摘　　要：钻井船通常在船坞建造，但受船坞资源可获得性和建造工期等诸多因素影响，“海洋石油921／922”两艘200英尺自升式钻井船选择在青岛场地3号滑道上建造。在码头建造完工后，先拖拉装船到半潜驳，再以半潜方式下水。2010年5月，“海洋石油921／922”两艘钻井船相继在青岛场地码头前45m的港池由半潜驳“德浮2号”下水。通过介绍钻井船半潜下水的关键技术，为以后类似工程提供借鉴和参考。Jack-up is constructed in dock usually, but for the influence of limited dock and delivery time, No.3 skidway of Qingdao yard selected as the construction site of two 200 feet self-elevation jack-ups, HYSY921 and HYSY922, and launch them into sea by semi-submergible barge DEFU2 after pulling them onto barge. HYSY921 and HYSY 922 have been launched successful in the pre-dredged area, 45m away from the quay in May 2010. Now the semi-submerge technology of this project presented for reference.
