To meet the requirements of Federal Law № 123-FZ dated July 22, 2008 «Technical Regulations on fire safety requirements», it is required to determine the estimated time of people evacuation and rescue from the hazardous production facility. To solve this problem, an experimental study of the processes of people evacuation and rescue from the structure of the real gas processing plant was conducted. Evacuation and rescue were carried out from the sections of the pipe rack most remote from the exits from it. The ways for the evacuation and rescue included both horizontal parts and stairs. Rescue was carried out using special stretchers, in which there was a dummy imitating an injured person. The time of evacuation and rescue was determined when moving both down and up, which can take place at the enterprises of the oil and gas industry. The time of movement in different sections was determined by the stopwatches. Based on the measured time and the parameters of the sections along which the movement took place, the movement speeds during evacuation and rescue were found. The evacuation experiments involved untrained people, while the rescue experiments involved professional rescuers. The average movement speeds in the evacuation simulation were as follows: down the stair — 100 m/min, up — 44 m/min, along the horizontal section — 193 m/min. The average movement speeds with a victim during the simulation of rescue were the following: down the stair —22 m/min, up —16 m/min, along the horizontal path — 102 m/min.

Abstract In general, the lifetime of the offshore oil and gas platform is about 20–30 years, and a large number of oil and gas platforms is approaching the end of their service. So, how to decommission these oil and gas platforms safely and cleanly becomes an urgent problem for the oil and gas industry and related organizations. And the costs for decommissioning equipment and services are expected to be as low as possible. It is important to develop the innovative removal techniques to reduce the overall cost of decommissioning. In this paper, we propose a new concept to remove large and heavy structures with a single lift, utilizing three semi-submerged vessels. The main process of the twin-lift solution for decommissioning includes two semi-submerged vessels lifting the topside together, and then carrying the topside to the third semi-submerged vessel. This method is simple in principle and does not require the manufacture of new special vessels, only needs to make simple modifications to existing semi-submerged vessels. It requires high positioning accuracy especially under environmental disturbances to ensure the safety of transportation. To ensure efficiency and safety, we develop a dynamic positioning (DP) system and perform a wave tank test for such a twin-lift decommissioning solution. Some aspects of an experimental facility set-up for scaled model test with dynamic positioning system are described. It includes the topology of the experiment and details of the deck mating, DP and monitoring system.

Push for sustainability is evident in areas such as energy generation where the focus has been on finding new deposits to outpace drawdown on existing reserves. Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight exploration and adoption of optimizing FGR that may be beneficial if flare gas can be recovered, instead of burning. The output of the study may have a significant impact for refineries towards both economic and sustainability towards greening. In a nutshell, this study highlights the efficacy of reducing ‘flare gas system’ towards environment-friendly ‘greening’ aspect as the core of designing.

Progress of the global energy industry as well as resources of natural gas of Russia were indicated in this article. The main region of their development over the years is Western Siberia, where more than 80% of gas reserves are explored. It is from here that the main stream of Russian gas flows to countries in Eastern and Western Europe. To date, good prospects have been opened for the preparation of gas reserves and production in eastern Russia with the launch of the Power of Siberia gas pipeline, which determined the high importance of this region, which is of strategic interest to the gas industry in Russia. The main resources of natural gas will be located in remote from the existing gas transmission system, inaccessible areas and areas with a harsh climate, where there are no large markets for the consumption of hydrocarbons. In connection with this, the search is underway for the transportation of natural gas, alternative to pipeline transportation, to the places of consumption. Three possible options are considered. According to the “General scheme for the development of the gas industry for the period up to 2030” , one of the promising options for the development of gas processing industries is the development and implementation of efficient technologies for the production of synthetic liquid fuels (GTL technology) aimed at solving the problems of developing small, mature and hard-to-reach natural gas fields. The special emphasize was made on one of the promising variants of gas-processing productions development - development and implementation of GTL (Gas to liquid) technology as a new method of production of synthetic liquid hydrocarbons from natural gas. Relevance, possible advantages, and prospects of GTL technology were also mentioned. The example of the Republic of Sakha (Yakutia) shown the possibility of using GTL technology, using as a raw material of natural gas of the Middle-Vilyusk gas condensate (gk) field. Also shown in this article are experimental details of the study of an individual hydrocarbon gas composition, which was determined using the gas chromatography method. The conclusion was made on the Republic's Oil and Gas Complex's overall potential cost-benefit in case of GTL technology implementation.

AbstractThe present manuscript reviews state-of-the art models of hydrogen-assisted cracking (HAC) with potential for application to remaining life prediction of oil and gas components susceptible to various forms of hydrogen embrittlement (HE), namely, hydrogen-induced cracking (HIC), sulfide stress cracking (SSC), and HE-controlled stress corrosion cracking (SCC). Existing continuum models are compared in terms of their ability to predict the threshold stress intensity factor and crack growth rate accounting for the complex couplings between hydrogen transport and accumulation at the fracture process zone, local embrittlement, and subsequent fracture. Emerging multiscale approaches are also discussed, and studies relative to HE in metals and especially steels are presented. Finally, the challenges that hinder the application of existing models to component integrity assessment and remaining life prediction are discussed with respect to identification of model parameters and limitations of the fracture similitude, which paves the way to new directions for further research.

The transition to an innovative way of development in the gas industry is associated with deep, comprehensive processing of natural gas, the start-up of manufacturing products with high added value. In terms of proven reserves of natural gas, Russia ranks number one in the world, the demand is constantly growing both at the domestic market and for exports. Natural and associated petroleum gases of many oil and gas condensate fields in Russia are multicomponent systems that contain a number of components important for the gas chemical industry (ethane, propane, butane, etc.). The most valuable of these is helium. The purpose of this work is to study the problems and prospects for the development of the helium industry in Russia and in the world. Using the methods of economic analysis, generalization and synthesis, the authors estimated the volume of reserves of helium-saturated gases in the fields of the country and Eastern Siberia, the state of helium production, the potential for using helium in the sectors of the Russian economy, the possibility and conditions of competitive entry into the world market. As a result, they detected Russia’s technological inferiority in a number of industries, coming from the low demand for helium, the location of potential consumers far from production centers, the high cost of helium production, the lack of reliable methods of its transportation, etc. At the same time, full-scale helium demand satisfaction of Russian industries is associated with the construction of the Amur Gas Processing Plant. The demand for helium in the countries of the world is constantly growing, an increase in consumption is observed in traditional industries and in the field of innovative technologies. The US dominance in the production of helium is gradually declining due to the depletion of some deposits. The authors make a conclusion that after 2030 Russia can satisfy domestic consumption of helium to bring the industry to an effective economic and environmental level and, while reducing the cost of production, become a major participant in its world market.
