The Italian Coast Guard (Guardia Costiera) recently reported the detention of a small container ship due to uncertainty over its emissions compliance. This year, the Mediterranean became an Emission Control Area (ECA), and Italian authorities have detained 10 vessels so far for failing to meet international regulations.

On August 21, 2025, the Hansa Hornenburg (23,644 dwt) arrived in Genoa from Vado Ligure, Italy. The ship is Liberia-flagged, managed by Germany’s Leonhardt & Blumberg, built in China in 2007, and has a capacity of 1,732 TEU.

Italian authorities inspected the vessel and found that, although it held valid certificates, they could not confirm full compliance with nitrogen oxide (NOx) regulations. Components of the ship’s generators lacked compliance markings, leaving uncertainty regarding adherence to NOx technical standards.

The Guardia Costiera conducted thorough inspections from the bridge to the engine room and crew areas, including safety drills. Due to the inability to ensure compliance, the vessel was detained. Previous inspections in the U.S. and Peru had reported no issues.

Since May 1, 2025, the Mediterranean is officially an IMO Sulfur Emission Control Area (ECA). The International Maritime Organization emphasizes that vessels operating in new ECAs are subject to strict mandatory measures to prevent, reduce, and control air pollution.

AIS data shows that as of August 29, the Hansa Hornenburg remains in Genoa. Italian authorities stated that, under supervision of the flag state government and classification society, the ship will remain detained until deficiencies are corrected and will require follow-up inspections by port state control.
