One of the world's largest natural gas pipe-laying vessels, the CASTRONE, passed through the Bosphorus.
The Bahamas-flagged vessel set sail to participate in natural gas pipeline laying operations in Romania.
The 325-meter-long and 39-meter-wide CASTRONE entered the strait at 5:40 a.m. local time.
The vessel was escorted during the transit by the Nene Hatun, Turkey's first and largest emergency response, search-and-rescue, and firefighting ship, operated by the Directorate General of Coastal Safety.
Turkish authorities suspended maritime traffic in both directions in the Bosphorus during the vessel's passage.
After a closure lasting approximately two hours, the strait was reopened to maritime traffic.
