The Australian Transport Safety Bureau identified that a relatively minor engineering error led to the grounding of the 59,000-dwt bulk carrier Dumun (built 2010) as it sailed from the coal exporting port of Gladstone in Queensland.

A threaded rod that transmitted the rudder position of the Dumun was too short and as a result only four millimetres was screwed into a connecting joint rather than about 20mm necessary to ensure a secure fitting.
