IACS Releases Findings from Emergency Power Supply Inspection Campaign on Ships
The International Association of Classification Societies (IACS) has published the results of its Concentrated Inspection Campaign on Emergency Power Supply Tests conducted on ships throughout 2025. This campaign was initiated in response to concerns from the Tokyo MoU regarding the reliability of 'simulated blackout' tests in demonstrating compliance with the Safety of Life at Sea (SOLAS) requirements. Over the course of the year, inspections were carried out on 36,723 ships, revealing deficiencies in 853 cases, which is about 2.32% of the total. The campaign identified several critical equipment failure points, including issues with quick-closing valves, control units, and emergency diesel generator starting arrangements. Additionally, non-equipment deficiencies such as inadequate blackout test procedures in Safety Management Systems were noted. The findings highlight the need for improved maintenance, installation quality, and crew training to ensure compliance with SOLAS standards.
