The Project:

Foss Maritime has been deeply involved in the design and construction of the first U.S. flagged liquefied natural gas (LNG) bunker barge, the Clean Jacksonville. Foss provided project management and bunkering operations, as well as subject matter expertise and formed an LNG operations team who will operate the barge in support of Tote Maritime Puerto Rico’s, LNG-Powered, Marlin Class Vessels.

Services Provided:

  • Naval Architecture
  • Marine Engineering
  • Project Management


  • The Clean Jacksonville has a towing speed of up to 8 knots and a storage capacity of 2,200 m3, with atmospheric membrane tanks that conform to the hull shape to maximize use of space.
  • The barge uses the latest leak detection technology and emergency shutdown systems to meet strict regulatory requirements.
  • LNG vessels have made more than 105,000 LNG carrier voyages without major accidents or safety problems, either in port or at sea.
  • Foss worked with the U.S. Coast Guard to develop a recruitment process to define areas of expertise required for crew positions.
