Safety Alerts and Bulletins Specific to Liquefied Gas as Fuel
Mr. Scott Mercurio
USCG Marine Safety Alert 05-20 Subject: Electrical Issues Spark Major Concern – Addressing Hazardous Area Electrical Installations Knowledge Gaps.
Narrative: The purpose of this Safety Alert is to emphasize the importance of properly installed and maintained listed or certified safe electrical equipment in hazardous areas in order to reduce the risk of fire or explosion onboard vessels. The Coast Guard has seen a number of instances where there was a lack of knowledge in the marine industry as it relates to the installation, training, maintenance and inspection of these certified systems.
Society for Gas Marine Fuel (SGMF) Formal Safety Notice (FSN) No: FSN 19-01 Subject: Prevention of LNG leakages from dry-disconnect/connect couplings.
Narrative: Differential movement between supply and receiving bunkering equipment is causing leakages at the dry-disconnect/connect coupling sealing face/surface. It is not clear that and design loads are being exceeded shills this movement is occurring, however it is causing the coupling to leak.
* SGMF SGMF is recognized as the leading experts in the use and adoption of low flashpoint fuels for shipping and the ensuing supply infrastructure. This is where knowledge and best practice are gathered from the wide experience of our members which encompasses all the value chain for the fuel including producers, suppliers, owners, operators, port authorities and classification societies and equipment manufacturers, making SGMF the largest and best represented organization of its kind.
