Six ice-breaking LNG carriers caught up in the US sanctions against Cosco entities look set to return to normal trading after their owners were cleared from their "blocked person" status, according to Russian energy company Novatek.

"Yamal LNG has received notification from TC LNG Shipping, the joint-venture owning the Arc7 ice-class tankers, that joint-venture is no longer considered a 'Blocked Person' under the US Department of the Treasury’s Office of Foreign Asset Control rules," Novatek said.
