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
North American ECA

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
CFR
 Vessel-specific concept review
 Design Basis – framework of
standards and requirements
Equivalent level of safety to
Federal Regulations (Title 46 CFR)

IMO - Code for Gas Fueled Ships
 “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 LowFlashpoint Fuels (IGF Code)
o
Draft completion expected Sep 2014
o
Earliest “in force” date: 2017

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

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working with NFPA to evaluate outdated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

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”

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

Opportunities for Additional Standards
 Bunkering hose
 Bunkering “dry disconnect”
fittings
 Dry break-away
coupling/self-sealing quick
release
 ESD system
