“…The peculiarities of the method have been studied and its efficiency has been tested using a conditional example. In the future, the authors intend to improve the economic and mathematical tools of the method proposed in the study, and to test it on the basis of integrated industries [15]. And the authors expect to present the calculation of the cost of production of the enterprises of the agro-industrial complex in Russia in subsequent publications.…”

This study solves the most important economic problem of developing a method for calculating the cost of each type of product in complex and multi-product industries. The performed analysis of the current legislation and the methods used for calculating the cost has led to the conclusion that today the solution to this problem has no scientific justification. The authors carried out a systematic development of procedures that allow building a scientific idea using objective information. It is implemented in the study by means of appropriate techniques and the construction of an economic and mathematical model that allows the development of an instrumental apparatus for the implementation of the method. With its application, the problem of calculating the production cost of seven types of final products for a conditional technological scheme of integrated production was solved. The results are also compared with the cost calculation obtained by other methods. In addition, a graphical and matrix analysis of the calculation results was carried out. The obtained results of calculating the cost of the final product make it possible to evaluate this method as workable, and the algorithm for its construction - as using the entire array of initial objective information.

“…The objective has been to prepare common teaching material in English and Russian in order to align the teaching and to serve as common ground for common research activities. Joint scientific publications have also been prepared, in particular related to the development of offshore oil and gas fields in the northern region (Bulakh, Gudmestad, & Zolotukhin, 2011;Efimov, Kornishin, & Gudmestad, 2013;Pribytkov, Zolotukhin, & Gudmestad, 2014). We suggest that these textbooks and publications will be useful and serve as basic reading when common Russian and Norwegian development projects take place in the future.…”

The Arctic region contains large amounts of natural resources considered necessary to sustain global economic growth, so it is unsurprising that it is increasingly susceptible to political, economic, environmental and even military conflicts. This book looks in detail at the preconditions and outlook for international cooperation on the development of Arctic petroleum resources, focusing on Norwegian-Russian cooperation in the Barents Sea towards 2025.The authors provide a cross-disciplinary approach including geopolitical, institutional, technological, corporate and environmental perspectives to analyze the underlying factors that shape the future development of the region. Three future scenarios are developed, exploring various levels of cooperation and development influenced by and resulting from potential political, commercial and environmental circumstances. Through these scenarios, the book improves understanding of the challenges and opportunities for Arctic petroleum resource development and promotes further consideration of the possible outcomes of future cooperation.The book should be of interest to students, scholars and policy-makers working in the areas of Arctic studies, oil and gas studies, energy security, global environmental governance, environmental politics and environmental technology.

Optimization of insulation on subsea oil and gas equipment can lead to significant cost and weight reduction. A judicious combination of commercially available Finite Element Analysis (FEA) software with evolutionary optimization algorithms can efficiently serve this purpose. In the present study, the optimization of insulation on a gate valve has been presented with due emphasis on the methodology adapted. A parameterized model of the gate valve with several dimensions of interest has been chosen for the numerical experiment. Of the various Design of Experiment (DOE) techniques, the Optimal Space Filling (OSF) method has been considered for generating the samples owing to its robustness and the associated computational cost. The insulation in subsea systems is usually supposed to satisfy two contradicting constraints, it must be ensured that the temperature of the production fluid remains above the Hydrate Formation Temperature (HFT) and at the same time the production fluid temperature cannot be too high, as to create structural damage of the seals in High Pressure High Temperature (HPHT) applications. The sample cases are run simultaneously in a cluster and a response surface is created using genetic aggregation using the various samples those are generated by OSF. The resulting response surface is finally subjected to optimization using the calculus based/gradient based methods. In the present investigation, the optimization is performed using the NonLinear Programming with Quadratic Lagrangian (NLPQL) and Adaptive Single Objective (ASO) Methods. The results obtained show that almost two thirds of the insulation can be effectively removed without compromising on the thermal efficiency of the system. Similar savings have been witnessed in several other cases/subsea geometries that the authors are aware of. The presented case is truly representative of a wide class of subsea applications and the proposed methodology can be suitably adjusted to customer specific requirements to provide suitable results.
