Full textAbstract:
A ship’s combat readiness is significantly dependent on the technical worthiness of basic ship equipment and mechanisms. Technical worthiness is determined by operation rates and depends on the condition of equipment. While using military equipment, one may expect the wear and tear of systems resulting from physical ageing, operation or combat damage. The restoration of ship’s technical efficiency is completed after returning to the harbour or during operations at sea. The tasks of restoring technical efficiency are performed in harbours and in naval bases by ashore elements of the repair system. During operations at sea a crew is able, to a limited extent, to carry out basic technical maintenance. The restoration of the technical worthiness and efficiency of ship equipment depends on appropriate logistic support.

The paper deals with the statistical data processing algorithms in operation system of radio electronic equipment. The main purpose is analysis of data processing algorithm efficiency according to the analytical calculations and simulation results. During radio electronic equipment operation failures are possible. These failures affect on the equipment’s technical condition that can deteriorate. In case of condition-based maintenance, it is necessary to detect the time moment of deterioration beginning. Therefore, in this paper the deterioration detection algorithm was developed according to Neyman-Pearson criterion with a fixed sample size. The initial data are times between failures of radio electronic equipment, and these data can be identified by the exponential probability density function. The step-function model was chosen for failure rate change description. To estimate efficiency the operating characteristic was calculated. The simulation based on Monte-Carlo method confirmed the correctness of theoretical calculations.

Purpose. To develop the method for increasing the efficiency of the equipment’s maintenance and repair system, ensuring necessary level of operational reliability of the equipment, safety and reliability of the electric equipment with minimal expenses on operation. Relevance. Aging of the power equipment in railway power supply systems sharply raised a need for assessment of its states and degree of risk for operation outside rated service life. In critical conditions of technological processes and operational modes of the railways it is necessary to increase the equipment’s operational reliability. The scheduled maintenance and repair system whose main technical and economic criterion is the minimum of equipment’s downtimes on the basis of a rigid regulation of repair cycles, in the conditions of market regulations in the field of repair in many cases does not provide the optimal decisions due to insufficient financing. The solution of this problem is possible by improvement of the maintenance and repair system. Under these conditions the main direction for supporting the operational reliability of power electric equipment on TS is a development of the modern methods based on individual supervision over real changes of technical condition of power equipment. Scientific novelty. In this article the authors proposed an integrated approach, on the basis of which can be developed the effective maintenance and repair system for traction power supply systems. Proposed approach allowed to react quickly to changes of service conditions on traction substations, to control the technical condition of power electric equipment under the conditions of uncertainty, to establish interrelation between quality of service and operational reliability of the equipment, to choose a service strategy on traction substations. Practical importance. The validity of the developed method was confirmed by the results of calculations and practically by choosing the optimal maintenance's option for transformer TDTN-25000/150-70 U1 (ТДТН-25000/150-70 У1) on traction power supply substation.

Full textAbstract:
Wastewater treatment requires energy-intensive technology. The demand for industrial and residential wastewater treatment is increasing, and it has been widely accepted that low energy consumption and high operating efficiencies are essential to achieve high operating benefits in wastewater treatment plants (WWTPs). In this study, characteristic parameters of equipment operation were collected and subject to statistical analysis for trend observations in combination with expert knowledge to monitor equipment operating conditions. A methodology was developed to monitor and assess operating efficiencies of industrial equipment while not interfering with the existing operation. The proposed methodology was applied to monitor the pump efficiency in a WWTP. The results showed that the new methodology resulted in real-time acquisition of statistical operating data and enabled online detection of abnormal pump operation. The energy loss to low operating efficiencies of a malfunctioning pump was prevented, thereby allowing the pump to operate at high efficiency with an extended equipment life.

