Huntington Ingalls Industries will study redeveloping its Avondale, La., shipyard in conjunction with Kinder Morgan Energy Partners.
The two companies say they could form a joint venture to redevelop the shipyard near New Orleans.
Houston-based Kinder Morgan is the nation's largest pipeline company, transporting petroleum products, natural gas and carbon dioxide. It also runs petroleum terminals and stores natural gas.
Northrop Grumman announced in 2010 that it would close Avondale, shifting operations to its Pascagoula, Miss., shipyard. It later spun off those and other shipyard operations as Huntington Ingalls, based in Newport News, Va.
Huntington Ingalls has been trying to transfer Avondale to someone who would redevelop it, but has found no takers. Most of the remaining 740 employees would be laid off this summer without a new user.
