Feature 5 | AMERICAS Cleaning up in Jacksonville
A shipyard in Texas has completed a groundbreaking project in support of the US uptake of LNG as marine fuel. David Tinsley reports
Clean Jacksonville has been hailed as the US’ first non-self-propelled barge to embody a GTT membrane system

Membrane tank Following construction at Conrad Industries’ Conrad Orange Shipyard in Orange, Texas, Clean Jacksonville was transferred to Port Fourchon, Louisiana for gas trials at Harvey Gulf International Marine’s LNG bunkering facility, prior to taking up station in northeast Florida. Designed and engineered by the
Rhode Island-based Bristol Harbor Group (BHGI), the barge is installed with a single membrane tank of the Mark III Flex type developed by LNG containment technology specialist Gaz Transport & Technigaz (GTT) which is headquartered in France. BHGI cooperated with all parties involved to obtain ABS and US Coast
Bunker mast Clean Jacksonville signifies further technological milestones for North America as the first non-self-propelled barge to embody a GTT membrane system and the first ever project to feature the French company’s innovative REACH4 LNG bunker mast. Denoting ‘Refuelling Equipment Arm,
CH4 Methane’, the REACH4 bunker mast applies methods for conventional fuelling adapted to LNG-specific constraints, and is well suited for bunkering most ships, whatever their bunker station arrangement. The mast is fitted with breakaway couplings for safe and reliable emergency disconnections. The barge features a vapour return
capability from the recipient vessel, and is equipped with an LNG re-cooling unit, designed to optimise the use of any excess boil-off generated in the tank. GTT support also extended to relevant fields of training for the barge crew, commissioning and gas trials. The North American subsidiary of
the French company signed a technical assistance and licence agreement with Conrad Shipyard in January 2015, spanning the design and construction of LNG barges and the bunker tanks of LNG-fuelled vessels using GTT membrane designs. SBI
