TT-Line GmbH & Co. KG (TT-Line) is a German ferry operator providing RoPax services across the Baltic Sea. Founded in 1962 and headquartered in Lübeck-Travemünde, the company operates routes connecting Germany (Travemünde, Rostock) with Sweden (Trelleborg), Poland (Świnoujście), and Lithuania (Klaipėda). Its services combine passenger transport with rolling freight logistics, including trailers, containers on chassis, and project cargo.
For the chemical industry, TT-Line supports European supply chains by offering short-sea RoRo links that complement road and rail, including the transport of hazardous goods in line with IMDG/ADR regulations. The fleet includes modern ferries with LNG-capable propulsion and shore-power readiness, reflecting sectoral moves toward lower-emission maritime transport and compliance with evolving EU and IMO standards.
