Vuosaari shipyard was merged with Wärtsilä in 1986 to form Wärtsilä Marine of which Valmet owned 30%. After the downturn in shipbuilding in the mid-1980s, the company decided to close the Vuosaari shipyard on 13 January 1987 and move the shipbuilding to Helsinki Shipyard in Hietalahti. In 1987–1991 various shipping companies rented the old shipyard from Wärtsilä for routine dockings. The cranes were sold in 1991, two to Germany and two to Rauma shipyard. Several ship repair companies operated in and around the old dry dock until 2004, when the construction of the new harbour cut the connection to the sea.
