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
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
