Offshore Supply Vessel Dreadnought Detained in Rizhao Over Deficiencies

The offshore supply vessel DREADNOUGHT (IMO 9155664) was detained by port state control authorities in Rizhao following an inspection conducted on 23 Sep 2026. The inspection, carried out under the Tokyo MOU regime, identified 14 total deficiencies, of which 5 were classified as detainable, resulting in the vessel being held in port pending rectification. The Mongolia-flagged vessel has a gross tonnage of 1,974 and is managed under the ISM Code by Y& Y Maritime Management & Consultancy Sdn Bhd. Details of the specific deficiencies identified during the inspection have not been disclosed in the detention report. Port state control inspections under the Tokyo MOU are conducted to verify that foreign vessels calling at member ports comply with international safety, security and environmental standards, including those set out under SOLAS, MARPOL and the ISM Code. Detentions are issued when deficiencies are deemed serious enough to pose a risk to the ship, crew or the environment, requiring the vessel to remain in port until the issues are addressed and verified by inspectors. The DREADNOUGHT will remain detained in Rizhao until the identified deficiencies are corrected and the vessel is cleared for departure by port state control authorities.
