En route to her sea trials, the LNG Aquarius "squeezes" through the Fore River Drawbridge. Three of her five sisterships currently under construction at the Quincy shipyard are shown in the background.

The LNG Aquarius Is The First

Of Twelve LNG Tankers

Being Built By General Dynamics by the shipyard's 1,200-ton-capacity Goliath crane, the largest in the Western Hemis- phere.

The highly sophisticated LNG Aquarius will carry a crew of 30, will have a top speed in excess of 20 knots, and can load and dis- charge its cargo in 12 hours.

Quincy has the capacity to build four of the LNG tankers yearly.

The largest liquefied natural gas (LNG) tanker ever built in the U.S. was named on

May 27, during ceremonies at General Dy- namics Quincy shipyard in Massachusetts.

Mrs. David S. Lewis, wife of the chairman and chief executive officer of General Dy- namics, officially named the supertanker LNG

Aquarius, before a crowd of several thousand invited guests and shipyard workers and their families gathered at the yard.

The 936-foot-long, 95,000-ton vessel is the

Five of the 12 ships will be used to trans- port LNG from Algeria to the U.S. East and

Gulf Coast ports, while the other seven will carry gas from Indonesia to Japan.

All the ships will operate under American registry and will be manned by American crews.

The LNG Aquarius has been delivered and will enter initial service on the Indonesia to

Japan route later this year under long-term charter to a subsidiary of Burmah Oil Com- pany.

The naming ceremony culminated more than three years of construction effort on the LNG Aquarius, one of the most techno- logically advanced merchant ships ever built.

The tanker will carry 125,000 cubic meters of liquefied natural gas on each trip, enough gas to serve an American city of 500,000 for a month. The gas will be carried in five 120-foot-diameter spherical aluminum cargo tanks at a temperature of minus 265 degrees

Fahrenheit. The 2-inch-thick walls of the tanks are covered with 9 inches of polyure- thane insulation to help maintain the very low temperature and prevent boil-off of the gas. The liquefaction process reduces the vol- ume of the gas some 600 times.

The 850-ton spherical tanks are produced at General Dynamics Charleston, S.C., fabri- cation facility and transported to Quincy by barge, where they are installed in the tankers
