Several Factors Contribute To Grounding Of Norvantes
The displacement of a critical channel marker was a trigger that bought a number of causal factors into play, all of
which contributed to the grounding of the Singapore cattle carrier Norvantes, according to a report released today by
the Marine Incident Investigation Unit of the Australian Transport Safety Bureau.
The report states that the ship was grounded in an approach channel near Karumba, Queensland on 19 November.
The ship was refloated within 24 hours and after an inspection of the hull and an inspection of the cattle on board by
a vet, the ship was permitted to continue its voyage to the Philippines. Nobody was hurt, none of the cattle were
injured and no pollution resulted from the grounding.
The displaced channel mark should have indicated an alteration of course position for the pilot. However, when he
realised that it was out of position he estimated his turning point and turned too early.
The report also identifies factors of poor bridge resource management, limited visibility from the bridge, navigation
lights lost in the "black scatter" of a shore construction project, an inappropriate chart scale and fatigue as being
among other factors contributing to the grounding.
