In order to expand on the position of the company group in the maritime sector of the international market, in 2003 Liebherr began to construct a production site for manufacturing maritime cranes in Rostock harbour. Construction began at the beginning of 2005 and continued steadily throughout the following years. The product line includes mobile harbour cranes, ship cranes and offshore cranes with up to 2000 tonnes of elevating force, which was used, among other things, for the expansion of offshore wind power plants. In 2007, a second production site was built in Lubmin, Greifswald, specialising in the production of crane jibs. The Rostock production site now covers an area of more than 437.000 m² and employs 1100 workers.
