Jones Act liquified ammonia barge launched
US shipbuilder Vigor recently launched Harvest, the first complex liquefied ammonia transport barge built in the United States for Jones Act trade since 1982. The vessel was constructed to support the operations of the Mosaic Company. Harvest will be operated by a subsidiary of Savage Companies as part of an articulated tug and barge (ATB) unit.
Successful completion of the first liquefied gas carrier built in decades hinged on extensive project planning and management between Vigor, multiple contractors, designers and its customer, Savage. Careful integration of various complex systems was required to support Harvest’s state-of-the-art, onboard re-liquefaction plant that keeps cargo cooled to -32° degrees Celcius.
