Study On Container Ships' Evacuation Of Last Minute In Case Of Typhoon For Ningbo Port

Along with the globalization of the international economic trade and the economic integration,it gives steady,lasting and fast development to our national economy.And the booming of foreign trade amount further brings the prosperity for shipping market.Ningbo Port is a multi-purpose,comprehensive,modern and deep-water port integrated with inner harbor,estuary harbor and sea port.The number of existing operational berths is 305,in which 60 ones are for more than 10 thousand tons.The greatest cruel oil terminal is for 250 thousand tons,while the ore receiving terminal is for 200 thousand tons(also available for 300 thousand tons);there are also the international container ship berth of the sixth generation and the 50 thousand-ton liquid chemical product berth:and all the berths above has opened up to more than 600 ports of more than 100 countries and regions.As the container throughput and the route intensity of foreign container trade are growing rapidly,Ningbo Port has become the main container trade port.Ningbo Port enjoys a favorable trend of growing in operation,and the throughput of containers in 2007 is 9349.7 thousand TEU,year on year growth of 32.28%,ranking the fourth of all the mainland ports.For 10 consecutive years,it has kept a growing rate of more than 30%.The contradiction between the rapid growing of throughput and the fixed receiving capacity is becoming increasingly acute.In view of the problem above,according to the anti-typhoon supervision and administration regulation of Ningbo Port,this text analysed the hydrological data, climatological data,distribution of the container ship berths,typhoon shelter anchorage and the typhoons which can affect Ningbo waters.Taking into account of the workable maximum wind speed,wave height,the maximum wind force which can be stood by port based container cranes,wind resistance level of the container ship,the characteristics of container ship's maneuvering in heavy surf conditions,the typhoon central position,expecting landing spot,typhoon central force,10 Beau and 7 Beau of wind circle,the track and speed of typhoon,the time needed for container ship's emergency evacuation,the ship evacuation of last minute plan due to typhoon was raised.With this plan,when typhoon is coming,by the promise of guarantee of safe evacuation,the operation period of container ship can be greatly reduced,bringing along with enormous economic benefit,which makes practical meaning for the container ship growing throughput of Ningbo Port.
