Norway's Klaveness Combination Carriers (KCC) has logged earnings of up to four times standard tankers in the third quarter.
The company said the flexible fleet of ships carrying both wet and dry cargoes showed "significantly improved" results as Ebitda rose 17% from the second quarter to reach $17.9m.
The performance was mainly driven by a strong dry bulk market and increased fleet capacity following completion of KCC's newbuilding programme, said chief executive Engebret Dahm.