Abstract The research aims to characterise the optimisation of a technological process depending on the main time parameters for production. The optimisation does not require to correct technical parameters of a system, but rather the organisational and managerial factors of the technological process. The workload is taken as an evaluation criterion, which factors in the probability distribution of time characteristics of computer process operations. Time characteristics that represent the performance of an operation influence the workloads of an operator and equipment, determining the productivity of the technological process. Analytical models were developed for the operational control of a production line efficiency considering the probability–statistical parameters pertaining to the performance of operations and technological equipment peculiarities. The article presents research results, which characterise the dependence of a production line efficiency on the type of equipment, and the duration of preparatory and final operations considering their probability. Under an optimal workload of the operator, the duration of the complete program changes linearly, regardless of the time required for the performance of operations by a computer without the involvement of the operator, and depending on the type of equipment. A managerial decision can be optimal under the condition that the factor of technological process efficiency (K_TP) tends to max. The developed method of analytical determination can be used to calculate the workload of both an operator and technological equipment. The calculations of the duration of a production line operation resulted in the methodology for the consideration of probability characteristics pertaining to the time distribution of the period required to perform operations, which influences the unequal efficiency of the production line. The probabilistic character of time distribution related to intervals of performed operations serves as a parameter in the management of technological process optimisation, which can be achieved using simulators of technological processes optimised in terms of their efficiency.

The results of implementing equipment qualification are analyzed. Such equipment is critical for the nuclear and technical safety of domestic nuclear power plants that are especially important for the implementation of the Program for extending the terms of out-of-project operation of power reactors that are capable of being used as powerful sources of electricity. Based on the comparison of published reliability indicators of domestic nuclear power plants before and after implementing the qualification, it is shown that still there are problems to be solved. The perspective of further enhancing the reliability of the operation of domestic nuclear energetics is considered, by implementing radiation functional testing methods that are been developed at the INR NAS of Ukraine for a long period. The basis of this method is detailed research and operational control of all processes that occur in critical equipment in any operating modes of nuclear reactors to form a resource history of the equipment and to provide operational information about the remaining resource and the expected time of its failure to an on-line object operator.

Full textAbstract:
The rail–water coordinated operation area in a container terminal is the key place to operate the transshipment of intermodal containers between the rail and the sea—the handling efficiency in which can affect the overall transport turnover efficiency. A complicated operational process for various handling equipment exists in this coordinated operation area and can lead to a large amount of energy consumption and environmental pollution. This study proposes an integrated optimization approach to manage the multiple equipment integrated scheduling and storage space allocation problem in an energy-efficient way. A bi-objective optimization model is proposed to minimize the overall operation time and energy consumption, in which the handling operations of imported and exported intermodal containers are considered simultaneously. A genetic algorithm based heuristic algorithm is developed to solve the problem. Results from computational experiments indicate the feasibility and effectiveness of the proposed model and algorithm, verifying that a near-optimum solution can be obtained for large-scale problems efficiently, which contributes to the improvement of operation services in rail–water intermodal container terminals.

The object of researches is brake systems of innovation freight cars. The work purpose consists in the assessment of braking system effectiveness in innovation freight cars and in standard ones at different operation modes. 
 The scientific novelty consists in the definition of the dependence of a slide block depth on the length of wheel pair skidding motion and braking distance dependence upon car speed. During the work there was carried out a retrospective analysis of cases with traffic safety violation connected with the formation of excessive sliders in freight cars in organized trains because of the violation of braking equipment normal operation. By means of the least-squares method there was obtained a linear equation defining the dependence of slider depth upon the skidding length of a wheel pair. As a result of the work there were defined parameters of defect formation on freight car wheels at their skidding, the calculations of braking system efficiency in different freight cars were carried out. 
 In the course of the analysis of freight car braking efficiency there are obtained equations of braking length in the accepted range of speeds at the beginning of braking for empty and loaded states. Minimum values of the design factor of braking block pressing in translation to a train length of 200 shafts in the empty state were 0.2256 for a speed of 40km/h, in the loaded one – 0.1781 for a speed of 120 km/h at the standard values 0.22 and 0.14 respectively. By means of calculations and experiments it is proved that composite braking block pressing force on a shaft exceeds 4tf/shaft, and that of cast-iron – 10tf. Accordingly, a car with the shaft load of 25 tf/shaft and accepted parameters of a braking system may be operated up to the speeds of 120 km/h inclusive without limitations.

