Houston-based pipeline operator Enterprise Products Partners and British liquefied gas shipping company Navigator Holdings exported the first cargo of ethylene from their new terminal at Morgan’s Point on the Houston ship channel. A Liberian tanker named Navigator Europa left Jan. 2 with a 25-million-pound shipment of ethylene for the Marubeni Corp. in Japan. Enterprise and Navigator entered into a 50-50 joint venture to build storage terminals and docks for ethylene at Enterprise’s export terminal in Morgan’s Point. The export terminal is connected by pipeline to Enterprise’s complex in Mont Belvieu.
