Panama-Flagged Tug JIANG JUN Detained in Shanghai

The tug JIANG JUN (IMO 9483645), flagged in Panama, was detained in Shanghai on 12 Nov 2026 following a Port State Control inspection conducted under the Tokyo MOU framework. Inspectors identified five deficiencies during the examination, three of which were classified as detainable, prompting authorities to hold the vessel in port until the issues are resolved. The specific nature of the deficiencies has not been disclosed in the inspection report. The JIANG JUN is a small tug with a gross tonnage of 495 and a deadweight of 327 tonnes. Vessels of this type are typically used for towage, harbor assistance and offshore support operations. Port State Control detentions under the Tokyo MOU are issued when inspectors determine that deficiencies pose a risk to the safety of the ship, its crew, or the environment, or when the vessel fails to meet the requirements of relevant international maritime conventions. The vessel will remain detained in Shanghai until the identified deficiencies are rectified and verified by port authorities, after which it may be cleared to resume operations.
