Abstract Successful project management boils down to effectively and efficiently managing resources to meet the project's cost and schedule. The ability to manage project effectively becomes increasingly important to recover capital project expenditures in expiring Production Sharing Contracts (PSC) blocks. The longer the time needed for a project to complete, the higher the project capital and the lower the capital recovery. Referring to look back result of several major capital facility projects, the key challenge in meeting the project cost and schedule is related to procurement of long lead materials and key process equipment. In brown field blocks, there is an opportunity to perform reverse engineering by optimally utilizing the excess materials in the warehouse and idle/unused process equipment to solve the key challenges. As additional benefit, utilization of excess materials and idle process equipment will improve inventory management and capital stewardship, since the cost to relocate and modify the equipment are significantly lower than the cost of buying a new equipment. Field X Associated Gas Recovery Project (AGRP) provided an excellent case study of successful reverse engineering approach using excess material and idle equipment in design and construction of a new gas processing facility in brown field block. Field X AGRP is designed to recover and process associated gas from X field to be used as fuel gas for the gas turbines at the internal Power Generation Plant. However, based on lesson learned from similar opportunity in the past, the cost of construction and installation of a new gas processing facility using new construction materials and new process equipment is very high, which is uneconomic at the current oil price environment. Therefore, to make the project economic, the project team shall consider the utilization of available excess material in the warehouse and idle/unused equipment into design basis. Project team conducted assessment to several facilities across the concession area to gather equipment specification data of idle process equipment and the size of available excess materials. The gas processing facility design was reverse engineered to optimally utilize the idle process equipment and excess materials. The utilization of idle equipment and excess material in construction of the gas processing facility has successfully generated cost saving up to 5 times the project cost from avoiding purchase of new equipment and new construction materials. The project successfully recovered associated gas at the rate of 0.5 MMSCFD to be used as fuel to gas turbine and produced 60 BOPD condensate from gas-liquid separation process

Modern road constructions go through a whole range of different loads of static and dynamic nature; therefore, higher-quality materials and solutions are required for the roads of the corresponding class, ensuring their compliance with various climatic, geological and economic factors. Currently used road constructions have different basement, they can be of natural or artificial type. Designing a foundation on a concrete base is considered as the most enduring, however, there are a number of aspects that significantly affect their durability. Improving their reliability and quality is an important promising direction in the study of the use of new building materials. The article shows the possibility of improving the quality of the foundations of road structures through the use of poly-reinforced fiber-reinforced concrete. Compared with metal fiber, polypropylene fiber gives the desired effect of reducing the weight of the structure and the cost. There is a significant increase in the waterproof performance of fiber-reinforced concrete, which is especially important for drainage sections of road construction foundations. The authors determined that a significant improvement in the performance of fibrous concrete is achieved, when the polydisperse reinforcement of the concrete matrix use polypropylene (0.3 %) and steel (1.7 %) fiber. In this case, the first option has an impact on crack resistance, and the use of steel – on strength. Thus, with this ratio of reinforcement with various fibers, a synergistic effect of improving the static and dynamic indicators of fibrous concrete is achieved. According to authors, bench studies of reinforcement of fiber-reinforced concrete structures for the foundations of roads show their high economic efficiency and reduce the cost of 1 m3 of the finished structure to 16 %.

The article presents a special modification of the EOQ formula and its application to the accounting of the cargo capacity factor for the relevant procedures for optimizing deliveries when renting storage facilities. The specified development will allow managers to take into account the following process specifics in the format of a simulated supply chain when managing inventory. First of all, it will allow considering the most important factor of cargo capacity when optimizing stocks. Moreover, this formula will make it possible to find the optimal strategy for the supply of goods if, also, it is necessary to take into account the combined effect of several factors necessary for practice, which will undoubtedly affect decision-making procedures. Here we are talking about the need for additional consideration of the following essential attributes of the simulated cash flow of the supply chain: 1) time value of money; 2) deferral of payment of the cost of the order; 3) pre-agreed allowable delays in the receipt of revenue from goods sold. Developed analysis and optimization procedures have been implemented to models of this type that are interesting and important for a business. This — inventory management systems, the format of which is related to the special concept of efficient supply. We are talking about models where the presence of the specified delays for the outgoing cash flows allows you to pay for the order and the corresponding costs of the supply chain from the corresponding revenue on the re-order interval. Accordingly, the necessary and sufficient conditions are established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to real opportunities to improve the efficiency of inventory management systems by taking into account these factors for a simulated supply chain.

Foundation piles that are made by concrete 3D printers constitute a new alternative way of founding buildings constructed using incremental technology. We are currently observing very rapid development of incremental technology for the construction industry. The systems that are used for 3D printing with the application of construction materials make it possible to form permanent formwork for strip foundations, construct load-bearing walls and partition walls, and prefabricate elements, such as stairs, lintels, and ceilings. 3D printing systems do not offer soil reinforcement by making piles. The paper presents the possibility of making concrete foundation piles in laboratory conditions using a concrete 3D printer. The paper shows the tools and procedure for pile pumping. An experiment for measuring pile bearing capacity is described and an example of a pile deployment model under a foundation is described. The results of the tests and analytical calculations have shown that the displacement piles demonstrate less settlement when compared to the analysed shallow foundation. The authors indicate that it is possible to replace the shallow foundation with a series of piles combined with a printed wall without locally widening it. This type of foundation can be used for the foundation of low-rise buildings, such as detached houses. Estimated calculations have shown that the possibility of making foundation piles by a 3D printer will reduce the cost of making foundations by shortening the time of execution of works and reducing the consumption of construction materials.

