The shipbuilding sector of Rio de Janeiro is one of the most important in the country, but it has already had two major historical crises: one in the 1980s, when it went bankrupt, and another that started in 2014, both due to the country's economic situation: between 2014 and 2016, the Brazilian shipbuilding industry lost 49% of its employed people. The drop of about 30 thousand vacancies was concentrated in the state of Rio de Janeiro, which closed around 23 thousand jobs in the same period. From 31.2 thousand employed in 2014, the number dropped to just 8 thousand in 2016. The gross real value of industrial production also fell 71%, from R $6.8 billion in 2014, to R $1.97 billion in 2016. However, at the end of 2019, the return of the pre-salt began to re-boost the naval sector: maintenance and repair activities pointed to increased demand for the coming years.
