Oil Tanker MARVEN Detained in Kocaeli After PSC Inspection

The oil tanker MARVEN (IMO 9305556) was detained at the Turkish port of Kocaeli following a Port State Control inspection conducted under the Mediterranean MoU on 14 Jan 2026. Inspectors recorded 15 deficiencies in total, four of which were classified as detainable, prompting authorities to hold the vessel in port. The MARVEN is a Palau-flagged oil tanker with a gross tonnage of 65,293. The vessel is managed under the International Safety Management Code by PENG HU WAN SHIPMANAGEMENT CO. LTD., which bears responsibility for addressing the identified deficiencies before the ship can resume operations. Detentions under the Mediterranean MoU framework are issued when inspectors determine that conditions on board pose a risk to safety, the environment, or compliance with international maritime regulations. The vessel will remain detained in Kocaeli until the outstanding deficiencies are rectified and verified by Port State Control authorities, allowing it to be cleared to sail. No further details on the specific nature of the deficiencies or a timeline for release have been disclosed.