In recent years, energy conservation has become a major focus in the industrial sector. Many office buildings in Japan achieve energy savings by introducing highly efficient equipment and systems, such as high-temperature cooling water (14 °C), which increases heat source efficiency. However, such equipment requires adjustments to increase operational efficiency. In this case study, the efficiency of equipment using high-temperature cooling water was further improved through operation control optimization. The energy efficiency before and after the improvement was compared. The target building has chilled and hot water supplied to each floor from district heating and high-temperature chilled water supplied from cooling chillers on the rooftop. The energy consumption of two floors was evaluated: a subjective floor with equipment using high-temperature cooling water installed, and a common floor with a conventional system. After on-site verification, changes were made to the operation control of the cooling towers, condenser pumps, primary pumps, secondary pumps, and air handling units. As a result, the coefficient of performance of the water-cooled chiller and the whole system improved by 0.40 and 0.45, respectively. The flow rate of the air conditioning equipment using high-temperature cooling water decreased while maintaining an equivalent amount of heat extraction. In conclusion, the efficiency of the equipment was further improved by operation control optimization.

During the operation of state district power station, it is necessary to calculate the technical and economic performance (TEP) of the equipment operation based on the results of measuring the parameters of heat carrier flows. In particular, such tasks are solved during thermal (balance, functional) tests of heat and power equipment, as well as during the preparation of monthly technical reports of the state district power station on thermal efficiency. Therefore, the urgent task is to develop the model of calculating the indicators of the thermal efficiency of the equipment of the state district power station using modern computerized tools. Methods of business processes modelling, and mathematical modeling are used to solve this problem. The developed model of the project is based on the principles and approaches of systems analysis. The model is adapted to a specific subject area and allows you to optimize the process of calculating the key parameters of the efficiency of the state district power station operation: power plant capacity, heat load, specific fuel consumption and overall efficiency of the power plant. An information system model was developed to automate the process of calculating the TEP to ensure a more economic operation of equipment due to reducing the time and cost of this process.Based on the analysis of the developed models, a project was developed to automate the process of TEP calculating to ensure more economical equipment operation, to predict equipment repair, and assess the quality of operating personnel work. The paper presents the architecture of the solution of the information system for TEP accounting, the model of the subsystem of calculation modules, the structural diagram of the operation of the data collection module, the interface of designed information system.

Ground coupled heat pump has become an attractively alternative way to cool and heat buildings in China, however, in practice their operation and effect especially on the performance of heat exchanger are unsatisfied. In this paper, the influence of buried tube depth and operational mode on heat exchange performance were studied by experiment. The experimental results showed that intermittent operation mode will help to improve energy efficiency of buried tube,and improve the host operating efficiency. In the operation, buried tube will produce inevitably cold and heat accumulation effect in surronding rock mass, and result in water temperature of buried tube oulet rising (summer) or decreasing(winter), cooling temperature of the condenser (summer) increasing, evaporation temperature of evaporator decreasing (winter), then the operating efficiency of host machine in the actual operation would be decreased. It is suggested that ground source heat pump system with auxiliary cold/hot equipment should be considered in practice.

To reduce the moisture content of coal gas in combined cycle power plant, a new type dehydration equipment is introduced. The curved plate dehydration equipment is composed of many pieces of stainless plate which has some collection hooks at every corner. Meanwhile, a new method on measuring moisture in gas by using superfine fibreglass is introduced.The gas-water separation efficiency was calculated by the difference of moisture content before and after the curved plate dehydration equipment. The dehydration efficiency of curved plate in combined cycle power plant system was tested under different operating load, the results show that gas velocity and gas/liquid ratio have a great influence on the coal gas dehydration efficiency. If the washing water flow rate and pressure are changed, the efficiency will change at the same time. The moisture content is low when the spraying nozle works at a high water pressure. The operation water pressure and working voltage of electrostatic precipitator have been proposed by testing and analysis. It will have great advantage to the safe operation of turbine.

