H—4 Distrigas LNG Barge Operating Experience
The barge Massachusetts is a double-hulled, ocean-going LNG carrier. It is classed by the American Bureau of Shipping as an A1 ✠ Pressure Tank Barge* suitable for carrying LNG, LPG, and ethylene. It is of notched-stern design, and is normally propelled in integrated mode by tug as in Fig. 1 ; in heavy seas it is towed on a hawser. Its four aluminum cylindrical cargo tanks have a total nominal capacity of 30,800 bbl and a net delivery capacity of approximately 27,000 bbl. Since its commissioning in October 1973, it has been the only U. S. flag LNG carrier.
