Study on Mechanical Calculation and Analysis of One Ship-Type FNPP

In this paper, one ship-type Floating Nuclear Power Plant（FNPP）, which is fixed by multi-point anchor chain, was studied. The loads applied on FNPP was calculated and analyzed under various kinds of external forces, such as wind, wave, current and ice, and under the sea conditions encountered in one hundred year and two hundred year. The results show that the chain does not break under the worst sea condition. The maximum tension and the maximum deviation of the chains meet the requirement, and the safety factor is within the maximum limit. Analysis results show that the multi-point anchoring can satisfy the operational requirements of of a floating nuclear power plant.
