(www.MaritimeCyprus.com) The 2025 reporting period was affected by the ongoing armed conflict between the Russian Federation and Ukraine, which continued to pose serious risks to the safety and security of crews and vessels operating in the region and not boding well with the BS MoU’s objectives in promoting maritime safety and security, and environmental protection. Throughout 2025, a total of 5,117 inspections was conducted on 3,231 individual ships in the Black Sea Region, covering ships registered under 74 Flag Administrations. This figure represents an 11.6% increase compared to the 4,587 inspections conducted in 2024. While this increase reflects a positive recovery in inspection activity, the total number of inspections remains approximately 3% below the ten-year average of 5,274 inspections under the New Inspection Regime, which has been in force since 1 January 2016. A notable development in 2025 was the significant rise in the average detention percentage, which rose to 6.78%. This represents the highest level recorded since 2007 and the third highest since the establishment of the Black Sea MoU, with only 2007 (8.16%) and 2004 (6.95%) having higher rates. The upward trend in detentions has been consistent since the post-Covid-19 Pandemic period, with rates rising from 3.17% in 2021 to 3.50% in 2022, 3.93% in 2023, 4.69% in 2024, and 6.78% in 2025. This pattern underscores the critical role of effective port State control in addressing substandard shipping and safeguarding maritime safety and the marine environment. Due to the ongoing war, exact data on the number of individual ships operating in the region was unavailable. As a result, data for the broader region was not accessible. Therefore, for the purposes of this analysis, it has been assumed that throughout the year, vessels calling at Ukrainian ports also visited at least one port in other Member States. Based on this assumption, the regional inspection rate for 2025 (calculated as individual ships