Construction materials, traditionally used in process equipment, are today successfully replaced by composite materials. Hence, many pipes are made of these materials. The subject of this study was the influence of liquids on the state of stresses and tensile strengths in the longitudinal and circumferential direction of glass-polyester pipes of a definite structure and known fabrication process. These analyses are of great importance for the use of glass-polyester pipes in the chemical industry. The tensile properties (the ultimate tensile strength and the modulus of elasticity) were tested and determined for specimens cut out of the pipes; flat specimens for the tensile properties in the longitudinal direction and ring specimens for the tensile properties in the circumferential direction. First, the tension test was performed on virgin samples (without the influence of any liquid), to obtain knowledge about the original tensile properties of the material composite studied. Subsequently, the specimens were soaked in alkaline solutions: sodium hydroxide (strong alkali) and ammonium hydroxide (weak alkali). These solutions were selected because of their considerable difference in pH values. The specimens and rings were left for 3, 10, 30 and 60 days in each liquid at room temperature. Then, the samples were tested on tension by the standard testing procedure. A comparison of the obtained results was made based on the pH values of the aggressive media in which the examined material had been soaked, as well as based on the original tensile properties and the number of days of treatment. Micromechanical analyses of sample breakage helped in the elucidation of the influence of the liquids on the structure of the composite pipe and enabled models and mechanisms that produced the change of strength to be proposed.

Definition Of

In a market economy, it becomes important to improve the organization of enterprise management and, above all, the production process, efficient use of financial, material resources and inventories. Effective management of material resources increases profits and provides the necessary investment. To maintain high profitability and liquidity, the management of current activities of enterprises, in particular inventory management plays a significant role. The categorical apparatus of material resources management at the enterprise is considered, the definition of “material resources” is generalized, the definition of "material resources management" is offered, and also the system of material resources management at the enterprise is considered. In the management of material resources at the enterprise there are 2 approaches – logistics and reengineering. The main tasks of the mechanism of management of material resources of the enterprise of building materials are defined. These are: increasing the efficiency of material resources and choosing cheap sources of funding; introduction of new production, resource-saving technologies; minimization of costs for procurement, production and marketing activities; increasing the interest of employees of all services in the effective performance of their duties; product quality management. The analysis of efficiency of use of material resources at the enterprises of building materials which has shown, that manufacture of production is rather material-intensive is carried out. This is evidenced by the share of material costs in the cost of work, and the value of the utilization factor of materials indicates the economical use of material resources in production. Reserves for improving the efficiency of material resources at construction materials enterprises have been identified. The ways of the most rational use of material resources of construction materials enterprises are offered, in particular it is improvement of a design and technology of manufacturing of products, introduction of more progressive norms of expenses of resources, use of substitute materials, and reduction of losses at stages of transportation, storage and industrial use.

The Cost

In the course of research it has been stated that the category of «inventories» is not only the object of accounting, but also the object of management, so the identification of inventories in the assets upon receipt at the enterprise is the initial stage of the accounting process. The process of material and technical base management begins at the stage of searching for suppliers, delivery conditions, formation of the logistics component, determination of transport and procurement costs. There is no doubt that the additional costs associated with these processes will affect the formation of the value of purchased inventories. Therefore, the authors emphasize that the methods of estimating inventories at their receipt and disposal play an important role in accounting, as they affect the formation of the cost of finished goods produced from inventories, and hence the overall financial performance of the enterprise. It should also be taken into account that in accordance with the norms of UAS 9, only the amounts of transportation and procurement costs related to the acquisition (receipt) of inventories are subject to inclusion in the initial cost. In practice, the increase in the value of inventories often includes costs incurred in connection with the internal transportation of inventories on the territory of the enterprise or between its structural units; costs arising from the return of inventories to the supplier; costs for loading, transportation, transshipment and insurance of inventories, finished products (goods), freight forwarding and other services related to the sale of products (goods). Such costs do not affect the formation of the initial cost of inventories. Therefore, the authors highlighted the need for a clear delineation of these costs at specific enterprises with the reflection of provisions in the Order (Regulation) on accounting policies. Most scientists discuss the feasibility of search for a method of cost allocation during transportation, because during this process there can be losses of inventories both within the established norms of natural loss, excessive losses and shortages, as well as spoiled inventories found during asset recognition. The authors gave their own view on the possibility of solving this problem. The solving approach has been presented as well as the peculiarities of the reflection of the distributed transport and procurement costs in the system of accounting have been considered. The situation when the company transport both purchased inventories and those, sold to customers, with its own transport has been considered. In such cases, the authors suggest a method of allocating transportation costs with subsequent allocation to transport and procurement costs, which increase the cost of purchased inventories and distribution costs.
