Object and purpose of research. This paper discusses offshore oil & gas platforms as complex social and technical systems. The purpose is to consider the results of the research on development of recommendations aimed at improving the methodological apparatus for making management decisions to insure the offshore oil & gas field structures safety operations. Materials and methods. This work followed common methods of theoretical studies and was based on KSRC guidelines, risk management standards, as well as relevant publications, both Russian and foreign. Main results. Existing methodological recommendations on safety decision-making for offshore oil and gas facilities were systematized. The task of describing the implementation of decision-making methodology intended to ensure safe operation of offshore facilities and their equipment has been successfully accomplished. Conclusion. Methodological recommendations on decision making suggested in this paper with reference to the operation of offshore oil and gas facilities are intended to improve their safety, as well as to prevent or mitigate their possible accidents (failures) and justify the choice of optimal cost-effective solutions.

Fixed platform have been widely employed in the offshore oil and gas reservoirs development. Pile foundation reliability is critical for these platforms where drilling, production and other functions are integrated. The lifting operation for the long pile, being a key step in the jacket installation, has been considered for further developments. With deep water developments, the sizes and weights of long piles are reasonably bigger. The corresponding process and equipment employed are subsequently altered, which brings challenges to developing a cost-effective, easy-operable approach for lifting operation. In this paper, the technology for the offshore long pile upending lifting operation including pile feature, installation methodology, lifting rigging and analysis model, covering water depths ranging from shallow to near deep water zone (60–300 m water depth) has been suggested. In addition, the applicability of the adoptable novel approaches has been discussed considering the practical project experience.

Production units located in the Brazilian marine environment are responsible for the production of 95.7% of oil and 78.8% of natural gas of Brazil causing economic, environmental, and social impacts motivating us to construct a system of indicators as a tool aimed to improve the sustainable management practice of these production units. To date, one of the tools most used by the oil industry is the sustainability report, oriented by guidelines from international organizations. However, these reports have a corporate character being unable to help the sustainability management of production units’ activities. The indicators were selected based on a systemic approach, using current knowledge on sustainability indicators, together with the survey of aspects relevant to the operation and management of offshore oil and gas production units. This paper describes the proposed indicators and presents the hierarchical structure of the system, built on the economic, environmental, social, and operational dimensions. The application of the proposed system of indicators, based on multicriterial and multiple decision-making analyses, validates a complex decision process, providing improved sustainable management of offshore production units by identifying points for which the necessary measures and actions can be implemented. Keywords: offshore oil and gas production; sustainability indicators; multicriteria and multiple decision-making analyses.

Steel risers for deepwater offshore oil and gas field developments are subject to seawater on the external surfaces, produced fluids on the internal surfaces and to fatigue loading. This paper reviews current knowledge of the corrosion fatigue behaviour of welded stainless steel for risers and presents results of testing of supermartensitic, duplex and superduplex grades in relevant environments.
