Driving Factors for use of LNG
Lower cost compared to ultra low sulpher marine diesel
ECA (Emission Control Area) requirements:
Maximum level of sulphur in fuel, all ships: 10,000 ppm by 1st July 2010 1,000 ppm by 1st January 2015
Nitrogen emission for newbuilds: 80% reduction in NOx emission
from 2016 on.

USCG Current Approach
Coast Guard analysis has been on a Case-By-Case Basis
● Concepts have used IMO Interim Guidelines as a baseline standard
● Additional requirements tailored to each specific review
● Design Basis – framework of standards and requirements
Equivalent level of safety to Title 46 CFR
Bridging Gaps Design

CFR cites Policy (Until regs are developed)
CG-ENG 01-12 (Ship – published 4/19/2012) CG-OES XX-12 (Ops & Trng – Under development)
CG-ENG 01-12 Policy Letter Establishes design criteria for natural gas fuel systems that provides an
equivalent level of safety compared to traditionally fueled vessels designed to US regulations
Outlined to align section by section with IMO Res. MSC.285(86) Provides direction to specific US standards (e.g. ASME B31.3, ASME
BPV Code, ANSI, NFPA, etc.) Provides direction to specific US regulations (e.g. 46 CFR Part 56,
154) Establishes requirements beyond those required by IMO in several
areas (e.g. gas detection, testing of gas tanks and gas piping) Rulemaking underway to establish regs based on current policy
CG-OES Policy Letter Interim guidelines for fuel transfer operations and training for
personnel working on vessels that use natural gas as fuel Specifies acceptable fuel sources Aligns with existing regs concerning fuel transfer procedures (33 CFR
Part 154, 155, and 156) Aligns with existing regs concerning LNG waterfront facilities (33
CFR Part 127) Aligns with IMO Res. MSC Circ.285(86) & Swedish Marine Forum Requires Operations, Maintenance, Training, and Emergency Manuals Outlines requirements for personnel training & PIC quals Policy is going through internal clearance Concepts to be part of Rulemaking effort
