The M/V National Energy, flagship of National Marine Serv- ice Incorporated towboat fleet, was christened recently at dock- side ceremonies in New Orleans,

La.

As a mover of bulk petroleum and chemical products, the new towboat will primarily serve the

Gulf Intracoastal and lower Mis- sissippi River System. The vessel measures 140 by 42 by 11 feet, and is powered by two 16-cylinder

General Motors EMD turbo- charged diesel engines. Engine performance is monitored by Na- tional Marine's TUGMONITOR system. It is equipped with the company's BilgeMaster oil-water separator and energy recovery system.

The 5,600-horsepower towboat was built by Dravo Corporation's

Engineering Works Division and launched from its Neville Island shipyard near Pittsburgh, Pa., (see MARITIME REPORTER/

Engineering News, December 1, 1979, issue, cover story).

According to David A. Wright, president of National Marine Serv- ice, the name National Energy emphasizes the energy efficiency of the waterway industry and the company's role in moving the na- tion's energy resources.
