A Thorco Projects-managed ship has been banned from Australia for failing three port state inspections this year.

The action against the 17,000-dwt Thorco Luna (built 2014) was taken by the Australian Maritime Safety Authority (AMSA) after the vessel "consistently" failed to meet international standards.

The chartered-in cargo vessel was released from its latest detention at Port Kembla on Friday. It was underway off Sydney on Monday.
