07-Apr-2015

U.S. Coast Guard CG-OES Policy Letter No. 02-15

Subject:  GUIDANCE RELATED TO VESSELS AND WATERFRONT FACILITIES CONDUCTING LIQUIFIED NATURAL GAS MARINE FUEL TRANSFER (BUNKERING) OPERATIONS.

Content:  This letter provides guidance to owners and operators of vessels and waterfront facilities intending to conduct Liquefied Natural Gas (LNG) fuel transfer operations, and Coast Guard Captains of the Ports (COTPs) who assess fuel transfer operations in accordance with Title 33, Code of Federal Regulations (CFR), Parts 127, 155, and 156, Title 46, CFR, Subchapter D, and the Marine Safety Manual Volume II.  It identifies the minimum safety and security requirements outlined in the federal regulations for LNG fuel transfer operations conducted from vessels and facilities regulated by the Coast Guard, and provides guidance that may be used by COTPs in assessing situations where the regulations are not applicable and/or are not appropriate for a specific operation being considered.  The LNG transfer operations addressed in this letter include bulk liquid transfers conducted from tank vessels (ships and tank barges), waterfront facilities handling LNG in bulk (e.g. storage tanks, mobile tank trucks, and rail cars), and portable tanks containing LNG.  This letter does not address LNG Deepwater Port (DWP) facilities licensed under the DWP Act of 1974, nor does it apply to facilities that handle liquefied hazardous gases other than LNG.  Additionally, this letter does not address design of LNG fuel systems installed on vessels using LNG as fuel or the operations and training requirements for personnel on such vessels; guidance associated with the design of LNG fuel systems and the operations and training on vessels using LNG as fuel is outlined in COMDT (CG-521) Policy Letter 01-12, dated April 19, 2012 and COMDT (CG-OES) Policy Letter 01-15.
