Cubage (74x50 cm) In the 1840s, the Chaigneau-Bichon shipyards were Lormont's biggest employers, with almost 410 employees. In 1852, Jean Bichon put an end to the alliance with Chaigneau and became independent, leaving the ancestral site and setting up on a 10-hectare plot of land on the right bank of the Garonne. His two sons succeeded him at the head of the company from 1861 onwards. On January 9, 1856, a decree granted shipbuilder Chaigneau authorization to build a careening dock near Bacalan. Work began, but was abandoned. Another decree on May 27, 1857 granted the same rights to the Bichon shipyards, but nothing was actually done.
