5 LNG Safety: Lessons Learned? Truck to ship bunkering of Norwegian Ferry Bergensfjord May kg of LNG leaked from hose connection Hose disconnect due to ship stabilizing system not engaged No injuries, no damage- but dangerous situation created Additional safety procedures imposed by regulators Extension of safety zone No passenger / car loading during bunkering Extra personnel from supplier on dock Copyright 2016 United States Maritime Resource Center, Inc.

7 US LNG Fuel Vessel Design Guidance 1. IMO MSC 285 (86) INTERIM GUIDELINES ON SAFETY FOR NATURAL GAS-FUELLED ENGINE INSTALLATIONS IN SHIPS Bridging document until IGF Code enters into force Jan 2017 Provides design criteria for building LNG fueled ships Considered base line standard by USCG for evaluation and equivalency determination 2. USCG Policy Letter EQUIVALENCY DETERMINATION Establishes design criteria for Equivalent Level of Safety Modifies certain provisions of IMO 285 (86) above Not a regulation, has no legal force, not mandatory LNG fueled vessels meeting the design criteria may be approved by USCG Copyright United States Maritime Resource Center, Inc.

9 Fuels Addressed by the IGF Code Low-flashpoint fuel - gaseous or liquid fuel having a flashpoint lower than 60 C or 140 F For now, the IGF code will address natural gas as fuel Regulations for other fuels will be developed when and as needed Other Low Flashpoint Fuels: Propane Butane Ethanol Methanol Hydrogen Dimethyl-ether (DME) This course is focused on natural gas fueled vessels Copyright 2016 United States Maritime Resource Center, Inc.
