Atlantic Marine Delivers

New Pusher Tug To Belcher

Atlantic Marine, Inc., located in the Jack- sonville, Fla., suburib of Fort George Island at the intersection of the St. Johns River and the Intracoastal Waterway, recently delivered the 70-foot pusher tug E.-N. Belcher Jr.

The boat is named after the late chairman and president of the owner, Belcher Oil Co. of Miami. The tug will be based in Fort

Myers and used in oil deliveries on the Okee- chobee Waterway and Florida's lower west coast. LJC. Morris, Belcher's towing opera- tions manager, selected the shallow-draft push- er tug design for more flotation and power in the shallow waters of the Caloosahatchee

River connecting Lake Okeechobee with the

Gulf of Mexico.

The tug is 70 feet long, with a 27-foot beam and a depth of 9.5 feet. Power is supplied by two Caterpillar D-379 engines with a total get the? best f get TURECAMO on your side

ASNE Delaware Valley

Propeller Profiler

A paper on the recently installed propeller profiler at the Philadelphia Naval Base was presented at a meeting of the Delaware Valley

Section of The American Society of Naval

Engineers on February 20, 1974. Comdr.

James K. Williams, USN, author, read the paper titled "Automated Propeller Profiler," and Capt. F. Warne Gooch, USN (ret.), was coordinator. Over 30 members attended the session.

The new propeller profiler is an automated, numerically controlled machine tool with five axis motion. It uses both side mill and end mill cutters to produce accurately contoured propellers up to 15 feet finished diameter from work pieces weighing up to 25 tons. Machine operation is controlled through the medium of punched tape containing the set of instruc- tions for a particular portion of the work. The instruction sets are generated on an IBM 360

Computing System using an extended version of the APT (Automatically Programmed

Tools) Program originally developed by M.I.T. and A.I.A., and currently administered by the

Illinois Institute of Technology Research In- stitute. 12
