Norway's Yara International has enjoyed a "strong" third quarter as profit and revenue rose.
The LPG carrier owner and fertiliser producer said its result was mainly driven by a stronger US dollar and acquisitions.
Net earnings to 30 September were NOK 4bn ($491m), against NOK 1.7bn in 2014.
Revenue was up at NOK 30.47bn from NOK 24.09bn.
Yara told TradeWinds it owns and operates three small CO2 vessels and a time-chartered fleet of between 15 and 18 LPG carriers, with an additional five LPG carriers on order.
