Offshore Supply Vessel HARMONIE P Detained at Onne

The offshore supply vessel HARMONIE P has been detained following a Port State Control inspection at the Nigerian port of Onne, conducted on 03 Nov 2026 under the Abuja MOU regime. Inspectors recorded nine deficiencies during the examination of the vessel, though none were classified as detainable deficiencies under the applicable criteria. Despite this classification, port authorities proceeded to detain the ship, a decision that will require rectification of the identified issues before the vessel is cleared to resume operations. HARMONIE P, which sails under the flag of Saint Vincent and the Grenadines, carries IMO number 9331309. The vessel has a gross tonnage of 2,321 and a deadweight of 3,205 tonnes, placing it among smaller offshore support craft typically used to service oil and gas installations along the West African coast. The Abuja MOU, which oversees port state control in the West and Central African region, regularly conducts such inspections to verify compliance with international safety, pollution prevention, and crew welfare standards. Further details regarding the specific deficiencies identified aboard HARMONIE P, and the timeline for the vessel's release, have not been disclosed.
