On July 28, 2018, the crude oil tanker was heading for Midia, Romania, when she suffered an engine failure. Without power the vessel went adrift. Authorities were alerted and three tugs were dispatched to the scene. The tugs took the tanker under tow through the Bosphorus and on August 3, Nissos Therassia, had been safely towed through the strait, causing a complete traffic interruption during many hours.
The tugs Kurtarma 7 and Kurtarma 8 are seen at the stern of the Nissos Therassia.
