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

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
