Safety instrument system of semi-submersible platform

Abstract

The invention discloses a safety instrument system of a semi-submersible platform. The system comprises a central control system, an environment monitoring system, a pressure protection system and an underwater control system; the environment monitoring system, the pressure protection system and the underwater control system are connected with the central control system; the environment monitoring system is used for monitoring the marine environment and the motion state of the platform, the pressure protection system is used for monitoring and controlling equipment pressure, and the underwater control system is used for controlling an underwater valve. According to the system of the invention, the whole system forms an organic and unified monitoring whole body, the functions of all the systems are played to the greatest extent, resource sharing is realized, technical support is provided in the installation, in-place and acting production processes of the semi-submersible platform, smooth implementation and use of all facilities in the offshore installation period are guaranteed, after the platform is put into production, the facility safety and stable operation of each system in the marine environment, platform movement, pressure monitoring and underwater control are ensured.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering, in particular to a safety instrument system for a semi-submersible platform. Background technique [0002] The marine environment is complex and harsh, such as wind, waves, currents, sea ice and tides, etc. will affect the structure of offshore oil platforms. In addition, risks such as fire and explosion, falling objects, etc. will also directly affect the safety of offshore oil platforms, while environmental corrosion, Unfavorable factors such as marine organism adhesion, material aging and fatigue damage will also lead to the decline of the overall resistance of the offshore oil platform and affect its safety. [0003] Due to the water depth of today's semi-submersible platforms, their installation, installation process and underwater production monitoring will directly affect the safety of platform installation and subsequent production. Contents of the invention [0004] T...
