When the shipyard was founded, the number of workers was around 40-50, all of whom were foreigners (English, Italian, German, Dutch, and Croatian), as this type of work did not have precedents in Hungary. A significant number of these workers were housed in Óbuda. Thanks to the factory expansion, by the mid-1840s more than 300 people were working in the plant, which number reached 1,000 by the middle of the century.
The DDSG officials had a company pension fund in operation since 1846. The shipyard management did a lot to improve the circumstances of the workers: they developed the infrastructure of the industrial facilities, and a grocer’s was set up in situ. In 1856, foremen's apartments were built on the factory premises. By the second half of the 1800s, more and more Hungarian workers, mainly from Óbuda, were able to find employment in the shipyard, a process that accelerated over the years.
