Vietnamese Gas Carrier Thang Long Gas Detained in Imabari

The gas carrier THANG LONG GAS (IMO 9343704) was detained on 02 Nov 2026 following a Port State Control inspection at the Japanese port of Imabari, conducted under the Tokyo MOU regime. Inspectors recorded a total of eight deficiencies aboard the vessel, two of which were assessed as detainable, prompting authorities to hold the ship in port pending rectification. The vessel, flagged in Vietnam, has a gross tonnage of 3,434 and a deadweight of 4,002 tonnes. THANG LONG GAS is managed under the ISM Code by INTERNATIONAL GAS PRODUCTS SHIPPING JSC, also known as GAS SHIPPING JSC. The company will be required to address the identified deficiencies before the vessel is cleared to resume operations. Port State Control inspections under the Tokyo MOU framework are designed to verify compliance with international safety, pollution prevention and crew welfare standards among vessels calling at ports across the Asia-Pacific region. Detentions are imposed when deficiencies are judged serious enough to pose a risk to the safety of the ship, its crew, or the marine environment, and typically remain in effect until the flag state or classification society confirms that corrective action has been completed.
