Constructed in 1939, the facility has facilitated numerous advances in naval architecture and engineering, and has facilitated the development of numerous warships, from submarines to aircraft carriers.
The facility also facilitates research that influences international naval design standards. It consists of several docks designed for specific types of testing.
The deep dock is used to test large ship models, the shallow dock is used to simulate coastal environments, and the high-speed dock is used to test high-speed vessels.
The facility is equipped with a variety of equipment to create and measure various operating conditions, including wave generators, tugboats, and data collection systems.
Aalto Ice and Wave Reservoir
This marine test dock in Espoo, Finland, is the world’s largest inland ice reservoir by area. It serves as a key center for marine and Arctic technology research, enabling the study of the complex interactions between ships, marine structures, and ice.
The ice reservoir is a 40 x 40 meter square tank with a surface area of 1,600 square meters, enabling complex experiments that would be impossible in narrow tanks.
It is 2.8 meters deep and equipped with a cooling system to simulate real sea ice.
The ice wave reservoir is equipped with a wave generator capable of generating regular and irregular waves, allowing researchers to study wave-ice interactions and their effects on ships and other structures.
The reservoir supports academic and industrial partners by providing navigational testing services in the Arctic and other cold and hazardous waters.
It is specifically designed to test the strength, propulsion, and maneuverability of ships navigating through ice under simulated conditions. It is particularly useful for studying large turning radii and dangerous or complex maneuvers.
Researchers also use it to study the properties of ice and how it breaks under different loads. It also facilitates the study of the effects of ice on fixed structures, such as offshore platforms and wind turbines.
Using a combined ice-making system and wave generator, experts have studied the effects of waves on icebergs.
