Operation timed assigns 5 mooring, main anchor cable length should be 200 to 300 meters, the anchor tail length should be 200 to 300 meters, high velocity of poor quality long timely. The edge should be thrown in mooring line outside the 100 meters. Near point positioning, anchored procedures and chain bucket ship basically the same.
