Pittsburgh-Des Moines Orders

Large Quantity Of Aluminum

For LNG Ship And Land Use

Aluminum 'Company of America has an- nounced receipt of orders for more than 33 million pounds of aluminum plate, extrusions and welding wire to foe used in tanks for land- based storage of liquefied natural gas and for

LNG supertankers.

The orders, for two unrelated LNG projects, came from Pittsburgh-Des Moines Steel Co.

PDM will build four storage tanks for the

Cove Point (Md.) Import Terminal, and 20 storage vessels for Quincy Shipbuilding Divi- sion of General Dynamics for oceangoing tank- ers. The orders bring to approximately 100 million pounds Alcoa's commercial plate back- log for LNG applications.

The Cove Point Terminal, expected to be completed in late 1976, is the world's largest aluminum land-based LNG project. Housing four giant storage tanks, each with a capacity of 375,000 barrels, the 1,022-acre terminal will have a design capacity sufficient to meet the annual requirements of more than 1,000,000 homes.

Each of the double-wall storage tanks will measure approximately 141 feet (43 meters) high by nearly 169 feet (52 meters) in diame- ter—more than half the length of a football field. The inner shell will be built from 15 by 31-foot aluminum plates ranging from near- ly two inches thick at ground level to ap- proximately one-half inch at the top. The outer shell will foe carbon steel.

The terminal will receive the LNG equiva- lent of one billion cubic feet of gas each day from a fleet of specially designed supertankers.

The tankers will travel nearly 4,000 miles from

Algeria. An El Paso Natural Gas Co. subsid- iary will purchase and ship the LNG to Cove

Point, which is being constructed by a sub- sidiary of the Columbia 'Gas System, and will be owned jointly by Columbia and a Consoli- dated Natural Gas Company subsidiary.

The 20 LNG storage vessel for oceangoing supertankers will be constructed at PDM's new Charleston, S.'C., operations. Alcoa will supply flat and machined plate shapes, extru- sions and welding wire. Each sphere will have a capacity of 25,000 cubic meters and an inside diameter of approximately 120 feet (36.5 me- ters).

Each tanker will contain five spheres with a gross ship capacity of 125.000 cubic meters.

The tankers will be built at Ouincy, Mass., for Cherokee Shipping Corp., for charter to subsidiaries of Energy Transportation Corp., a recently formed United States-flag vessel fleet.

THIRD IN A SERIES FROM HALTER: Halter Marine

Fabricators of Moss Point, Miss., recently delivered the motor vessel Khair-Ed-Din to Euro-Pirates International,

Inc. of New Orleans, La. Khair-Ed-Din is the third in a series of vessels being built for Charlie Slater, better known as Champagne Charlie, a New Orleans hotel own- er (French Quarter Inn). The 176-foot by 38-foot by 14- foot vessel is certified by the American Bureau of Ship- ping for A-l and Full Ocean, and also by the U.S. Coast

Guard. Upon delivery, the Khair-Ed-Din is scheduled to service the offshore oil and mineral industry off the coast of Brazil.

Mainland China Places Order

Worth $2 Million For Rucker

Petroleum Drilling Equipment

The People's Republic of China has ordered petroleum drilling controls and blowout pre- venters valued at approximately $2 million from The Rucker Company, a major producer of petroleum drilling and well production equipment.

Company officials said the order is believed to foe the first received by a U.S. company for petroleum drilling equipment from the Peo- ple's Republic since President Nixon reduced trade barriers between the two nations.

The order was received through the China

National Machinery Import and Export Cor- poration following a visit of Rucker officials to China, and is for 20 land blowout preventer stacks. This equipment is used to control well bore pressure during drilling operations, and is a safety and environmental protection con- trol preventing blowouts if high pressure pock- ets of gas or fluid are encountered.

Rucker Shaffer Division, located in Hous- ton, Texas, will manufacture the equipment for delivery in the latter half of this year. Both ram and spherical preventers with high pres- sure gate valves will foe supplied. Four will be specially treated for high toxic, sour gas drilling conditions and will be equipped with rotating blowout preventers.

Rucker is the only major producer of all three basic ram, spherical, and rotating blow- out preventers, and supplies them singly or in various types of combinations to suit a broad range of special requirements. The company's petroleum group divisions operate major fa- cilities in Houston and in California, and manufacture special tools and equipment for deep high-pressure petroleum drilling and well production.
