Abstract: To address the issues—high construction costs, limited flexibility, and difficulty in meeting the maintenance demands of large naval vessels such as aircraft carriers—associated with traditional ultra-large floating docks, this paper proposes a modular, self-propelled, multi-functional offshore floating-base structure based on the concept of very large floating structures (VLFS). This platform consists of multiple small floating dock modules, each equipped with its own lifting, self-propulsion and dynamic-positioning systems. These modules can be flexibly combined according to mission requirements to form an ultra-large floating operation platform with comprehensive support capabilities. This paper elaborates on its overall architecture, buoyancy design, power configuration, ship guidance system, and structural connection scheme. Furthermore, its structural safety and operational feasibility are validated by means of hydroelastic-response analysis and transverse-strength assessment. This design provides an important reference for the future engineering implementation and educational application of mobile offshore bases.
