According to an adaptive modification project for enlarging the footings of a jack-up drilling plat-form,this paper analyzed the pile-driving system modification and piping system arrangement of the ship after en-larging the footings,and summarized the theory and requirements for the design of the pile-driving system.By using pile driving system simulation software to optimize the position of nozzles,this paper finally formulated the optimal operation program.
