Navigator Holdings is denying any wrongdoing after three of its ships appeared on a list of vessels that worked to deliver petroleum to Syria's ruling government in violation of various international sanctions.

In a statement to TradeWinds Wednesday morning, the London-based LPG carrier owner said they were "unaware of any allegation or charges" from the US Treasury Department's Office of Foreign Asset Control (OFAC) in relation to alleged ship-to-ship transfers of petroleum.
