Aerosol fire extinguishing system for offshore platforms

Abstract

The invention discloses an aerosol fire extinguishing system for offshore platforms. The aerosol fire extinguishing system is arranged in an electric room of an offshore platform and comprises a smoke detector, a heat detector, an aerosol fire extinguishing controller and an aerosol fire extinguisher, wherein both the smoke detector and the heat detector are connected with the aerosol fire extinguishing controller and the aerosol fire extinguishing controller is connected with the aerosol fire extinguisher. The aerosol fire extinguishing system for the offshore platforms, disclosed by the invention, has the advantages that the electric room can be effectively and rapidly protected; in the meantime, the using area of the platforms is effectively reduced; the platform structure is optimized; the platform structure weight is reduced; the daily equipment maintenance operation is reduced; while the platform safety is guaranteed and staff is prevented from suffering asphyxiation injury, the investment cost of simple unmanned platforms is greatly reduced and the aerosol fire extinguishing system more conforms to the design concept of the offshore simple unmanned platforms.

Description

technical field [0001] The invention relates to an aerosol fire extinguishing system for an offshore platform. Background technique [0002] In recent years, with the development and utilization of marginal oil fields by offshore oil, there are more and more simple unmanned wellhead platforms on the sea. Compared with conventional platforms, simple unmanned wellhead platforms have the following characteristics: 1. Higher automation requirements; 2. , Simple structure, small platform, light weight. Therefore, research on how to reduce the platform area and structural weight as much as possible on the premise of ensuring platform functions and safety has entered the platform design agenda. Currently, electrical rooms on offshore platforms mainly rely on gas fire extinguishing systems, and commonly used gas systems include carbon dioxide fire extinguishing systems and heptafluoropropane fire extinguishing systems. Among them, the carbon dioxide system has the safety feature o...

Problems solved by technology

Among them, the carbon dioxide system has the safety feature of causing suffocation and death to the staff; while the heptafluoropropane fire extinguishing system is complex in design and high in cost; at the same time, both fire extinguishing systems require an independent storage room for bottle skids, which further expands the platform specifications and increases platform construction.
