ABSTRACT This study investigates how seemingly similar external pressures elicited diverse sustainability reporting control systems and processes in a sample of Canadian companies in the oil and gas industry. Using interviews with companies and their stakeholders, we found that the type of sustainability reporting control systems depended on the managerial motivations and attitudes within companies as they responded to external pressures. More specifically, our results provide insight into how formal and informal sustainability reporting control systems were developed according to various managerial motivations and different types of stakeholder relationships. The type and balance between formal and informal control systems, in turn, influenced the sustainability reporting characteristics that the company was able to develop. We contribute to the literature by differentiating companies based on their institutional logics to deal with external pressures, managerial motivations, and stakeholder relationships, that in turn influenced their control system characteristics including reporting structures, information systems, and assurances.

The article discusses the design features of fuzzy controllers as part of automatic control systems for semiconductor compensators. Tendencies to the use of fuzzy logic and neural networks to solve problems with a large number of variables that are random are analyzed. The functional scheme of the automatic control system on the basis of fuzzy logic is considered. Some features of the fuzzy regulator are given. Questions of optimization of parameters of digital fuzzy controllers are investigated. The importance of the choice of the method of parametric adjustment of the fuzzy controller is shown. The options for choosing the quality criterion for fuzzy controllers are considered. The market of commercial software products for working with fuzzy logic is analyzed.

The oil and gas industry is moving steadily towards automation and remote control of processes, which has the added advantage of removing personnel from the immediate danger of the offshore workplace. However, significant challenges remain to be met before the more complex type of offshore facility (especially floating facilities) can be operated fully unmanned, particularly when it comes to maintenance and repair campaigns. In particular, even though human life may be protected, the consequence of a major pollution incident occurring as a result of lack of sufficient manned surveillance is increasingly unacceptable in today’s society, and solutions have to protect these requirements as well. With today’s technologies and the pace of innovation, it is not difficult to envisage facilities in the near future where manned intervention is reduced to a far lower level than currently prevalent, perhaps even eliminated as robotics steadily advance. We can already begin to consider design features and systems that will make new facilities ready for such advances so that projects can absorb benefits from innovation as it occurs. The role of independent bodies such as the classification societies is to assess the design, construction and operation of offshore facilities and issue certification that gives regulators, financiers and insurers alike the confidence to support developments. For floating facilities this includes formal classification and a requirement for detailed knowledge of the state of the structure. This paper explores the methods that the classification society can use to support the aims of the offshore industry for reduced manning with improved safety and reliability.

The author describes four main work directions of creating geophysical maps using modern software, represented by specialized systems (SSS) and geographic information ones (GIS). The technological features of data processing practice stages and creating geophysical fields’ digital models, the compilation and designing geophysical maps’ thematic content as results of geological and geophysical works are considered. The main tasks of combined use of GIS and SSS tools were identified. To overcome these shortcomings, additional tools were developed for ArcGIS, as the leading system in the oil and gas industry. They ensure the preservation of design parameters for color scales adopted in the SSS; automatic calculation of the labels’ rotation angle to the objects of point localization; maintaining the layer structure of map projects at exporting to publishing program formats. The solutions considered in the article can be applied for compilation and design of isoline maps in some other areas of thematic cartography, and can also contribute to improving the cartographic component of domestic geological and geophysical software products and geographic information systems.

Rocking machines of oil (RMO) are the main elements in the Russian oil industry in the field of low-yield wells. And increasing the energy efficiency of these machines is one of the most promising tasks in the interests of the oil and gas industry in Russia.The use of intelligent energy-saving stations for controlling the machine-shaker of oil on the basis of synchronous engines makes it possible to optimize oil production, by increasing the volume of production and saving energy resources. The main disadvantage of these stations is high cost, which is a deterrent for widespread use.One of the solutions to this problem is the use of a method that does not use the rotor position sensor, the so-called "sensorless method". However, all works related to the use of the "sensorless method" refer to the control systems of asynchronous motors.In this paper, the advantages of the control systems of a rocking machine on the basis of synchronous motors in front of asynchronous motors will be presented, the variants of motor control and the execution of the "sensorless method" are considered. Mathematical models of all elements of the control station are presented: rocking machine, synchronous motor, vector control system.
