The new contract places a highly complex vessel at the center of Petrobras’ offshore strategy, brings construction to the Santa Catarina shipyard, and transforms submarine support vessels into key assets for inspection, maintenance, and repair in deep waters for the coming years.
According to the nd+ portal, what makes the news significant is not just the value. The future vessels will be used for submarine inspection, maintenance, and repair in deep waters, will be approximately 98 meters long, have capacity for up to 58 people on board, submarine cranes, and two surface ROVs to operate remotely on the seabed. Furthermore, the new fleet was presented as a “green vessel,” with a hybrid propulsion system powered by ethanol, diesel, and batteries.
The billion-dollar contract placed Santa Catarina at the center of a strategic Petrobras operation
The signing announced by DOF Group repositions the Navship shipyard, in Navegantes, as part of a high-value industrial chain linked to offshore oil and gas. Instead of a one-off order, it is a long-term package, with local construction and operation focused on a critical activity for Petrobras in complex submarine environments.

This detail changes the scope of the agenda. It’s not just about manufacturing a vessel or expanding an industrial portfolio. The agreement involves four specialized vessels, each linked to 12-year contracts, within a logic of lasting infrastructure to support operations on the seabed. This gives the project a weight that goes beyond shipbuilding and connects it directly to Petrobras’ future operational capacity.
The R$ 11 billion helps to show the true scale of the order
The total value of the contracts approaches US$ 2 billion, equivalent to over R$ 11 billion at the current exchange rate. In a sector accustomed to large-scale projects, this amount already places the operation on another level, mainly because it combines the construction of new units, long-term operation, and performance in highly demanding submarine services.
The time horizon also stands out. Each vessel will have a 12-year contract, indicating a long-term commitment to a new and specialized fleet. The forecast is that the first two vessels will be delivered within four years after the official signing of the contracts, while the start of operations is projected for 2030. In other words, the investment not only responds to immediate demand but prepares a support structure that should last through the next decade.
The most curious detail lies in the type of vessel that will be built to work on the seabed
The most surprising part of the story lies in the technical profile of these vessels. The new RSVs, ROV support vessels, were not designed for conventional transport or simple surface support. They will be used in complex submarine missions, focusing on inspection, maintenance, and remote repair in deep environments, where operational precision makes a difference.
These vessels will be approximately 98 meters long, with accommodation for up to 58 people on board, submarine cranes, and two remotely operated vehicles capable of operating on the seabed. This setup transforms the vessel into a kind of mobile base for submarine operations. This is precisely where the news gains significance: the contract does not revolve around a common vessel, but a highly specialized maritime structure, designed to operate where the sea ceases to be a backdrop and becomes an extreme technical work environment.
The hybrid fleet expands the technological and environmental significance of the offshore operation
Another point that differentiates the project is DOF’s proposal for vessels considered “green”. According to the company, the ships will have a hybrid propulsion system powered by ethanol, diesel, and batteries, focusing on reducing emissions during offshore operations. In a segment traditionally associated with high fuel consumption and heavy logistics, this detail adds an important technological layer to the order.
This matters because shipbuilding focused on oil now also carries the pressure for environmental efficiency. Even within a chain linked to offshore exploration, the market seeks more modern vessels, with lower operational impact and greater adherence to future emission requirements. In this context, Santa Catarina enters not only as a manufacturing hub but as part of a project that tries to combine naval industry, submarine support, and technological renewal.
The agreement reinforces Brazil’s importance on the global offshore oil map
Commenting on the contracts, DOF CEO, Mons S. Aase, stated that the agreement reinforces Brazil’s strategic position in the global offshore oil and gas market. The statement fits the project’s scale. When an international company links new constructions, long-term operation, and financing aimed at local development, the move signals confidence in the country as a relevant center for this industry.
Brazil’s weight in this scenario comes not only from oil production but also from the need to maintain sophisticated infrastructure to operate in deep waters. The more complex submarine operations are, the greater the demand tends to be for specialized vessels, remote systems, constant maintenance, and shipyards capable of delivering high-standard technical vessels. It is at this point that the contract ceases to be merely regional and begins to engage with the global competition for offshore capacity.
What this project reveals about the future of shipbuilding and deepwater operations
The order for the four vessels in Navegantes reveals a clear trend: the offshore sector will continue to demand increasingly specialized vessels, integrated with remote technology and prepared to operate in difficult environments. The future of deepwater operations depends not only on platforms and production but also on the fleet that supports inspection, repair, and maintenance on the seabed.
