Abstract：The sand compaction pile ship is a core equipment of sand compaction pile at sea. It is equipped with a large
number of processes equipment and advanced construction management system. During the construction process，the system
indicates piling works and records the parameter of the device in real-time. The data will serve as the basis for the quality
management of sand pile. Using the construction management system to control the key steps for making piles，it has very
important significance for assuring the quality of compaction sand pile.
