Significant safety issue
There was no effective fatigue management system in place on board Shen Neng 1 to ensure that the bridge watchkeeper was fit to stand a navigational watch after the loading in Gladstone.
Response from Tosco Keymax International
The ATSB has been advised by Tosco Keymax International that since the incident, in accordance with the company's policy of continuous improvement, Tosco Keymax has implemented additional inspection regimes and provided information and further training to ship's staff relevant to issues arising from the grounding.
ATSB assessment of action
The ATSB remains concerned that there is no proper guidance provided to the master or crew with regard to how fatigue levels should be managed and when someone should make the fact known that they might not be fit to undertake a navigational watch.
