Problems solved by technology
The problems we are facing are as follows: in the construction and production process of marine engineering, monitoring systems are currently being developed more, but there is no in-depth research on risk early warning and control methods, that is to say, only the monitoring function is realized, but not effective. control, and there is no unified security risk management system
In the event of major accidents such as leakage, orderly and effective risk warnings cannot be implemented, resulting in chain events such as fire explosions, structural and equipment damage, and casualties, which have seriously affected national property and people's lives.

Embodiment Construction
[0042] In the following, the leakage situation is first described, that is, the leakage model is established. There are many reasons for the leakage, mainly including equipment, personnel, management system and external environment and other factors. Once a leak occurs, the flammable gas will mix with the air after leaking, and the leaked liquid will also form a liquid pool, which will evaporate in the air to form a gas, which will then spread. If the combustion limit is reached, combustion or explosion will occur when encountering an ignition source, endangering the safety of the entire production device. The diffusion of toxic gas covers a large space and affects a wide range. If the series of reactions triggered by the leakage are not effectively warned and controlled, it will eventually cause catastrophic losses of personnel and assets.
[0043] From the occurrence of the initial incident to the final accident, it involves various processes and procedures, and it is a dy...

The invention belongs to the field of safety of offshore oil production, and relates to a leakage risk early warning method for an offshore oil and gas production device. In the method, five stages, namely initial leakage early warning, ignition early warning, result upgrading early warning, personal injury early warning and capital loss early warning, are set in turn according to process featureand process analysis of offshore oil and gas production; and when a leakage phenomenon is found, risk early warning is performed stage by stage according to the five steps. By the method, stage earlywarning and control of a leakage risk can be realized, the danger of the entire production process is reduced to the minimum level, and the requirements of safety, ordered operation and management ofthe offshore oil and gas production are met.
Description
technical field [0001] The invention belongs to the field of offshore oil production safety, and relates to an early warning method for leakage risk of an offshore oil and gas production device. Background technique [0002] At present, there are still many problems in the risk control and management of the construction of offshore oil and gas processing facilities, especially the risk control technology in the field of deep-sea oil development engineering has not yet reached the informationization, systematization and scientificization. The problems we are facing are as follows: in the construction and production process of marine engineering, monitoring systems are currently being developed more, but there is no in-depth research on risk early warning and control methods, that is to say, only the monitoring function is realized, but not effective. There is no unified security risk management system. In the event of major accidents such as leakage, orderly and effective ri...
