The research and development activities following the Piper Alpha disaster have resulted in significantly improved technical safety of oil & gas facilities offshore and onshore. This improved technical safety resulted from the development of goal-setting, risk-based approach, the objective of which was to open the routes for design optimization and remove previous constraints that addressed the worst case and was prescriptive. Despite this initiative, a Quantitative Risk Assessment (QRA), while still being carried out, often remains “disconnected” from the practical design and prescriptive methods still take precedence. Resorting solely to a prescriptive approach can result in adequate protection missing in places where it should be, and applied in areas where there is a low likelihood of the hazard. This Paper addresses the application in the facility design, risk based methods and known behavior of structures and equipment in accidents. It stresses the importance of practical experience in the application of fire and explosion protection, and adequate design and operational experience. The Paper focuses on fire and explosion hazards and is based on more than 30 years of the authors’ experience in supporting facility design and assessment. Such approach has resulted in solutions with improved technical safety and significant cost-savings. It addresses both new installations and modifications of existing facilities.

Fire And Explosion

Introduction. According to statistics, Russia is the third largest oil producer in the world. The processing, transportation and storage of such a large volume of petroleum products requires maintaining the constant operability of tank farms. However, a significant number of accidents and fires are occurring at these facilities, which significantly undermines production and economic stability. Goals and objectives. The need to keep reservoir parks in working condition poses a problem of increasing the level of fire and explosion safety of fire repairs. This type of work is often impossible without the use of equipment that can serve as an open source of ignition, which can cause an explosion. Methods. To justify the need to achieve a fire and explosion-proof state of working conditions when preparing the tank for repair, methods of analysis and classification of data on fires that occurred at oil production and refining facilities not only in Russia, but also abroad were applied. Results and discussion thereof. The article calls attention to the process of pre-repair preparation as one of the main causes of accidents at oil-related facilities. More than 34,7 % of the explosions are related to fire repairs. There is a need to improve the regulatory framework relating to the preparation of tanks for repair, as well as the use of modern mechanized mobile treatment plants and the use of highly skilled personnel for the organization of work. Conclusions. The development of various industries, agriculture, and electric heating systems encourages increased demand for oil refining products for the successful implementation of their activities. This demand increases both the number of oil production, transportation and refining facilities and the number of jobs and personnel to service those facilities. Therefore, fire safety of oil and gas industry facilities is a current problem. Key words: reservoir park, fire, oil product, pre-repair, cleaning, gas-freeing, firing.

The role coal in power industry is predicted to be increased in future that is caused by its large stocks and depletion of oil and gas fields. Due to production growth, deterioration in mining and geological conditions and broad mechanization of production, the quality characteristics of coals as ash content, particle-size distribution, humidity and sulfur content worsen. Therefore, practically all mined coal requires enriching. The smallgrade and fine concentrates received after enrichment often happen to be unsuitable because of their fineness for further processing or direct use. Therefore briquetting is applied for possibility of further processing or increased utilization efficiency. Compared to the conventional fuel the briquetted fuel possesses higher calorific capacity and bigger stability during storage and transportation.

Explosion Risk

The potential risk of an offshore processing facility is the major important part in the oil and gas industry due to its limited space causing difficulties in evacuation. An offshore processing facility is normally exposed to flammable oil and gas in the operating phase. Especially, uncontrolled hydrocarbon leaks or ruptures of the equipment present main threats. These failures can lead to fire and explosion disaster. Some studies have proposed fire and explosion assessment methodologies and made fire and explosion assessment tools. These tools can provide risk assessments result using physical effect modelling software and following the related standards or engineering practices according to accident scenarios. Nevertheless, existing fire and explosion assessment procedures are still not comprehensive enough to applicate a specific process due to its complexity and are not clear which stage in a project is appropriate for applying it. This paper focuses only on explosion accidents and discusses the development of an explosion risk analysis procedure possible to apply at process flow diagram (PFD) level. The explosion risk analysis procedure using PFD has 6 steps; modelling of a process, scenario selection, inventory calculation, frequency calculation, consequence modelling and risk estimation. It starts at modelling of a specific process using process simulation software, HYSYS. The process modelling can be optimized by the existing methods and finally provide the PFD for the specific process. In the scenario selection step, the information required to perform a risk analysis is identified. The inventory calculation conducts to calculate the inventory of a defined segment after sizing of the equipment in the PFD. The frequency calculation consists of leak frequency and ignition probability. The leak frequency can be calculated with historical database and the ignition probability can be calculated with a specific ignition probability model. The consequence modelling is conducted by using physical effect modelling software, PHAST. It can provide the distance to specified overpressure. Finally, at the risk estimation step, the risk results are evaluated. This procedure can help to applicate a specific process easily and provide explosion risk assessment tool at PFD level. This paper conducts the case study for a liquefied natural gas floating production storage offloading (LNG-FPSO) which is one of the representative offshore processing facilities. Especially, a natural liquefaction process in a LNG-FPSO, which liquefies the processed natural gas to store in a storage tank of a LNG-FPSO, is the most important process in terms of cost and risk. In the situation the most of ongoing or prospective projects for LNG-FPSO adopt dual mixed refrigerants (DMR) liquefaction process, the representative configurations of the DMR liquefaction processes are evaluated and compared. It can help decision making through providing which configuration has an advantage in terms of explosion accidents.

With the development of reserves of oil and gas condensate fields, there is a need to study oil and gas condensate in order to assess the possibility of pumping them in the form of a combined mixture. To this end, laboratory studies and bench tests of oil and oil-gas condensate mixtures with different content of gas condensate in the composition have been carried out. Basing on the results of laboratory study, It is established that the increase gas condensate content in oil leads to changes in its physical properties and fire and explosion hazard indices. It is shown that the optimal gas condensate content is up to 10 wt. %. The results of the study of asphaltene aggregates stability has not reveal the incompatibility phenomenon when mixing oil and gas condensate. It`s been determined by bench tests that the addition of gas condensate to oil leads to reduce the hydraulic losses of flow specific energy and the rate of growth asphaltene-resin-paraffin deposits. Thus, the mixing of oil with a content gas condensate is practically useful in the operation of the main pipeline.
