May 2006 saw the sale of Silja Line to the Estonian Tallink. The SuperSeaCats trafficking between Helsinki and Tallinn were not included in the sale as their purchase would have given Tallink a dominant market position on the route, which would have resulted in the competition regulators of Finland and Estonia not approving the sale. As a result, Sea Containers, after barely a year before announcing their intention to give up the ferry business completely, continued operating them under the SuperSeaCat brand. In late 2006 the land organisations of Tallink and Silja Line were reorganised in Finland so that Tallink Finland and Superfast Finland were merged into Oyj Silja Abp, which now took care of all Finnish operations of Tallink/Silja. Shortly afterwards Oyj Silja Abp was renamed into Tallink Silja Oy. Similarly the land organisations in Sweden became Tallink Silja AB.
