Coast Guard Office of Design and Engineering Standards (CG-ENG) developed policy letter CG-521 Policy Letter 01-12 "Equivalency Determination - Design Criteria for Natural Gas Fuel Systems". This policy letter establishes design criteria for natural gas fuel systems that provide a level of safety that is at least equivalent to that provided for traditional fuel systems by existing regulations.
Additionally provided below is the International Maritime Organization (IMO) Interim Guidelines on Safety for Natural Gas-Fuelled Engine Installations in Ships.

Coast Guard Office of Hazardous Materials Division (CG-ENG-5) is currently developing policy regarding the design of LNG barges. The starting point for design is regulations in the International Gas Carrier Code (IGC) and Title 46 Code of Federal Regulations (CFR) 154 -Safety Standards for Self Propelled Vessels Carrying Bulk Liquefied Gases.
Point of contact at CG-ENG-5 is Dr. Cynthia Znati, email and contact number is: (202) 372-1412
