After becoming a Minister, Rousseff defended a new industrial policy from the government, ensuring that Petrobras' platforms had a minimum domestic content, what could generate 30 thousand new jobs in the country. She argued that it was unthinkable that a billion dollar building was not being made in Brazil. The bids for the P-51 and P-52 platforms were then the first in the country to require a minimum domestic content. The requirement was heavily criticized, on the grounds that it would increase the costs of Petrobras, but Rousseff defended the country's ability to produce ships and platforms, stating that the nationalization rates of the platforms, which varied between 15% and 18% rose to more than 60% after the requirement. Lula acknowledged that, from the perspective of the company, the costs did in fact go higher, but that Petrobras should not only target the immediate costs, but also the strengthening of national science and technologies. In 2008, the shipbuilding industry as a whole employed 40 thousand people, compared to 500 people in the mid-90s, in part because of the nationalization requirement. Brazil now has the sixth largest shipping industry in the world.
