Abstract

The invention discloses an offshore nuclear power platform with cylindrical foundation bodies. The offshore nuclear power platform comprises an upper platform, a lower hull, platform pile legs and a foundation, wherein the upper platform is arranged on the platform pile legs, the lower hull is arranged below the platform pile legs, matching equipment of a nuclear power plant is arranged on the upper platform, and a nuclear island is arranged in the lower hull; the foundation comprises the multiple cylindrical foundation bodies, and one end of each cylindrical foundation body is provided with a guide post; the lower hull is arranged on the foundation and connected with the foundation through the guide posts. The offshore nuclear power platform has the following advantages that offshore refueling can be achieved on the upper platform, refueling can be carried out after the platform floats, shifts and returns to a land base, and safety is improved; multiple small reactors can be installed in the lower hull, the nuclear island (the reactors) are arranged below the sea level surface and provided with a valve communicated with sea water, the sea water will enter the hull in emergency situations, and the safety of emergency working conditions is greatly improved. The offshore nuclear power platform can be installed automatically, is easy to discard and low in cost, has mobility and can serve multiple oil fields or oil field groups.

Description

technical field [0001] The invention relates to a cylindrical foundation offshore nuclear power platform, which belongs to the technical field of marine engineering. Background technique [0002] Offshore oil and gas development facilities usually provide power by self-generation, power supply by land grid through long-distance submarine cables, and interconnection of multiple platform power stations in regional oil fields. For example, the Bohai Oilfield mainly provides power for production facilities through self-generated power and the networking of multiple platform power stations in regional oilfields. [0003] With the continuous development of offshore oil development, we are faced with the contradiction between the rapid decline of associated gas in offshore oil fields and the rapid increase in power demand. Due to the serious shortage of self-produced associated fuel gas of the main platform, the fuel cost of exporting fuel gas is huge, or the burning of expensive ...
