Due to the limited anchorage waters,we study a new mooring way using portal framed spud for fixing floating pier in Zhuanghe port which a group of portal framed spuds are set both in bow and stern of steel ship.All spuds can work together under various operating conditions.The mooring system can effectively restrain horizontal displacement and reduce project cost.The steel floating boxes are placed at both ends of steel ship,thus the ship that can be convenient installing and maintaining.
