General Electric Credit

Buys Its Eleventh Tanker

General Electric Credit Corpo- ration (GECC) announced it has acquired for $89,980,000 the 165,- 000-dwt Thompson Pass, a new crude carrier to transport Alaska oil to the U.S.

The vessel will be time char- tered to SPC Shipping, Inc., a

Simplicity is the key to the Demco packaged sewage treatment plant.

And your key to low maintenance operation that is fast, effective, reliable and economical.

Simple Low Maintenance Opera- tion. Raw sewage enters the plant and passes through aeration cham- bers by gravity. What could be more simple than that? There are no pumps or intricate mechanisms to clog or break down. Wastes are reduced by aeration and consumed by an exclu- sive mixture of bacteria-enzymes.

Final disinfection is by dry soluble chlorine tablets.

Fast. Special bacteria-enzymes accelerate degradation and maintain a viable biology. In a day's operation, the Demco system will process as subsidiary of The Standard Oil

Company of Ohio (Sohio). It will be operated for Sohio by IOT

Corporation.

Built at Avondale Shipyards in

New Orleans, La., the 906-foot- long vessel can carry up to 1.2 million barrels of oil. It sailed

August 25 for Cape Horn, and is expected to arrive at Valdez,

Alaska, about October 25. much as 25% more sewage than competitive designs. Standard

Demco units process from 325 to 12,500 GPD. Larger systems are available for special applications.

Effective. Demco system design treats all degradable wastes includ- ing difficult materials like paper, grease, oil, detergents and garbage processed through a disposal with impressive results. When operated using recommended procedures,

Demco sewage treatment plants will remove 85-95% of BOD and sus- pended solids. The effluent contains a minimum chlorine residual of 1 mg./ liter and 1,000 or less coliform bacteria per 100 milliliters.

Reliable. Demco sewage treatment plants perform. Performance that

GECC owns 10 other tankers totaling 1,378,500-dwt with a first cost of nearly $644 million.

The Thompson Pass was ac- quired August 23 under a lever- aged leasing arrangement where- by GECC invests a portion of the purchase price in a trust which borrows the balance of the ves- sel's cost from long-term lenders.

A spokesman for the Stamford, has earned National Sanitation

Foundation certification (Standard 23).

Demco plants are also certified by the U.S. Coast Guard, and meet or exceed U.S. Geological Survey and anticipated IMCO effluent requirements.

Reduction of BOD and suspended solids below 10PPM is common with the addition of the Demco Dual

Media Tertiary Filter downstream of the basic plant. This quality effluent exceeds all published EPA require- ments for land and offshore sewage discharge.

Conn.-based financial arm of the

General Electric Company said that although the international tanker market is currently de- pressed, the demand has been strong for vessels to be used to carry Alaskan crude. Tankers op- erating between US. ports must be American-flag vessels; this has eliminated the bulk of idle world- wide tanker tonnage from con- sideration.

The Thompson Pass is the third tanker GECC has purchased for long-term charter to Sohio. In the last year, GECC also acquired under leveraged lease arrange- ments two 165,000-dwt sister- ships to the Thompson Pass—the

Atigun Pass and the Keystone

Canyon. Both were built at Avon- dale.

GECC acquired sole ownership of the Atigun Pass and is the joint owner of the Keystone Can- yon with Bankers Trust Co.

The new vessel brings the Sohio charter fleet to more than 30 tankers. Sohio owns more than 50 percent of Alaska North Slope crude and one-third of the Trans-

Alaska Pipeline System.

Worthington Receives $2.5-Million Order

For Navy Compressors

The U.S. Naval Sea Systems

Command has ordered 22 marine compressors worth over $2.5 mil- lion from the Process and Gas

Division of Worthington Com- pressors, Inc., as part of a fleet modernization program.

The 50-horsepower, high-pres- sure, oil-free units will replace existing equipment aboard older surface ships. Delivery will be during the first six months of 1980 to various U.S. Navy sup- ply depots across the country.

Navy shipboard compressors are used for missile launchings, pumping air banks on tenders, etc.
