The invention discloses a hoisting method of an offshore crane. The method comprises the following steps that three hoisting points which are not located in the same plane are randomly taken, and thegravity center of a base is solved; hoisting points of hoisting are determined; lifting lugs are connected to the lifting points; steel wire ropes of the crane are connected with the lifting lugs to realize lifting of the base; a rotating platform assembly is hoisted; three hoisting points which are not located in the same plane are randomly taken, the gravity center of the rotating platform assembly is solved, and the hoisting points for hoisting are determined; a lifting lug is connected to the lifting point of a left side connecting lug; steel wire ropes of the crane are connected with thelifting points on the lifting lug on the left side and a right side connecting lug to lift the base; a tripod is hoisted, three hoisting points which are not located in the same plane are taken randomly, and the gravity center of the tripod is obtained; hoisting points of hoisting are determined; steel wire ropes are connected with the top end hoisting point and the lower hoisting point, and the upper ends of all the steel wire ropes are gathered and connected to the crane, and the crane is used for realizing hoisting; and a crane jib is hoisted. The method has the advantages that selection ofthe hoisting points of crane components is accurate and convenient, and the stress of the components is reasonable during hoisting.
