    摘要:

    自升式海洋牧场综合平台是一种新型海洋牧场管护设备,可用于海洋牧场管理和海洋环境监测。以自升式海洋牧场综合平台为研究对象,对平台抗倾覆性能进行分析。计算了平台的倾覆力矩和回复力矩,分析了抗倾覆安全系数,并校核了桩腿强度。所涉及的倾覆力矩载荷包括风载荷、波流载荷、P-Δ载荷和DAF载荷,回复力矩载荷包括空船重量、桩腿桩靴重量以及桩腿浮力。计算结果表明本平台抗倾覆稳性满足规范要求。计算结果可为自升式平台环境载荷计算和抗倾覆性能分析提供参考。

    Abstract:

    Self-elevating marine ranch platform is a new type of marine ranch managing equipment, which can be used for marine ranch management and environmental monitoring. Regarding a self-elevating marine ranch platform as the research object, we calculated the overturning moment and restoring moment, analyzed the overturning safety factor, and we also checked the strength of pile legs. Overturning moment loads include wind load, wave current load, P- Δ Load and DAF load. Recovery moment loads include the weight of empty ship, the weight of pile legs and pile shoes, and the buoyancy of pile legs. The results show that the overturning stability of this platform meets the standard requirement. The results can provide a reference for the environmental loads calculation and the overturning stability analysis of self-elevating platforms.
