51 Fall 2015 Proceedings but many regulations may not be practical or applicable to barges' specifc needs. To address this void, Coast Guard personnel consulted with the Chemical Transportation Advisory Committee 8 and members of the public to obtain recommended design stan- dards for barges carrying LNG in bulk, and Coast Guard personnel are preparing a policy letter to guide submitters in LNG barge design. In the meantime, submitters may still provide proposals to the Marine Safety Center, under the existing rules, and request a design basis to clarify detailed design issues or alternative arrangements. The next generation of LNG barges is coming. The Coast Guard, through industry partnerships, is proactively devel- oping guidelines to ensure safe development for this fuel option. The transition to liquefed natural gas fuel will pose new risks for the maritime community, but it is also a prom- ising new option for our environment and economy. Since the move toward its wide adoption calls for a responsible approach, the goal should be proftable, productive, and innovative use that focuses on safety, responsibility, and protection.
