Huahai - Oil Trawl

As for crude oils of high viscosity, which are condensed into solid blocks at room temperature, floating or shifting in waters, and are difficult to be retrieved by a mechanical recovery device. A better recovery can be made with the oil trawl. The oil trawl is mainly composed of a frame, buoy, main net, dragnet and nylon fabric bag. The dragnet is detachable from the main net. When the net is full, it can be replaced with a new one.
