Gigantic structure of UFRJ transforms water, waves, and currents into an offshore laboratory used to test offshore technologies before platforms, ships, and submarine equipment face real conditions in the ocean, in operations that demand precision, safety, and advanced engineering.
In the Technological Park of UFRJ, at the University City in Rio de Janeiro, a structure of rare dimensions transforms still water into an environment capable of reproducing part of the forces found offshore.
Connected to Coppe/UFRJ, the oceanic tank of LabOceano holds 23 million liters of water and allows testing of oil platforms, ships, submarine equipment, and offshore systems before exposure to real ocean conditions.
According to UFRJ, the facility measures 40 meters in length, 30 meters in width, 15 meters in depth, and a central well of 25 meters, a dimension comparable to the height of an eight-story building.

Described by the university as the largest oceanic tank in the Americas, the laboratory was designed to simulate sea characteristics with waves, currents, and wind in naval and ocean engineering tests.
Largest oceanic tank in the Americas tests structures before the real sea
The scale is striking at first glance, but the main value of the structure lies in its ability to reduce risks before equipment and projects are taken to real operations in a maritime environment.
Scale models can be placed in the tank before a platform faces deep waters, a vessel is evaluated in a specific operation, or a submarine equipment is launched into the sea.
In practice, this process allows observing behaviors that would be too expensive, complex, or dangerous to test directly in the ocean, where variables are greater and control is limited.
According to UFRJ, wave generation is done by 75 plates of 1.80 meters in height, capable of creating controlled movements for different test scenarios.
The set not only produces surface undulations but also helps recreate navigation, installation, and operation situations where hulls, lines, floating structures, and equipment connected to the seabed interact with the movement of the water.
Each test seeks to show how the system responds when sea forces act simultaneously, revealing movements, efforts, and reactions that need to be understood before application on a real scale.
Waves, currents, and wind simulate pre-salt challenges
Instead of relying solely on calculations and digital simulations, the laboratory anticipates, on a reduced scale, situations that may occur in offshore exploration areas and ocean engineering operations.
UFRJ reports that the tank can simulate phenomena equivalent to those observed in water depths greater than 2,000 meters, a condition associated with Brazilian challenges in offshore oil and gas fields.
For a country with a large part of its reserves concentrated in the offshore environment, such infrastructure becomes strategic by bringing applied research, the energy industry, and technological development in naval engineering closer together.
Inside the tank, platform and vessel models do not function as decorative miniatures but as technical representations prepared to measure physical responses under controlled conditions.
Sensors, weight adjustments, measurement systems, and specific configurations help reproduce, within scale limitations, the expected behavior of real structures subjected to waves, currents, and wind.
The purpose is to evaluate movement, stability, hydrodynamic response, interaction with currents, and performance of components that may undergo repeated stresses during an offshore operation.
Submarine equipment and risers undergo scale testing
Another relevant application is in the study of flexible and rigid lines used in the connection between subsea wells and platforms, essential systems for the functioning of offshore production.
These components need to withstand movement, pressure, currents, and dynamic stresses over time, especially in operations conducted far from the coast and in deep-water areas.
In the laboratory, the movement of water and models allows for the evaluation of operational, installation, and safety scenarios without relying exclusively on field tests, where costs and risks increase.
The depth of the central well is one of the most important technical elements of the installation because it directly influences how lines, risers, and submarine equipment can be represented in the tests.
When a model is placed in the tank, the goal is not limited to verifying if it floats or withstands the wave, but to understand how the entire set responds to the combined forces of the sea.
This analysis helps engineers and researchers observe reactions of complex systems before larger structures are subjected to real operating conditions in the ocean environment.
Hydraulic pumps move large volumes of water
Besides the waves, LabOceano works with controlled currents in multiple directions, a necessary feature because the real sea rarely acts in a simple or predictable way.
Waves can come from one direction, currents can act in another, and the wind can alter the movement of a platform or vessel during an operation.
By reproducing part of this complexity, the tank allows for the observation of interactions that would not appear in static tests or isolated analyses, bringing the physical test closer to the conditions found outside the laboratory.
UFRJ also reports that the structure has six hydraulic pumps of a thousand horsepower each, responsible for moving large volumes of water and creating currents at different intensities and depths.
This capability brings the laboratory closer to a physical ocean simulator, where the water ceases to serve merely as a backdrop and starts to act as an active force on the tested models.
Naval engineering and autonomous systems also enter the tank
Although it has a strong connection with oil and gas, the use of the tank also extends to vessel hulls, autonomous systems, maneuver models, and technologies related to naval engineering.
The university describes applications in training and academic research, including the development of scaled-down boats and intelligent navigation systems used by students and researchers from Coppe/UFRJ.
Among the examples cited by UFRJ are hull models equipped with sensors, engines, and rudders, prepared to measure responses during different test conditions.
In these tests, the laboratory can evaluate how a vessel reacts to maneuvers, waves, currents, and balance changes, generating data that helps understand hydrodynamic performance before application in larger operations.
Bridge simulator reproduces maneuvers in Brazilian ports
In the same structure, UFRJ also maintains a bridge simulator developed with mathematical models in partnership with the Brazilian Navy, according to information released by the university.
The equipment reproduces complex maneuvers in Brazilian ports, including risk scenarios, intense sea currents, and engine failures, important situations for training and evaluation of operational decisions.
Although different from the tank itself, the simulator integrates the same logic of testing behaviors, responses, and procedures before they occur in real environments.
The UFRJ ocean tank brings together science, engineering, and industry around a common need: to understand the sea before platforms, vessels, and equipment are put into operation.
In offshore activities, small design changes can represent significant differences in safety, cost, and efficiency, especially when structures are subjected to repeated stress in deep-water areas.
For this reason, a scale test does not completely replace the ocean, but offers an intermediate step where problems can be identified without putting real structures at risk.
Laboratory in Rio reduces dependency on tests abroad
The presence of this infrastructure in Brazil also reduces the dependency on tests conducted outside the country, especially for companies and researchers operating in South America.
According to UFRJ, tests in European tanks can cost 15,000 to 20,000 dollars per day, not including team travel and other associated costs.
For national projects, a facility of this size in Rio de Janeiro expands access to experimental studies in ocean engineering and strengthens the local capacity to test offshore solutions.
From the outside, the tank may look like just a huge industrial pool, but its real function is to transform numbers, models, and physical forces into useful information for high-risk operations.
Inside, the structure tests platforms, ships, underwater robots, and equipment that work in some of the most challenging environments on the planet, using water itself as a testing machine.
If a structure in Rio can recreate waves, currents, and offshore conditions before billion-dollar equipment faces the real ocean, how many critical decisions in the offshore industry have first passed through this UFRJ “artificial sea”?
