Just imagine, oil platforms the size of buildings, floating in the middle of the ocean, that can now be lighter and even more resistant! Sounds like science fiction? Well, that is exactly what a new Brazilian technology promises. Developed by the University of São Paulo (USP), this innovation has the potential to transform the oil industry by reducing billion-dollar costs in the construction of these platforms and even large projects like bridges.
Oil platforms and bridges are massive structures, weighing thousands of tons. In the case of platforms, this structure must withstand extreme conditions at sea, being resistant to both strong winds and waves as well as corrosion caused by the marine environment. This requires the use of large quantities of materials like steel, which significantly increases construction costs.
But now, thanks to topological optimization, a technique that allows simulating and finding the most efficient architecture for a construction, this reality can change. Renato Picelli, a professor at the Polytechnic School of USP, explains that the idea is to use this technique to create lighter oil platforms without compromising the necessary stiffness and resistance.
Cost and Material Reduction for Oil Platform Construction
The concept is simple, but the impact is enormous: by using topological optimization, engineers can reduce the amount of material needed for construction while maintaining structural stability. Instead of simply following a standard design, they simulate different configurations until they find the most efficient one. This results in structures that are not only lighter but also cheaper to build.

According to Picelli, this Brazilian technology can benefit not only the oil industry but also the construction of bridges and other large engineering projects. The reduction of materials and costs has the potential to revolutionize how these structures are built.
Offshore Structures and Brazil’s Role
Brazil, being a giant in underwater oil exploration, especially in the pre-salt area, has much to gain from this innovation. Floating oil platforms are essential for extracting the millions of barrels the country produces daily. In February 2024, for example, Brazil extracted 3.336 million barrels of oil per day, generating exports worth 2.7 billion dollars. This production volume is only possible thanks to the immense platforms operating at sea.
Offshore structures, built offshore, such as oil platforms and cargo transport ships, are crucial for this operation. And with USP’s new technology, these structures can be built even more efficiently and economically, keeping Brazil at the forefront of oil exploration.
Cutting-Edge Computing in Engineering
But how does this technology work? According to Professor Picelli, USP is developing a groundbreaking software that allows applying topological optimization in conjunction with fluid-structure interaction, something that does not yet exist in the market. “There are already commercial software to find the best structure, but not for fluid-structure interaction,” explains Picelli.
The development of this software places Brazilian scientific research in a prominent global position, allowing engineers to use this tool in the future to create even more advanced and efficient projects. “This is the science of business,” says the professor. “Creating methods that do not yet exist.”
The Revolution That Comes from Knowledge
This Brazilian technology is a great example of how academic research can transform reality outside universities. With the development of topological optimization for oil platforms and other structures, USP is at the forefront of a revolution in civil construction and naval engineering.
The future of these industries promises to be lighter, literally. With more efficient and economical structures, Brazil can continue as a power in oil exploration while saving billions in construction costs. And all of this, thanks to a technology that, soon, may be within reach of engineers around the world.
