Eastern Shipbuilding’s Vision for U.S. Inland Waterways friendly, highly maneuverable Inland Towboat design.
Eastern has worked with Gilbert Associates, Inc. develop- ing its new fresh hybrid THUNDERBOLT diesel electric design. The THUNDERBOLT has been designed using
ABS Class Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways-2014. It is also designed to the Proposed U.S. Coast Guard 46CFR (Sub-Chapter M) Towing Vessel Rules and IEEE 45 2002
Standards. In a nutshell, the THUNDERBOLT is a 120’

Harvey Energy: Historic First for U.S. LNG Power
The ? rst ABS Classi? cation Certi? cate and the ? rst
USCG Certi? cate of Inspection for a vessel powered by
LNG have been issued to Harvey Gulf Marine’s Harvey
Energy. The M/V Harvey Energy is the ? rst LNG powered vessel in service in North America. Earlier, Harvey Gulf celebrated the ? rst truck to vessel transfer of LNG, the ? rst vessel to bunker LNG and was the ? rst U.S. Flagged LNG powered vessel to enter into port while being powered by
LNG. The vessel will be based out of Port Fourchon, LA and will immediately begin its long term charter role.
