The US has become the second largest source of global demand for dirty tanker exports as a result of higher oil production and shifts in trade patterns, according to Bimco.

This higher output from the US since 2013 has pushed crude tanker exports to 400,000 barrels per day (bpd) in 2016 to 3.5m bpd during the first eight months of this year, the international shipowners group said.
