Chemical Tanker NEREIDA Detained at Port of Aden

The chemical tanker NEREIDA (IMO 9163269), flagged in Mozambique, was detained following a Port State Control inspection carried out at Aden on 08 Sep 2026 under the Indian MOU regime. Inspectors recorded a total of 15 deficiencies during the examination, one of which was assessed as detainable, resulting in the vessel being held at port. The inspection was conducted as part of routine Port State Control oversight under the Indian Ocean Memorandum of Understanding, which monitors compliance of foreign-flagged vessels calling at member ports with international safety, pollution prevention and crew welfare conventions. The specific nature of the deficiencies identified aboard NEREIDA has not been detailed beyond the overall count and detention status. The vessel's ISM Company is listed as ONTARIO MARITIME SERVICES SA, which bears responsibility for ensuring the ship's compliance with the International Safety Management Code. Detention will remain in effect until the identified detainable deficiency is rectified and the vessel is re-inspected and cleared to the satisfaction of Port State Control authorities at Aden. Detentions under MOU frameworks such as the Indian Ocean MOU are typically made public to promote transparency in shipping safety standards and to alert other port authorities and charterers to vessels requiring closer scrutiny on subsequent calls.
