针对自升式平台在多样化功能应用中面临的通用性不足的问题，以实现平台功能通用化为目标，开发一种模块化多功能平台。基于“基型+变型”的设计思路，给出平台模块化布置方案，包括设计指标、主尺度、基础平台布置、功能模块布置、装载重量平衡等。选取电力负荷、稳性、桩腿强度等关键指标进行冗余分析，考虑平台二阶耦合效应，完成全方位动态载荷计算，基于强度校核结果进行平台全局设计及方案验证并给出设计建议。研究结果表明，关键指标冗余度大于0，桩腿利用率小于1，整体和局部结构强度均满足规范要求，验证了结构设计的合理性。研究成果可为我国海工装备模块化开发提供参考。
Addressing the limited versatility of jack-up platforms in various functional applications, this study introduces a novel modular multifunctional jack-up offshore platform designed to enhance the platform's functional versatility. Based on the design principle of “base+variant”, the study presents a modular arrangement scheme for the platform, which includes the design index, main scale, base platform arrangement, functional module arrangement, and load weight balance. Key indices such as electric load, stability, and pile leg strength are selected for redundancy analysis. The second-order coupling effect of the platform is considered, and a comprehensive dynamic load calculation is performed. Based on the results of the strength calibration, the global design and the verification of the scheme are conducted. The research findings indicate that the redundancy of key indices is greater than zero, the utilization rate of pile legs is less than one, the overall and local structural strength complies with specification requirements, and the reasonableness of the structural design is confirmed. These research results can serve as a reference for the modular development of offshore equipment.