The operation of technical objects is subject to the regulatory conditions established by their manufacturer. Regime of regulatory conditions keeping needs to be controlled. A new technical object at the time of commissioning has an initial, maximum level of technological efficiency of operation, including ecological, economic and general technical components, and has an initial, complete working capacity resource too. During operation, the technical object wears-out, its technological efficiency is reduced. In accordance with the international standard and the standard of Ukraine, a technical object that has exhausted a resource is subject to decommissioning and replacement with a new technical object, since at a level of technological efficiency that is less than the minimum, the use of technical object is inexpedient. However, in the current difficult economic conditions in Ukraine, the replacement of worn-out equipment with a new one is impracticable. Further use of worn-out equipment is inevitable. To control a worn out object, complex automation is required. The technical object is studied in this direction from three positions. The first is to study the process of wearing-out. The second is the prediction of wearing-out dynamics. The third is the object control in the process of its wearing-out. The development of the theory and practice of worn out objects automating leads to the formulation of new tasks. With long-term operation of the equipment, it is necessary to periodically adjust its characteristics. It is necessary to create adaptive automatic control systems that take into account the degree of equipment wear-out and conditions of its operation. It is important to establish the patterns of influence of the current state of the equipment and the operating conditions on its residual resource. A productive way to increase the efficiency of worn-out equipment is its renovation by implementing measures that increase the level of efficiency of the most worn-out elements of technical objects. The technical objects control with registration their wear-out will ensure compliance with the regulations for their operation.

AbstractThe operation system determines the efficiency of the intended use of radio equipment. The operation system includes radio equipment, documentation, operational resources, personnel, processes, data processing algorithms, etc. The operation process is associated with conditions of priori uncertainty of models, parameters, external factors, etc. The main element for monitoring is technical condition of radio equipment. In a general case, this condition can deteriorate. The problems of technical condition deterioration analysis can be considered in terms of changepoint study. The present paper concentrates on the problem of synthesis and analysis of method for changepoint detection during radio equipment operation. The detection algorithm is constructed based on Neyman–Pearson criterion with sample size accumulation. During algorithm synthesis the thresholds were calculated according to Bellman’s approach. The problem of synthesis and analysis was solved by two methods: analytically and using statistical modelling. The efficiency measures for this algorithm are the probability of correct detection and mean time of decision making. The proposed algorithm has advantages in mean time of decision making compared with CUSUM detection method.

Modern radio-electronic systems (RES) of weapons and military equipment (WME) are more functionally and structurally sophisticated that results in high requirements for their effective operation organisation. Insufficient level of technical knowledge among RES WME operational and maintenance personnel often results in increase of operability restoration period of these items in case of failures. This, in its turn, results in decrease of the readiness level of the RES WME pieces. In order to reduce duration of the RES WME restoring repair in case of failures, methods and tools of the auto-mated informational support of the operational and maintenance personnel activities related to the WME operation and restoring repair are developed. This article is devoted to development of a model of the automated informational support of the personnel activities in order to find rational options of the RES WME maintenance and repair organisation.

This algorithm fully considers the actual demand of industrial application, automatically determines the number of clustering class, solves the problem of large cost and low efficiency of traditional clustering algorithm processing massive historical data, and ensures the efficiency of regression forecasting process.

A modern coal mining enterprise, whether it is a coal open-pit mine or an underground mine, is a high-tech operation with a large number of various employee's equipment, both for basic technological operations and for auxiliary operations. The efficiency of minerals extraction, in particular coal, depends on the reliable operation of this equipment. The extraction area is the main production site on which mining of coal depends at the mine, that is why this particular production site should be given special attention in terms of its safe and efficient operation. Therefore, a comparative analysis of the performance indicators of the coal mine extraction area is an urgent task. The present study gives the analysis of standard and actual performance indicators of the extraction site in the conditions of the mine "Polysayevskaya" of JSC "SUEK-Kuzbass" for a typical month of extraction. The analysis provides prerequisites for increasing the efficiency of coal mining, which will affect the cost of production and the net profit.

