Between April 1, 2025, and June 30, 2025, port state control (PSC) regimes under the Paris MoU, Tokyo MoU, and the US Coast Guard (USCG) detained a total of 492 vessels. Of these, only 25 vessels were ABS-classed ships, representing just 5.08% of total detentions highlighting ABS’s strong performance in compliance and operational safety.
Key Detention Categories for ABS Vessels
During the inspections, the top deficiencies leading to detentions of ABS-classed vessels included:
-
Safety Management (ISM) compliance
-
Fixed fire extinguishing installations
-
Emergency fire pump and piping issues
-
Lifeboat readiness and launching arrangements
-
Oil filtering equipment
-
Sewage treatment plant functionality
-
Seafarers’ employment agreements (SEA) compliance
-
Scuppers, inlets, and discharges
-
SART/AIS-SART equipment performance
-
Ventilation systems
-
Navigation lights, shapes, and sound signals
-
Automatic Identification System (AIS)
-
Bridge operation procedures
-
Ship and equipment maintenance
These deficiencies indicate that while ABS vessels had a lower detention rate overall, fire safety, lifesaving equipment readiness, and environmental compliance remain focus areas for improvement.
Top Countries for PSC Interventions on ABS Vessels
For Q2 2025, the countries with the highest number of PSC interventions involving ABS-classed ships under the Paris MoU, Tokyo MoU, and USCG inspections were recorded. These intervention hotspots help ABS and ship operators target compliance efforts more effectively, ensuring higher safety standards and reduced operational risks in future inspections.
The Q2 2025 results reaffirm ABS’s position as a leader in maritime safety compliance, with one of the lowest detention rates among major classification societies. However, the recurring categories of deficiencies point to specific areas particularly fire safety systems, lifesaving equipment, and environmental controls that require continuous monitoring and preventive maintenance.
Strengthening these aspects will help ensure that ABS vessels maintain their strong compliance record in upcoming inspection cycles.
