DNV Issues Guidance on Ship Emergency Escape Trunks for SOLAS Compliance

DNV has issued guidance regarding the arrangement of emergency escape trunks from machinery spaces on ships, as some vessels have been detained during Port State Control inspections due to non-compliance with SOLAS regulations. The protected emergency escape trunk on many ships does not extend all the way down to the lowest deck level of the engine room, often requiring an inclined ladder for access. PSC authorities are focusing on vessels built after February 1, 2016, to ensure compliance with IACS UI SC 276/277, and are scrutinizing escape trunk arrangements that do not reach the lowest deck level.

Some PSC inspectors are requesting crew members to conduct evacuation drills to demonstrate their ability to evacuate an injured person from the lowest deck, up the ladder, and into the protected trunk. Failure to meet the satisfaction of the PSC officer during these drills could lead to detention. For vessels with escape trunks that do not extend to the lowest deck level, a technical justification may be required by flag and/or port state control. The IMO Sub-Committee on Ship Design and Construction has agreed to further consider this matter in upcoming meetings.

DNV recommends updating the Safety Management System to include procedures for rescue drills and conducting regular drills to familiarize the crew with emergency escape arrangements. For ships with escape trunks not extending to the lowest deck level, a technical justification should be developed and accepted by the flag administration, kept on board the vessel, and made available for inspection by PSC or other parties as needed. DNV offers assistance in this process to ensure compliance with regulations and smooth inspections.
