The Department of Transport has issued a new Marine Notice updating safety guidance for liquefied petroleum gas (LPG) systems on vessels.
Marine Notice No. 14 of 2026 replaces the previous 2017 guidance and applies to merchant ships, fishing vessels, pleasure craft and other marine users.
The update follows recommendations from the Marine Casualty Investigation Board and reflects current international standards for LPG installations.
The Department said LPG remains a “cost effective and versatile fuel” but urged operators to consider alternatives such as electricity or gas oil where possible.
It warned that incorrect handling of LPG systems can lead to fire, explosion, burns and asphyxiation. Past incidents have resulted in “loss of life and material damage”.
The notice outlines updated requirements for installation, ventilation, storage and system testing. It recommends compliance with ISO 10239:2025 standards and stresses the need for expert installation and regular inspections.
Monthly checks of LPG systems, alarms and ventilation are advised, alongside annual servicing by a registered gas installer.
The guidance also highlights the importance of gas detection systems, noting they are required where LPG appliances are installed below deck.
Operators are reminded that LPG is heavier than air and can accumulate in low areas, creating explosive conditions if ignited.
The Department emphasised that proper ventilation and adherence to safety procedures are critical to reducing risk on board vessels.
