The failure of three fenders precipitated a chain of events that ultimately resulted in the sinking of two Maersk anchor handlers off France last year, according to a report into the incident by the Danish Maritime Accident Investigation Board (DMAIB).

The Maersk Searcher and Maersk Shipper (both built 1999) capsized and sank in the Bay of Biscay on the night between 21 and 22 December 2016 while en-route to Turkey for scrapping.
