The invention provides a ship superstructure underwater hoisting method. The ship superstructure underwater hoisting method comprises the following steps that S1, the total weight of superstructure segments after closure is counted; s2, determining the model of the floating crane according to the total weight of the overbuilt subsections and the allowable lifting height of the floating crane; s3, according to the arrangement of the upper hook head of the floating crane, the distribution of hoisting points on the upper building subsection is designed; s4, designing a superstructure folding transfer platform according to the total weight of the folded superstructure sections and the lower enclosure wall diagram of the folding opening of the superstructure sections; s5, superstructure closure and fitting-out piece installation are carried out on the transfer platform; s6, the folded superstructure subsections are transferred to a ship unloading frame through a transfer platform; and S7, transferring the superstructure section to an outfitting wharf by using a floating crane, and folding the superstructure section with the main ship. According to the ship superstructure underwater hoisting method, the underwater period is not affected, the ship launching weight is greatly reduced, ship launching in winter becomes possible, the berth period is greatly shortened, the berth utilization rate is increased, and the ship underwater period is also greatly shortened.

    本发明提供了一种船舶上建水下吊装方法,包括以下步骤:S1.统计上建分段合拢后的总重量;S2.根据上建分段总重量和所允许的浮吊吊高确定浮吊型号;S3.根据浮吊上钩头的布置设计上建分段上的起吊吊点分布;S4.根据上建分段合拢后的总重量及上建分段的合拢口下围壁图设计上建合拢转运平台;S5.在上述转运平台上进行上建合拢及安装舾装件;S6.利用转运平台将合拢后的上建分段转运至卸船架处;S7.使用浮吊把上建分段转运至舾装码头与主船合拢。本发明的船舶上建水下吊装方法,不影响水下周期,船舶下水重量大大减减轻,使船舶冬天下水成为可能,大大缩短船台周期,提高了船台利用率,也使船舶水下周期大大缩短。
