Background
In nuclear power plants, some popular commercial land heap-type primary loop equipment is of loop type, uses long primary pipe connections, the primary equipment supports are split supports for each piece of equipment, and design benchmarks are fully considered in terms of land operating conditions. In the land environment, the primary equipment of the primary loop keeps static for a long time under the normal working condition, and only under the accident working condition (such as the break of the primary pipe and earthquake), the primary equipment is impacted and is subjected to instantaneous lateral or vertical inertia force. The land heap main plant support is therefore to meet the demand for releasing thermal displacements, with a large degree of freedom and lateral support only briefly effective in accident conditions. The marine environment load is complex, under the condition that the marine condition continuously and periodically swings and inclines, each main device can generate larger continuous alternating inertial load in the horizontal direction and the vertical direction, and the size of the main device is in direct proportion to the mass of the device.

Thus, existing land pile-up main equipment support foundations are not suitable for ocean platforms.
