摘　　要：自升式施工平台作为离岸工程的重要辅助装备,其外形上具备常规船舶的特点,通过升降装置和桩腿将船体抬离水面,工作时不受海水运动的影响,保证了海上作业的稳定性和安全性,可在相对恶劣的海况下持续作业,扩大作业窗口期。该文结合某型自升式碎石桩施工平台,对轮机系统的设计进行分析探讨,为该类施工平台的设计提供建设性的意见和参考。As an important auxiliary equipment for the offshore engineering,the jack-up platform has the characteristics of the conventional ships in appearance.The hull can be lifted off the water surface by lifting devices and pile legs.The operation of the jack-up platform is therefore not affected by the seawater movement,ensuring the stability and safety of the offshore operations.It can operate continuously under the relatively rough seas,and expand the operation window phase.The design of the machinery system of the jack-up gravel pile construction platform is analyzed and discussed to provide suggestion and references for the design of this kind of construction platform.
