下水工作船是专用于船舶和海上设施下水的特殊船舶。本文针对16000吨举力下水工作船，从船体结构设计和结构强度两方面进行分析和研究。船体结构设计的研究对比了驳型和坞型2种不同结构形式对船体结构设计和强度的影响。结构强度的分析运用全船有限元计算方法，计算了装船工况和沉浮工况下的全船结构强度。相关研究结果对今后下水工作船的设计有一定的参考价值。
Launching work vessel is a special vessel designed for launching ships or offshore installations. This paper focused on the research of16000tlc launching work vessel. Investigations were carried out form two aspects, including structural design and strength analysis. As for structural design, different between barge type and dock type were proposed. Global finite element model was constructed to analyze the strength check issue, which concentrated on loading condition and lifting condition. The conclusions were of guiding significance to the design of launching work vessel.
