A study of world experience in other industries, such as aviation, military and nuclear industry, has shown that non-trivial engineering tasks of creating complex systems require working at the intersection of several technical disciplines. In 1957, G. Goode and R. Macol emphasized the achievements of mathematical science in the system method of designing technical equipment. In their view, the main problem for design engineers is the ever-increasing complexity of systems that cannot be implemented by scaling small system implementation tools. The authors proposed to train specialists with a wide range of disciplines, as well as to form design teams for the implementation of complex projects. The development of system engineering in Russia began in the 1960s under the name of system engineering, the emergence of which was caused by the problems of building complex military systems. A new stage of the development of domestic system engineering came at the beginning of 2010. Problems arising from complex projects have led to a call for systemic engineering practices. This article focuses on describing the role of the integrator in the project and the requirements for its competencies based on international experience. The formation of a philosophy of system thinking and the introduction of system engineering in the oil and gas industry will improve the efficiency of asset management throughout the life cycle. Creating a new paradigm of thinking and approach to engineering activities inevitably leads to the training of new format specialists who will perform an integrating function that will allow to control safety, technology and project efficiency.
