NATCHEZ, Miss. — An Ohio company said it’s taking over a south Mississippi plant that makes storage tanks and other large steel products, and it’s adding 75 jobs to the existing workforce.

Enerfab Inc., of Cincinnati, is moving into the plant in Natchez that had been run by Dynasteel. The plant will be known as Enersteel.

An announcement Tuesday from Mississippi Gov. Haley Barbour’s office says the plant will make fabricated steel-plate products, including storage tanks and pressure vessels for industrial process markets.

It also will make duct work and other air-quality control components for the power generation industry.

Jeff Hock, Enerfab’s president of process solutions and fabricated products, says the Natchez-Adams County Port on the Mississippi River will help the company ship and sell large fabricated products.

Pinnacle invests in Vietnam resort

Pinnacle Entertainment Inc., of Las Vegas, which is building a new casino and hotel in Baton Rouge, announced Tuesday the company has closed on a $95 million investment in a company that is developing a beachfront resort in Vietnam.

Pinnacle had announced in March an investment in Asian Coast Development Ltd., which owns the Ho Tram Strip beachfront resort 80 miles southeast of Ho Chi Minh City.

Pinnacle’s investment gives it 26 percent of Asian Coast Development and proportional representation on the company’s board of directors.

Pinnacle has a management agreement that runs through 2058 at a planned second Ho Tram Strip resort.

Pinnacle expects to complete the L’Auberge Casino & Hotel in Baton Rouge in summer 2012.