Model simulations for bioenergy harvest planning need to utilize equipment-capacity relationships for equipment operating under the high-yield conditions typical of a biomass crop. These performance assumptions have a direct bearing on the estimates of machine capacity, the number of machines required, and, therefore, the cost to fulfill the biorefinery plant demands for a given harvest window. Typically, two major issues in these models have been poorly understood: the available time required to complete the harvest operation (often called probability of workdays) and the capacity of the harvest equipment as impacted by yield. Simulations use annual yield estimates, which incorporate weather events, to demonstrate year-to-year effects. Some simulations also incorporate potential yield increases from genetically modified energy crops. There are limited field performance data for most current forage equipment used for harvesting high-yield biomass crops. Analysis shows that the impact of wrap/eject time for round balers resulted in a 50% reduction in achieved throughput capacity (Mg/h). After the maximum throughput is reached, the cost of the round bale operation (3.23 USD/Mg) is double that of the large-square baler (1.63 USD/Mg). The round baler achieved throughput capacity is 50% less (32.7 Mg/h compared to 71.0 Mg/h) than the large-square baler.

Abstract At various locations in Tokyo, the excess pressure of water entering the water supply distribution reservoirs is adjusted by pressure reducing valves, wasting unused energy. The installation of hydraulic power generation equipment is now promoted in place of the pressure reducing valves. This is a renewable energy source as the method produces no greenhouse gases and reduces fossil fuel use. The results of research into the operation of the hydraulic power generation equipment enable the water supply operating system to optimize the inflow rate for power generation without affecting the stability of the water supply. This has increased the amount of power generated and enabled earlier recovery of total costs.

Mine transport is an integral part of mining process. The performed analysis of modern monorail autonomous locomotives indicates that this type of underground auxiliary transport is the most promising today due to a number of advantages that were identified in this study. To assess performance indicators of mine monorail locomotives, a number of characteristics are currently used, for instance, the dependences between several parameters of propulsion system operation. The type of characteristic is determined by an independent variable to be selected from the list of the operational or design parameters. To substantiate performance indicators of autonomous mine suspended monorail locomotives, the authors proposed the relationship between the characteristics of the traction energy chain equipment and the diesel locomotive propulsion system efficiency factor. To assess the efficiency of mine suspended monorail locomotive operation, a composite indicator for assessing efficiency of various types of traction was proposed: the operational efficiency factor. This indicator takes into account varying the efficiency factor of the energy chain units depending on their operating modes. When determining the functional dependencies of varying the efficiency factor of power and auxiliary units of monorail locomotives, a grouping of the main parameters according to the features depending on the economic characteristics of the propulsion system and its operating modes was proposed. The operational efficiency factor of the locomotive as a whole is determined both by the economic characteristics of all units of its energy chain and by the modes of their operation.

Mean time to failure of modern machinery and equipment, their individual parts and components can be calculated over the years. Methods for determining the optimal frequency of maintenance and repair, based on the collection and processing of information about the reliability of industrial facilities, during their testing in laboratories and at special sites, as well as through long, operational tests require considerable time and become expensive. The purpose of this work is to develop methods for processing information about the reliability of equipment in automated systems for maintenance and repair, which will reduce the time to collect information on equipment failures and improve the cost-effectiveness of maintenance and repair. Small, multiple-censored right-side samples of equipment operating time for failure are formed as a result of failure data collection in an automated system for equipment maintenance and repair. Calculation of reliability indicators for such samples is performed using the maximum likelihood estimation method. The article presents experimental studies of the accuracy of the maximum likelihood estimates of the parameter of the exponential distribution law for small, multiple right-censored samples. The studies were carried out by computer modeling of censored samples, similar to samples that are formed when monitoring equipment during operation. Methods of simulation modeling of random processes on a computer and methods of regression analysis were used. Analysis show that most of the maximum likelihood estimates obtained from small, multiple-censored right-side samples have significant deviations from the true values. A technique for improving the accuracy of maximum likelihood estimates is proposed. The scientific novelty is regression models are constructed that establish the relationship between the deviation of the maximum likelihood estimate from the true value and the parameters characterizing the sample structure. These models calculate and introduce corrections to maximum likelihood estimates. The use of the developed regression models will reduce the time to collect information about the reliability of the equipment, while maintaining the reliability of the results.

