Cameroon-Flagged Tanker GRUS I Detained in Chennai

The oil tanker GRUS I (IMO 9224441), flying the flag of Cameroon, has been detained following a Port State Control inspection at Chennai under the Indian Ocean Memorandum of Understanding on Port State Control (Indian MoU). The inspection, carried out on 04 Jul 2026, identified a total of three deficiencies aboard the vessel, one of which was classified as detainable, prompting authorities to hold the ship in port until the issue is resolved. Details of the specific deficiency have not been disclosed in the inspection report. The vessel is managed under the International Safety Management (ISM) Code by SEAPON SHIP MANAGEMENT LLP, which is responsible for addressing the deficiency before the ship can be cleared to resume operations. Port State Control detentions are issued when inspectors determine that a vessel's condition, equipment, or crew certification pose a risk to safety, the environment, or compliance with international maritime regulations. The Indian MoU is one of several regional Port State Control regimes worldwide that coordinate inspections of foreign-flagged vessels calling at member ports to ensure compliance with international conventions. Further updates on the vessel's status are expected once the detainable deficiency has been rectified and verified by port authorities.
