The earlier operating concern was formed in autumn 1947 to manage Merivienti vessels, beginning a US liner service in 1948. The source also calls its original name O/Y Baltic Chartering, changed to O/Y Finnlines in 1953 and FG-Shipping on 6 June 1989. Enso-Gutzeit owned part or all of Finnlines before selling 75% in 1982. Vessels in Finncarriers traffic passed to EFFOA and Neste, and the Finncarriers interest was relinquished to EFFOA. Atlantic Gulf Service operated with Swedish America Line; many ship names began with Finn.
