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”

– 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

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

Study Overview

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
