Semi-submersible type ocean nuclear power platform suitable for deep sea

Abstract

The invention relates to a semi-submersible type ocean nuclear power platform suitable for the deep sea. The platform comprises a superstructure, a deck box, small water plane uprights, a lower demihull and mooring devices. The platform is characterized in that the superstructure is located on the deck box, the small water plane uprights are each of a cylindrical structure, the deck box communicates with the lower demihull through the more than one small water plane uprights, the mooring devices are deep sea anchoring devices arranged on the deck box or / and dynamic positioning devices arrangedat the bottom of the lower demihull, a reactor room, a steam turbine generator cabin and a sea water desalination equipment cabin are arranged in the lower demihull, and more than one water ballast tanks are arranged in each of the small water plane uprights and the lower demihull. A single-demihull semi-submersible type platform type and small water plane upright structures are adopted, the lower demihull is submerged in the operation process, work and living zones are away from the reactor room, equipment operates stably, and personnel are safe and feel comfortable. The semi-submersible type ocean nuclear power platform is simple in structure, easy to construct and convenient to expand.

Description

technical field [0001] The invention relates to marine engineering, in particular to a semi-submersible marine nuclear power platform suitable for deep sea. Background technique [0002] The marine nuclear power platform is an organic combination of marine engineering and nuclear energy engineering. It has the characteristics of long charging cycle, good mobility, energy saving and environmental protection, and can provide reliable energy guarantee for marine resource development and island and reef construction. In practice, it is often necessary to move from one job site to another. [0003] Existing nuclear power supply platforms such as the USS "Sturgis" and Russia's "Lomonosov" are all developed and designed for areas with moderate environmental conditions such as nearshores and ports. The form of the ship has a large motion response when disturbed by waves, and it relies on anchor chains, cables and other devices to anchor in the wharf and harbor basin. energy demand...

Problems solved by technology

[0003] Existing nuclear energy supply platforms such as the USS "Sturgis" and Russia's "Lomonosov" are all developed and designed for areas with moderate environmental conditions such as nearshores and ports. The form of the ship has a large motion response when disturbed by waves, and it relies on anchor chains, cables and other devices to anchor in the wharf and harbor basin. energy demand

[0004] CN201510415414.5 The reactor is arranged between the lower sheet body and the deck box, and the suction anchor is used to operate in the diving sea area. However, due to the close distance between the personnel and the reactor device, it is easy to suffer from radioactive hazards and the psychological pressure of the operators is high

In addition, it is difficult to fully submerge the reactor below the waterline during its operation, which is not conducive to making full use of the core submersion technology to ensure the safety of the reactor under extreme working conditions

At the same time, no consideration is given to reserving the carrying space for future functional requirements modules, and subsequent expansion of functions and transformation are more difficult

[0005] The existing semi-submersible marine nuclear power platform has absorbed the advantages of the semi-submersible drilling platform, which is suitable for deep-sea positioning and has a small water plane, which is less affected by wave disturbance and motion response. However, its lower part is small, which is not conducive to the layout of nuclear power devices and its protective compartment