Vertical Sieve-tray Tower (VST) and grinding system are the key equipment of cement production line. The production of VST and grinding system involves complex physical and chemical mechanisms, harsh operating environment, fuzzy changing boundary conditions. It shows a multi-field coupling integrated complex multiphase. Yield, quality, efficiency, safety, energy conservation, emission reduction and other operational indicators of the system is not only interrelated but also mutual restraint. The physical relationship between system operation and system control performance indicator is not clear, so it is difficult to adopt traditional control methods based on mechanism modeling and model-based analysis. In view of that, a design of process-optimization expert control system is proposed for VST and grinding system. The system model is designed according to energy consumption and operating experience. It has optimal control of the entire procession for equipment operation and achieves minimum energy consumption to meet the production requirements.

The fuel system largely determines the longevity of a diesel engine. This is due to the great influence of the fuel transfer process on its operating cycle. The operational characteristics, efficiency and ease of starting the engine are determined by the state of the engine power system, which is demanding for a diesel engine and requires careful regulation. The fuel injection process in a diesel engine largely depends on the design parameters of the fuel equipment. They change under the influence of external and internal factors. Reasonable standard terms and volumes of fuel equipment repairs are of great importance for the operation of diesel engines. These issues can be optimally solved only on the basis of statistical and experimental data on the nature and rate of growth, depending on the duration of operating conditions, superior types of wear on the working surfaces of the fuel system parts. The service life of fuel equipment is determined by the reliability and durability of precision pairs: plunger, pressure valves and injector nozzles. Operational defects of precision parts change by 12-17% such parameters of the injection process as cyclic feed, ignition timing, injection duration, maximum cycle pressure, can worsen the power and economic performance of a diesel engine. Therefore, the problem of improving the reliability and durability of precision pairs is relevant, the study of which is currently receiving much attention. Especially from precision pairs, pressure valves deserve attention. Their restoration after operation does not require expensive equipment and energy consumption, but the parameters of diesel engines depend to a large extent on their operation. Improving the injection characteristics of fuel equipment that has served its service life with a change in the parameters of the injection valve in the conditions of repair and maintenance workshops is quite affordable.

It becomes more and more obvious that focusing solely on economic efficiency is not a good strategy for business development. Moreover, a quantitative assessment of the integral operation indicators, including complex indicators of efficiency, environmental performance and safety, can help to protect a business against possible bankruptcy [1]. In the electric power industry, this is reflected in the modified concept of operational efficiency (OE). OE is not only the usual economic efficiency, but also operational reliability and safety. There is a good reason for such modification of the concept. In electric power systems (EPS), the actual service life of about 60% of the main equipment, devices and installations exceeds the rated value. We shall refer to such equipment as “overage facilities” (OF). The failure of such OF is the main cause of unacceptable system emergencies. During the rated service life of EPS, only a quantitative assessment of operational economic efficiency is performed. Operational reliability and safety (for example, the average monthly values) are not calculated, since they are guaranteed by the manufacturer. However, after the warranty period is over, operators still do not evaluate complex indicators of operational reliability and safety, since there is no methodology for their assessment. Moreover, it is necessary to be able to calculate the integral OE indicators which reflect the actual values of economic efficiency, operational reliability and safety. It can significantly reduce the risk of mistakes when choosing the methods for organizing operation, maintenance and repair. Then, decisions will be made based on comparing these integral indicators. The random nature of changes in technical and economic indicators (TEI) is determined by the random nature of changes in the integral OE indicators. The article presents new methods and algorithms for determining the feasibility of classifying the integral OE indicators of OF.

Advanced cleanliness requirements in production are forcing industrial companies to include new cleaning processes into their manufacturing process. Complex cleaning operation procedures can lower process productivity and at the same time are responsible for substantial parts of the overall energy consumption. An optimization of cleaning processes with respect to cleaning duration, energy consumption and efficiency can therefore contribute to cost reduction significantly. This article presents a procedure for real data based assessment of industrial cleaning equipment. Based upon the resulting information of the procedure, productivity ratios and energy consumptions can be determined up to individual cleaning components. This creates the required transparency to derive customized production and energy efficiency optimization measures.

