1. United States Coast Guard Marine Safety, Security, and Stewardship Applying Industry Standards to LNG Marine Fuel Systems Applying Industry Standards to LNG Marine Fuel Systems ASTM Workshop Washington, DC – May 7, 2014 Timothy E. Meyers, PE Office of Design & Engineering Standards U.S. Coast Guard Headquarters

2. United States Coast Guard Marine Safety, Security, and Stewardship Outline Background on issue – Why LNG as a Marine Fuel? Current regulatory landscape Review process for gas-fueled vessel design Development of related industry standards Incorporation of standards into policy Opportunities / need for additional industry standards 2

3. United States Coast Guard Marine Safety, Security, and Stewardship Why LNG as Fuel? 3

4. United States Coast Guard Marine Safety, Security, and Stewardship Driving Factors for Use of LNG  Emission Control Area (ECA) requirements: Maximum level of sulphur in fuel, all ships: o 10,000 ppm by 1st July 2010 o 1,000 ppm by 1st January 2015 Nitrogen emission for new buildings: o 80% reduction in NOx emission from 2016 on.  Lower cost compared to marine diesel 4 North American ECA

5. United States Coast Guard Marine Safety, Security, and Stewardship 5 Recent Interest in the U.S. TOTE LNG-Fueled Containership Harvey Gulf LNG-Fueled OSV TOTE RO/RO Containership LNG Retrofit

6. United States Coast Guard Marine Safety, Security, and Stewardship 6 How to Proceed Without Requirements for Gas Fueled Vessel Design?  Federal Regulations do not address natural gas as fuel  Need to establish equivalency to Title 46 CFR  Vessel-specific concept review  Design Basis – framework of standards and requirements Equivalent level of safety to Federal Regulations (Title 46 CFR) CFR

7. United States Coast Guard Marine Safety, Security, and Stewardship USCG Involvement in Standards Development 7

8. United States Coast Guard Marine Safety, Security, and Stewardship 8 Related Industry Standards Class Society Rules & Guides Interim Guidelines on Safety for Natural Gas-Fuelled Engine Installations in Ships

9. United States Coast Guard Marine Safety, Security, and Stewardship IMO - Code for Gas Fueled Ships 9  “Interim Guidelines for Gas-Fueled Ships” IMO Resolution MSC.285(86) o Adopted 1 June 2009  International Code of Safety for Ships Using Gases or Other Low- Flashpoint Fuels (  International Code of Safety for Ships Using Gases or Other Low- Flashpoint Fuels (IGF Code) o Draft completion expected Sep 2014 o Earliest “in force” date: 2017

10. United States Coast Guard Marine Safety, Security, and Stewardship 10 ISO - LNG Fuel Bunkering Guidelines ISO/TC67 Working Group 10 “Guidelines for Systems and Installations for Supply of LNG as Fuel to Ships” o started work in 2011 o draft completed: Jan 2014 o once adopted, will be published as a Technical Specification

11. United States Coast Guard Marine Safety, Security, and Stewardship 11 NFPA 52 - Vehicular Gaseous Fuel Systems Code  revision cycle for 2016 edition o working with NFPA to evaluate outdated chapter on “Marine Vessels & Pleasure Craft” o possible alternative standard for smaller vessels in domestic service

12. United States Coast Guard Marine Safety, Security, and Stewardship 12 Incorporation of Standards in Policy USCG Policy Letter 01-12  provides streamlined review process  “equivalent level of safety” to 46 CFR  baseline: IMO Interim Guidelines  add’l requirements & modifications  designs outside policy can still apply for “concept Review”

13. United States Coast Guard Marine Safety, Security, and Stewardship 13 Other Standard Referenced  Fuel System Piping o ASME B31.3 – Process Piping Tanks o ASME Boiler & Pressure Vessel Code, Section VIII Div 1 and 2  Fire Protection Installed firefighting systems o IMO MSC.1/Circ.1315  Hazardous Locations Classification of hazardous areas & electrical equipment o NEC (NFPA 70) Articles 500 - 505 o IEC 60092-502 & 60079 Series o UL, FM, ISA, & CSA standards  Gas Detection System certification o IEC 60079 & 60092 Series

14. United States Coast Guard Marine Safety, Security, and Stewardship 14 Need to Address Fueling Infrastructure

15. United States Coast Guard Marine Safety, Security, and Stewardship 15 Other Policy Under Development Draft CG-OES Policy Letter 01-14  LNG Fuel Transfer Operations & Personnel Training Draft CG-OES Policy Letter 02-14  Waterfront Facilities & Vessels Transferring LNG as Fuel

16. United States Coast Guard Marine Safety, Security, and Stewardship 16 Opportunities for Additional Standards  Bunkering hose  Bunkering “dry disconnect” fittings  Dry break-away coupling/self-sealing quick release  ESD system
