Oil Tanker Atlantic Onyx Detained in Sydney

The oil tanker ATLANTIC ONYX was detained following a port state control inspection conducted on 14 Sep 2026 at the port of Sydney, NSW, under the Indian Ocean MoU regime. Inspectors recorded a total of four deficiencies during the inspection, one of which was assessed as detainable, prompting authorities to hold the vessel in port until the issue is rectified. The IMO number of the ship is 1078274, and it sails under the flag of Liberia. The vessel is managed under the ISM Code by Eastern Pacific Shipping P/L, which bears responsibility for ensuring the ship's compliance with international safety and operational standards. Port state control detentions are issued when deficiencies are judged serious enough to pose a risk to the safety of the ship, its crew, or the marine environment, and the vessel must address the detainable deficiency and undergo a follow-up inspection before being permitted to depart. No further details on the nature of the detainable deficiency have been disclosed. Port state control regimes such as the Indian Ocean MoU coordinate inspections among member states to enforce compliance with international maritime conventions, and detention records are typically published to promote transparency and support efforts to eliminate substandard shipping.
