SNAME SAN DIEGO SECTION MEETS: The regular monthly meeting of the San Diego

Section of The Society of Naval Architects and Marine Engineers was held at the San

Diego Yacht Club on November 18, 1970. Following dinner, a technical paper entitled "Explosion Bonded Materials for Marine Structural Applications" was presented by

Charles R. McKenney and John G. Banker of DuPont De Nemours and Company, Inc.

The paper, backed up by slides, discussed the problems and applications for marine use of explosion bonded material. This method of bonding aluminum to steel proved to be of great interest to the attending members and their guests. A question and answer period was conducted afterward by Mr. McKenney and Mr. Banker. Pictured at the meeting, from left to right: Thomas S. Hand, Jr., vice chairman; C. Sinclair, chairman;

John G. Banker, speaker, Charles R. McKenney, speaker; David Rodger, papers chair- man, and G.A. Uberti, secretary-treasurer.

Bethlehem Beaumont Shipyard Launches 31,000-Dwt Unmanned Oceangoing Barge

The Ocean 250 slides down the ways of Bethlehem Steel's Beaumont, Texas, shipyard.

Two similar barges for Interstate Marine are on order at the Bethlehem yard.

What is believed to be the largest unmanned oceangoing tank barge ev- er constructed was launched on No- vember 20 by Bethlehem Steel Corpo- ration's Beaumont yard.

Named the Ocean 250, the huge steel barge was designed by George

Drake Jr., naval architect of Port

Washington, N.Y., and is owned by

Interstate Marine Transport Com- pany of Philadelphia, Pa.

The Ocean 250 has a deadweight of 31,000 long tons, or about twice that of the conventional T-2 tanker, the World War II standard. The largest tank barge heretofore con- structed according to available rec- ords was a 30,000 tonner.

Overall length of the Ocean 250 is 546 feet, breadth 85 feet, and depth 40 feet. It has a capacity of 255,000 barrels at a draft of 32 feet.

A 40-foot-deep notch is provided at the stern of the barge together with adjustable skegs to permit either tow- ing or pushing.

According to Interstate Marine

Transport, the big barge will normal- ly operate out of Marcus Hook, Pa., carrying refined petroleum products for the British Petroleum Company and serving Portland, Maine, Provi- dence, R.I., Boston, and New York

City.

Classed by the American Bureau of Shipping as an A-l Tank Barge,

Ocean Service, Unmanned, the Ocean 250 is also certified by the United

States Coast Guard for grade A Pe- troleum Products, Oceangoing Serv- ice.

Bethlehem Steel's Beaumont Yard has two similar huge barges on order for Interstate Marine Transport and another tank barge, almost as large, is on order for Sabine Towing and

Transportation Co., Inc., of Port Ar- thur, Texas. The Sabine Towing Co. is a subsidiary of Chromalloy Amer- ica Corporation.

The Ocean 250 has four 4500-

GPM deep-well pumps with GM die- sel drives serving 12 epoxy coated tanks. A hydraulic power system will handle the anchor windlass, hose booms port and starboard, eight mooring winches and five capstans for line handling.

Each cargo pump engine is pro- tected by weatherproof enclosures.

The electric generators and hydraulic power unit are enclosed in a small en- gine house. An air-conditioned office is also provided.
