Washburn & Doughty Associates, USA, delivered the 'Loretta B Moran' to Moran Towing of Lake Charles on February 9.
The 30-metre,4,920kW Z-Drive tug is the sister to the 'Catherine C Moran', which was delivered on November 10, 2009.
Both tugs will provide tug services for Sempra LNG's new Cameron LNG terminal, located near Hackberry, Louisiana.
