IHC Holland and a Dutch firm of contractors have designed the Small Agt. a vessel capable of dealing effectively with major oil spills in open water. The basic vessel design is that of a trailing-suction hopper dreger with a hopper capacity of approximately 5,00 sq m (5 million L or greater than 1 million gal). The vessel will be used to maintain the depth of navigational channels along the Dutch coast when not in use in an oil disaster. When an oil disaster is reported, the vessel ceases dredging, empties its hopper, and moves to the site of the spill. Special arems, which are angled forward, are lowered onto th surface, and clearance of the oil begins. With each sweep, a 50-yd-wide path is cleared. The oil is conducted to the "armpits" of the port and starboard collectors, where it is drawn into centrifugal pumps and transported to the hopper. The oil is separated from the water by centrifuges and either stored in tanks on board or transferred to a tanker alongside. Since this method is faster than any in use, the washing up of oil on beaches, and further, or other, pollution of the environment can be prevented.
