Tanzanian-Flagged Tanker Bonanza Detained in Ensenada

The oil/chemical tanker BONANZA (IMO 8821747), flagged in Tanzania, was detained on 05 Nov 2026 following a Port State Control inspection under the Tokyo MoU at the port of Ensenada. Inspectors recorded three deficiencies during the examination, two of which were classified as detainable, prompting authorities to hold the vessel pending corrective action. Specific details of the deficiencies were not disclosed in the inspection report. The BONANZA has a gross tonnage of 4,609 and a deadweight of 7,035 tonnes. The vessel is managed under the International Safety Management Code by Constructora, Arrendadora y Equipo Cimar SA de CV, which is responsible for addressing the identified deficiencies before the ship can be cleared to resume operations. Port State Control inspections under regional memoranda of understanding such as Tokyo MoU are conducted to verify that foreign-flagged vessels comply with international safety, pollution prevention, and crew welfare standards. Detention remains in effect until the flag administration or classification society confirms that the deficiencies have been rectified and the vessel is fit to sail.
