Vuosaari shipyard was a shipyard located in the district of Vuosaari in Helsinki, Finland. Built by the Finnish state-owned company Valmet Oy in the early 1970s, the shipyard delivered 33 newbuildings and participated in building around 100 other vessels before it was closed in 1987 following the bankruptcy of Wärtsilä Marine. Later, the longest dry dock in Finland was used by various ship repair companies until the construction of the new Vuosaari harbour cut the connection to the sea in 2004. Despite various plans to re-use the old dry dock, now located inside the harbour perimeter, it remained without use until the basin was backfilled in 2015–2016.
