Oil/Chemical Tanker Gulf Petroleum 4 Detained in Constanta

The oil/chemical tanker GULF PETROLEUM 4 (IMO 9439345) was detained following a Port State Control inspection in Constanta on 11 Sep 2026, conducted under the Black Sea MOU. Inspectors recorded a total of 18 deficiencies aboard the vessel, though none of the findings were individually classified as detainable. The vessel, flagged in the Marshall Islands, has a gross tonnage of 8,539 and a deadweight of 13,006. It is managed under the ISM Code by Silver Star Ship Management FZE. Despite the absence of individually detainable deficiencies, the cumulative number and nature of the findings led Port State Control authorities to detain the ship pending corrective action. Port State Control regimes such as the Black Sea MOU conduct inspections to verify that foreign-flagged vessels calling at member ports comply with international safety, pollution prevention and labour conventions. Detentions are issued when a ship is deemed unfit to proceed to sea without posing a risk to the vessel, crew or the environment. No further details regarding the specific deficiencies identified or the expected duration of the detention have been released. The vessel is expected to remain in port until the issues are rectified and a follow-up inspection confirms compliance, allowing it to resume operations.
