Sweden's Rederi AB Gotland has bought out partner Laurin Maritime's interest in three MR tankers.
The company said it had acquired 50% in each of the 46,000-dwt Calypso and Cavatina (both built 2010) and Corrido (built 2011), giving it 100% ownership.
The tanker and ferry company bought an initial 50% holding in the vessels in 2014 as it sought to lower its fleet age.
