On 25 February 2016, the bulk carrier New Katerina ran aground in the canal while traveling from Ukraine to Qingdao. It was refloated after twelve days; traffic in the canal was not affected during this period.[11] On 28 April 2016, the container ship MSC Fabiola ran aground at Great Bitter Lake after experiencing engine problems, forcing canal officials to temporarily suspend all northbound convoys and stop all southbound convoys in the canal. MSC Fabiola was refloated on 30 April, and continued through the canal.[12][13] On 17 July 2018, the container ship Aeneas ran aground in the canal, resulting in a collision involving the three bulkers behind it: Sakizaya Kalon, Panamax Alexander, and Osios David.[14][15] Most of these incidents had a relatively minor effect on traffic in the Suez Canal.
