ASNE So. New England Section Hears Gen'l Dynamics Paper On LNG Spheres

The quarterly meeting of the American Society of Naval Engineers, Southern New England Section, was held recently in New London, Conn. Capt. Don Kern, USN (ret.), chairman of the Section, presided over the meeting.

The large-scale ocean transportation of liquefied natural gas (LNG) to meet energy needs has presented a major challenge of the decade for ship designers and builders. One of the schemes be ing implemented employs 120-foot aluminum spheres for LNG containment. Fritz G. Tovar, general manager of the General Dynamics Quonset Point facility, talked about the manufacture of these spheres at the General Dynamics South Carolina facility. He also showed a film of the facility and the 936-foot LNG General Dynamics ships, several of which have been delivered. His talk covered the manufacture and instal- belation of the 800-ton spheres from aluminum plate baking, forming, edge milling, welding, testing, and insulating to final i n s t a l l a t i o n. Each sphere contains 50 miles of aluminum welding. General Dynamics has invested $100 million in the South Carolina facility to produce one sphere every two and one-half weeks.

Mr. Tovar concluded his presentation with a talk and slide show on the $110-million General Dynamics Quonset Point facility for the manufacture of submarine hulls using s o p h i s t i c a t ed equipment.

Mr. Tovar worked as a design engineer in West Germany before becoming manager of the Davie Shipyard in Quebec, Canada. He joined General Dynamics as manager of the South Carolina facility, and for the past two years has been general manager of the General Dynamics Quonset Point facility.
