Currently, oil-producing enterprises use a large number of different equipment (machines, drilling rigs, pumps, compressors, mobile power plants, cars, tractors, mining machines and complexes, etc.). Their operating conditions are complicated by the fact that they are far from the bases of expeditions and central mechanical work-shops, they experience significant alternating loads at high humidity and the presence of an aggressive environment. Because of this, they quickly wear out and fail. At the same time, physical wear and tear of the equipment threatens the normal functioning of the entire interconnected process of oil production, treatment and pumping, and can lead to local emergencies. Reliable operation of equipment is possible only when performing a maintenance and repair system that provides for a set of measures to eliminate progressive wear, reduce the number of failures, increase durability and level of use, and ensure the required performance and safety. Lean manufacturing involves fundamentally new approaches to the organization of production and offers a set of tools and techniques that can significantly reduce losses, reduce the cost and speed up processes.
