Avondale Shipyards, Inc. of New Orleans recently ordered three cargo control systems from Megasystems, Inc. of Boca Raton, Fla., and Cleveland, Ohio, for installation in three 43,000-dwt product carriers ordered earlier this year by Exxon Company U.S.A. of Houston, Texas. With a total price tag of $300 million, these ships will be fitted with the best and most sophisticated equipment available in the world today. They will be powered by 17,000-bhp diesel engines.

The cargo control consoles will be approximately 30 feet in length, and will feature full mimic displays as well as controls for each of the cargo tanks. Delivery of these ships is scheduled for 1983 and 1984.
