摘要
针对施工硬质土时绞吸船横移操作难以控制的问题,验证更换七臂绞刀后“新海豚”轮在滨海LNG项目疏浚施工中的生产率与稳定性,以水下泵吸入真空为研究对象,提出基于Xbar-R控制图的绞吸挖泥船横移挖泥操作参数范围的设定方法,并将测算结果应用于后续工程实际中。结果表明,该方法能够科学、直观地帮助操作人员掌控最佳参数范围,进而提高船舶生产率。
Aiming at the problem that it is difficult to control the transverse operation of cutter suction dredger in the construction of hard soil,the productivity and stability of"New Dolphin"ship in the dredging construction of coastal LNG project after replacing the seven-arm cutter are verified.Taking the suction vacuum of underwater pump as the research object,the setting method of the operating parameter range of cutter suction dredger transverse dredging based on Xbar-R control chart is proposed,and the calculation results are applied to the subsequent engineering practice.The results show that this method can scientifically and intuitively help the operator to control the optimal parameter range,and then improve the ship productivity.
