IMO Regulation – MEPC.1/Circ. 723
� Titled - INFORMATION ON NORTH AMERICAN EMISSION CONTROL AREA (ECA) UNDER MARPOL ANNEX VI
� Amends MARPOL Annex VI to designate the North American Emission Control Area (ECA) for NOx, SOx and particulate matter
� The requirements within the North American ECA for SOx and particulate matter “will be effective on 1 August 2012”
� While in the ECA, the sulphur content of fuel oil used “on board ships shall not exceed 1.00% m/m on and after 1 August 2012, and 0.10% m/m on and after 1 January 2015”

USCG Regulation Development
� Chemical Transportation Advisory Committee (CTAC)
– Working Group for Safety Standards for the Design of Vessels
Carrying Natural Gas or Using Natural Gas as Fuel
– Margaret Kaigh Doyle, Chair
� Task Statement: Identify gaps in current Coast Guard policy and
regulation:
– Design, installation and operation of natural gas fueled systems
for propulsion of commercial vessels
– Design of novel vessels carrying natural gas in bulk
– Fuel Transfer Operation
– Develop acceptable design criteria/ recommendations to help fill
those gaps

� LNG bunker vessels, and
� LNG bunkering facilities
in the development of LNG bunkering projects in North America by describing:
� Regulatory requirements
� Current and planned LNG supply
infrastructure
� State, provincial, port, and local issues
26

LNG Bunkering Risk Drivers
Initiating Events Common Causes
Leaks from LNG
pumps, pipes,
hoses, or tanks
• Corrosion/erosion, fatigue failure, hose failure, & seal failure
• Improper maintenance
• Use of inappropriate hoses (e.g., not LNG rated)
• Vibration
• Improper installation or handling
• Improper bunkering procedures
Inadvertent
disconnection
of hoses
• Improper hose connection or hose failure
• Excessive movement of the loading arm or transfer system
• Inadequate mooring or mooring line failure
• Supply truck drives/rolls or supply vessel drifts/sails away
with hose still connected
• Extreme weather or natural disaster
Overfilling vessel
fuel tanks
• Operator and level controller fail to stop flow when tank is full
External Impact • Cargo or stores dropped on bunkering equipment
• Vessel collides with the receiving or bunkering vessel
• Vehicle collides with bunkering equipment
