摘　　要：带有沉垫的自升式平台是较为特殊的一种平台,而其稳性分析相比常规的桩靴式自升式平台也有所不同。文章研究了一型沉垫自升式风电平台的拖航稳性和沉浮稳性,在破舱稳性计算中增加了对于空舱未设置舱底水系统时的特殊考虑,按照规范对坐底式平台的要求校核其沉浮稳性,并提出平台沉浮过程中重心变化的便捷计算方法,可以为类似平台的稳性计算提供借鉴。The self-elevating unit with mat is a special kind of unit, and its stability analysis is different from traditional self-elevating unit with spudcan. The article studies the towing stability and sinking stability of a type of self-elevating wind turbine installation unit with mat. A special consideration is added to the calculation of the damage stability when there is no bilge system in the void tank. The sinking stability is checked according to the requirements of the code for sitting type unit, and a convenient calculation method for the change of center of gravity during sinking is proposed, which can offer reference for the stability calculation of similar units.
