the Air Deliverable Antipollution Transfer System (ADAPTS], it 

 was developed to provide an emergency method for removing cargo 

 oil from tanks still intact after the accident. The pumping capability 

 of ADAPTS has been successfully used in several pollution 

 incidents and has prevented the discharge of large volumes of 

 pollutants into the waters. Testing of the flexible bag into which the 

 oil is pumped will continue in 1974. 



Development of a system to restrict the spread of spilled oil and to 

 facilitate recovery has been completed. The general design goal for a 

 high seas containment barrier is the ability to effectively contain oil 

 in 20-mph winds and 5-foot seas and survive in up to 40-mph winds 

 and 10-foot seas. The barrier is a fence type with a draft of 27 inches 

 and a freeboard of 21 inches. Buoyancy is provided by inflated 

 horizontal pillows approximately 14 inches in diameter and 6 feet 

 long. The pillows are inserted perpendicular to the barrier fabric at 

 56-inch intervals. An external tension line, bridled to the barrier, is 

 the primary strength member of the barrier. The test program has 

 shown that the barrier can meet the design criteria but is limited to 

 containment of oil in currents of less than 1 knot. Effort is continuing 

 to develop a parachute delivery system and deployment technique 

 for the barrier. Procurement of barrier sections for delivery to the 

 site by ship has been initiated with delivery anticipated to 

 commence during the spring of 1974. 



Development of high recovery rate, open ocean oil harvesting 

 equipment is now at the prototype design and construction stage. 

 The design goals for this equipment are to recover 2,000 gallons per 

 minute of oil in 20-mph winds and 5-foot seas and to survive 40-mph 

 winds and 10-foot seas. This equipment is to be air transportable but 

 not deliverable by parachute. Use of both a wave conforming weir 

 and rotating disc drum is being investigated. The wave conforming 

 weir consists of two parallel oil barriers connected with a flexible 

 curtain to form a basin. The leading barrier is slotted at the water 

 line to permit oil to pass through and collect in the basin. The 

 secondary barrier is also fitted with a weir that is connected to an oil 

 transfer pump suction. The disc drum uses the principle that oil 

 preferentially wets metal surfaces. As the disc drum is rotated into 

 the oil slick, oil attaches to its metal surfaces. The oil is then scraped 

 from the drum and collected in a trough for subsequent transfer to a 

 storage container. Completion of testing of the prototype system is 

 "planned for the spring of 1974. Procurement action will be initiated 

 at the completion of development. 



As the operational systems are delivered to the National Strike 

 Force, they will be at the major port complexes of the United States. 

 The Strike Force will maintain the equipment in a state of readiness 

 to allow immediate deployment at the scene of a major discharge.
