Pile leg inertia reducing mechanism of offshore platform and offshore platform

ZHAO YONGBIN

The invention relates to the technical field of ocean engineering, and discloses a spud leg inertia reducing mechanism of an offshore platform and the offshore platform, the spud leg inertia reducing mechanism comprises a connecting cross brace, a connecting stand column and a vibration reduction component, the connecting cross brace is fixedly connected between adjacent spud legs, and the connecting stand column is fixedly connected with the vibration reduction component; the connecting stand columns are fixedly connected between the connecting cross braces and a platform body of the offshore platform. According to the spud leg inertia reducing and removing mechanism of the offshore platform and the offshore platform, the connecting cross braces are arranged between the adjacent spud legs, and the connecting stand columns are arranged between the connecting cross braces and the platform body of the offshore platform, so that temporary supporting structures are additionally arranged for the spud legs in the atrocious weather environment; swing of each pile leg is limited, inertia force of the pile legs is partially dispersed and acts on a platform body, the strength of a pile leg lifting structure is effectively improved, the phenomena of pile leg swing and local stress concentration of a pile fixing chamber are relieved or eliminated, and the bearing capacity of a foundation is improved.

本发明涉及海洋工程技术领域，且公开了一种海上平台的桩腿惯性减除机构及海上平台，包括连接横撑、连接立柱和减振部件，其中，所述连接横撑固定连接于相邻桩腿之间，所述连接立柱固定连接于所述连接横撑和所述海上平台的平台主体之间。该海上平台的桩腿惯性减除机构及海上平台，通过在相邻桩腿之间设置连接横撑，在连接横撑和海上平台的平台主体之间设置连接立柱，以在恶劣气候环境下为桩腿增加临时的支撑结构，其使得各桩腿的摇摆受到限制、桩腿的惯性力部分分散作用至平台主体，有效提高了桩腿升降结构的强度，减轻或消除了桩腿摇摆和固桩室局部应力集中现象的发生，提高了地基承载能。
