History of the Shipyard

Legacy shipyards with advanced facilities, with operations in the ship repair industry since 1928

San Giorgio del Porto is a Genoa-based shipyard that was founded in 1928 as a ship maintenance workshop and foundry by Ferdinando Garrè, who went by the same name as the current CEO.

Due to bombing that destroyed the workshops during World War II, the shipyard was forced to relocate to northern Italy, where it engaged in the production of agricultural equipment. Only after the end of the war, was SGdP able to return to Genoa, where the shipyard expanded its range of activities over the years to include vessel reconversion.

While in the early years, the shipyard focused primarily on routine maintenance and repair operations (engaging in three main types of activity: mechanical, metal carpentry, and structural engineering), a glorious decade began after the war was over, in the 1950s.

SGdP used to specialize in propeller drive shafts and frequently had to work without tools that could substitute human efforts. Thus, it was often necessary to move huge weights by hand, or at best using hoists.

This is a time when the shipyard was involved in an area that up until then was little known, i.e. the transformation of vessels. In this way, the company worked at a steady pace until the 1980s.

After the shipbuilding industry entered a crisis, the company experienced evolution as the range of operations changed and became more challenging. For this reason, SGdP decided to focus on advanced engineering, as well as safety and environmental issues, as well as new business segments.

Thanks to 90 years of experience and a staff consisting of naval architects, mechanical engineers, a highly skilled workforce and emergency response teams trained by specialized technicians, San Giorgio del Porto is nowadays a top-notch Mediterranean shipyard capable of assisting any type of vessel (cruiser, offshore, chemical and gas carrier, military ship, etc.) all over the world.
