Abstract
As a modern infrastructure for offshore oil and gas resources development, offshore platforms have many advantages, such as high efficiency, concentration, flexibility, and repeatability. At the same time, its upper module environment is bad, the equipment is numerous, has the very big risk. In case of fire and explosion and other accidents, it is difficult to get timely rescue. Therefore, fire risk assessment for offshore platform is very necessary. This paper focuses on the research results in the field of fire risk assessment of offshore platforms at home and abroad, points out the shortcomings of current research, and provides reference for risk reduction and effective prevention of offshore platform operations.
Highlights
Fires on offshore platforms mainly include the following types: Spray fire: the medium processed on the platform is mainly crude oil or natural gas, which is extremely combustible
The main steps of fire risk assessment for offshore platforms can be summarized as follows: (1) Clarify the system and related problems according to the design scheme of the offshore platform, the engineering stage it is in, the structural composition, and the requirements for the confidence of the analysis results;
The probabilistic risk assessment method is based on a large number of experimental data and accident statistical analysis, so the reliability of the evaluation results is high
Summary
Fires on offshore platforms mainly include the following types: Spray fire: the medium processed on the platform is mainly crude oil or natural gas, which is extremely combustible. Once it encounters the ignition source after leakage, it will be ignited and cause a fire, just like the flame ejector, forming a spray fire.[2]. Steam cloud explosion: An explosion caused by corrosion failure of a natural gas pipeline or delayed ignition caused by material leakage during mechanical failure It mainly relies on the blast wave to cause damage to people and buildings.[3]. Because crude oil and natural gas leakage will cause serious Marine environmental pollution, the risk assessment of relevant facilities of offshore platforms is of great significance
