The salvage operation for the oil tanker MT Sounion is facing a setback as private companies involved in the rescue efforts have determined that conditions are not suitable for towing the vessel, prompting a search for alternative solutions, gCaptain reports. The Greek-registered Sounion, carrying approximately 1 million barrels of crude oil, presents a significant environmental threat after it was set on fire by Yemen’s Houthi militants on August 23. Several fires continue to burn on the vessel.
