The mystery around the sanctioned tanker Kairos (149,989 dwt) is continuing to grow as the vessel, which was attacked with a drone last week, is now reported drifting off Bulgaria. The Bulgarian authorities are seeking to assure the population that there is no immediate danger while they continue to monitor the vessel, which is now requesting an evacuation.

Kairos was the first of two tankers attacked by the Ukrainians off Turkey on November 28. The tanker, which is sanctioned by the West for its involvement in the Russian oil trade, was set on fire. Turkey reported it evacuated 25 crewmembers. At last report, Turkey said it was discussing towing operations with the vessel’s owners.

The ship, which was built in 2002, is reported to be owned by Chinese interests. It reports being registered in Gambia, but that is believed to be a false flag.

Midday on Friday, December 5, Bulgarian authorities observed a vessel entering their waters and tried to contact the ship, but received no response. They issued a warning to passing ships and were later able to confirm it was the tanker Kairos. In the early afternoon, they received a request from the 10 people aboard the ship for an evacuation. At that point, the ship was reported to be seven nautical miles from the Bulgarian coast and drifting.

The Bulgarian Maritime Administration was later advised that the crew had been able to drop the starboard anchor in an attempt to stop the tanker. They were working on releasing the port anchor as well. Residents were writing on social media that the ship was approximately 700 to 800 meters from shore and in danger of grounding.

 

 

The Bulgarian Navy dispatched a helicopter to survey the situation and is coordinating with the Border Police and maritime authorities. An emergency center has also been activated.

The sea is very rough with high waves and strong winds. The media reports are saying the crew aboard the tanker is in protective gear, but the authorities determined that it is too dangerous at night, with the current conditions, to attempt a rescue. 

It is unclear what happened to get the tanker from just north of Turkey across the Black Sea to a position off Ahtopol in southern Bulgaria. Unconfirmed reports are that the tanker had started a tow on December 3, bound for Tuzla, Turkey, but then turned toward Bulgaria. It is unclear where the towing vessel is and how the two ships became separated.

Bulgaria’s Maritime Administration Agency says the tanker is under constant surveillance, and they have been in contact with the crew on board


Shadow Tanker Mystery Continues as Crew Waits for New Tow off Bulgaria

Bulgarian authorities are still trying to understand the situation with the fire-damaged tanker Kairos, which washed up on their shores on Friday, December 5, during a storm in the Black Sea. The vessel was heavily damaged by an attack a week ago by the Ukrainians while it was underway near Turkey, and now it is on the Bulgarian shores with a skeleton crew aboard.

Contact has been established with the 10 people aboard the vessel, and after initially requesting an evacuation on Friday, they are now saying they will remain aboard the vessel and wait for a tow. The Bulgarian authorities report they attempted to question the crew but were told the captain and other senior officers had left the ship. The crew aboard says they are safe and have at least three days of food and water. 

An attempt to reach the ship on Saturday, December 6, with a launch from the border police was unsuccessful due to the high winds and rough seas, which also hampered the operations on Friday. Reports indicate the winds are over 29 knots (33.5 mph) and seas are at least three to five feet. Once the winds subside, the Bulgarian Border Police plan to board the tanker, likely using a helicopter. They will also be able to ferry additional supplies to the crew with a helicopter.

 

 

After drifting in the storm, the tanker came to rest approximately 700 to 800 meters (less than 1,000 yards) offshore near Ahtopol in southern Bulgaria. The Bulgarian Ministry of Transport reports “the reasons for the ship’s entry into Bulgaria’s territorial waters are yet to be clarified.”

The Turkish authorities said last week that they were working with the vessel’s representatives to arrange for a tow after putting out the fires on the tanker. The fire had been started after an explosion from a drone attack for which Ukraine took credit. The Bulgarians report the ship’s condition as “smoky,” while pictures showing the accommodation block and bridge are likely heavily fire-damaged.

It is unclear when or how the tanker and its tow detached on Friday. Some reports are saying the tug towing the tanker released it on Friday morning, about six miles south of Bulgaria, and headed back to Turkey.

 

 

The Kairos has been sanctioned by the West for its involvement in the Russian oil trade and was reported bound for Russia when it was attacked. Equasis reports the flag as “unknown,” while some reports have said Gambia, which was believed to be a false flag. The Bulgarian authorities are saying the vessel reported being registered in Benin.

Bulgarian officials said they have not made contact with the vessel’s owners and were not notified before the vessel entered the country’s waters. The crew did not respond to the initial calls from the Bulgarian maritime authorities as the tanker began to drift toward shore. Someone identifying as a representative of the Chinese owners contacted the maritime control center on Saturday, but for now, the Bulgarians report the incident remains under investigation.

The crew aboard the Kairos (149,989 dwt) was able to release the starboard anchor on Friday afternoon, and the reports said the anchor is so far holding the 274-meter (899-foot) vessel. The authorities emphasized that there is no crude oil cargo aboard, reducing the environmental danger. They expect the tanker will be towed to “a safe place” within the next few days.
