A massive salvage operation was planned to move the damaged tanker to a safe anchorage in Burgas Bay. Three tugboats from the Bulgarian Maritime Fleet were put to this task on December 15, 2025. A generator was also brought to the scene to restore power required for raising the anchor. The tanker was thoroughly inspected after it was towed to the safe location. At that time, investigators found no oil leaks or traces of hazardous substances in the nearby water. Inspections carried out later revealed that the tanker was damag
