The invention discloses a method for carrying out ballast tank strength test in a dock. The method comprises the following steps that in a dock stage, water is injected into a first batch of ballast tanks in the dock and a half ship for multiple times in stages until the first batch of ballast tanks reach a full tank state; strength test is performed on the first batch of ballast tanks; ballast water in the first batch of ballast tanks automatically flows and lighters into a second batch of ballast tanks until the liquid levels in the first batch of ballast tanks and the second batch of ballast tanks are equal; water is injected into the second batch of ballast tanks of the half ship until the ballast tanks are in a full-tank state, and strength test is performed on the second batch of ballast tanks; and water in the half ship and the dock is drained step by step for multiple times. According to the method, the ballast tank strength test is completed in advance to the dock stage, the starting node of work in a cargo hold can be moved forwards, the construction period of the ship is greatly shortened, and the construction efficiency of the ship is improved.

    本发明公开了一种在船坞内开展压载舱强度试验的方法,包括以下步骤:在船坞阶段,分阶段多次向船坞和半船内的第一批次压载舱内注水至第一批次压载舱达到满舱状态;对第一批次压载舱进行强度试验;第一批次压载舱内的压载水自流驳运至第二批次压载舱内直至两者舱内液位相等为止;向半船的第二批次压载舱内注水至满舱状态,对第二批次压载舱进行强度试验;多次逐步排干半船内和船坞内的水。本发明将压载舱强度试验提前至船坞阶段完成,能够将货舱内部工作的开工节点前移,大大缩短了船舶的建造周期,提高了船舶的建造效率。
