A Greek suezmax tanker needed a tow on Sunday after breaking down in the Suez Canal.
The Suez Canal Authority (SCA) said the 159,000-dwt Seavigour (built 2016) briefly disrupted traffic after it suffered engine failure.
Photos showed two tugs moving the million-barrel ship from a single shipping lane in the vital waterway.
SCA chairman and managing director Osama Rabie said in a statement that traffic in both directions had resumed as normal.
The tanker was heading from Russia to China, the authority added.
The last port call shown on AIS was Fos Sur Mer in France on 3 May.
An update from Sunday showed the Seavigour stopped near Port Said.
The vessel lost power at the 12km mark, SCA spokesperson George Safwat told Sky News.
The ship stopped in a single-lane section and was towed away to a double-lane stretch at the 17km mark.
The breakdown disrupted eight other ships behind the 274-metre Seavigour.
The vessel is operated by Thenamaris, which said it does not comment on commercial matters.
The Malta-flag tanker has no port state control detentions on its record.
Supramax and LR1 among recent Canal casualties
On 25 May, a Chinese-controlled supramax grounded in the Suez Canal but was swiftly freed by the SCA, Leth Agencies reported.
The 57,000-dwt Xin Hai Tong 23 (built 2010) got stuck at kilometre 159, causing delays to four northbound vessels.
It was refloated within a few hours.
And in April, the 73,000-dwt Torm LR1 tanker Torm Sara (built 2003) got stuck in the Great Bitter Lake.
Again, a refloating attempt was successful within a few hours.
The spotlight on incidents in the canal has been fiercer than ever before since the dramatic grounding two years ago of the 20,388-teu Ever Given (built 2018), which brought a large part of world trade to a standstill for almost a week.
The boxship grounded on 23 March 2021, blocking the canal for six days and becoming front-page news around the world.