Abstract The main task of the maintenance services in hard coal mines is to ensure continuous operation of the equipment (machines). The measurable effect of these actions should be the reduction of maintenance costs of equipment (machinery) and thus the reduction of production costs – coal mining. The paper presents an issue of failure rate of technical measures applied in the mining process. In order to ensure greater efficiency and productivity, it is necessary to find the causes of the most frequent failures in this process and effectively counteract them. As a result of these activities, the production availability of machines/equipment involved in the mining process will increase. This will to a large extent ensure failure-free and uninterrupted progress, increase productivity and improve the quality of manufactured products, as well as reduce the operating costs of equipment (machines), and thus reduce production and product costs. This effect should consist mainly in the control of rational, safe and effective use and operation of equipment (machines) in the exploitation process. An algorithm implemented in one of the hard coal mines was presented. The technical condition of underground mining equipment was observed by periodical measurements of vibration parameters at selected points on the machine – measurements were conducted with a vibration pen. The aim of this research is to improve the reliability of technological process of a mining plant through its failure-free operation. In order to achieve this objective, i.e. the efficiency of a mining company, it is necessary to reduce its costs. The action that leads to this aim is a proper assessment of the technical condition with regard to the equipment used in technological process.

In optimizing and managing the life cycles of submersible electrical equipment (SEE) for oil production, an integrated approach to the organization of maintenance and repairs (MRO) is advisable based on the development of a more advanced strategy for carrying out repair cycles. It is stated that the maintenance and repair strategies adopted by the oil industry do not fully ensure operational efficiency, which leads to an increase in premature equipment failures, a reduction in turnaround times and, as a result, losses for oil companies. The advantages and disadvantages of approaches to organizing the operation of SEE on the operating time and the actual state in the planning, implementation of maintenance and repair, as well as the feasibility of their complex application are evaluated. It is proposed to use statistical models to make an informed decision on determining the composition and period of MRO, forecasting the boundary states of sets in general and specific SEE electrical installations. At a given operating time, it is possible to determine the basic laws of the appearance of defects and the mean time between failures (MTBF) of the elements, as well as the fleet of equipment of oil-producing enterprises as a whole. The results obtained are the rationale for a set of recommendations to improve operational efficiency and optimize life cycle management of submersible electrical equipment for oil production.

Since the launching of Sea Toll Road Program in 2015, the improvement in ports’ operation systems has become Indonesia’s foremost necessity. This improvement commonly leads to equipment modernization, while realistically, modern equipment does not always amount to a productive performance, especially in the context of small-scale ports. Instead, it is prone to creating wasteful capital and maintenance cost as well as making the planning time ineffective. This study compares two options of port operation systems in a small port, which is conventional and technologically-advanced method for dry bulk cargo. It results in thin gaps between each option’s financial assessment variables, which are Internal Rate of Return, Benefit/Cost Ratio and Payback Period, regardless of a stark difference between each option’s equipment cost. This study concludes that with the right approach, the conventional operation system is still the most efficient option compared to its contemporary opposite.

Full textAbstract:
The paper considers the methods to improve the efficiency of the business process of repairing power-generating equipment, as one of the main directions for increasing the efficiency and safety of the company activity as a whole. The efficiency of power generating companies is currently determined by the quality of the field-oriented and supporting business processes arrangement. Companies in the power-generating sector have strict environmental and energy security requirements. Accidents at production and transport facilities can cause irreparable environmental deprivations. Also, the failure of the mains sections can completely stymie the work of large settlements, and endanger the life and health of people in the cold season. The performance of the equipment can be impaired as a result of natural causes (corrosive wear, metal fatigue, and other deformations) and due to violation of the operating mode. The good condition of the processing equipment is ensured by the maintenance and repair works performed in time. Company's experience has proven that, for the safe operation of processing equipment, it is necessary to annually appropriate funds in the amount of at least 2% of the initial cost of the equipment. The main focus should be on planning and arranging the processes involved. Safe operation can also mean availability to purchase equipment necessary for production tasks. Many large power generating companies are trying to act under the principle of technological self-sufficiency. It implies the presence of technological developments in intellectual property, as well as production facilities. The implementation of this principle is possible both through the development of own scientific resources, and through the absorption of industrial enterprises. All this gives a competitive advantage to power generating companies, as well as expands the range of services provided.
