Zhenhai Oil Refining and Chemical Industry Co., Ltd. 8 million tons / year oil refining expansion project investment control methods and experience The level of investment directly affects the technical economy of the construction project. From decision-making, design, procurement, construction to completion and commissioning of the project, investment control is carried out in the entire process. Therefore, only through the whole process and all-round management can we achieve the goal of investment control. The authors combined with the construction process of the project involved, put forward the project in the decision-making, design, implementation of the various stages of some investment control means. (hereinafter referred to as: Zhenhai Refining and Chemical Company) of 8 million tons / year oil refining expansion project is a national key construction project, the State Planning Commission approved a total investment of about 10.7 billion yuan. The whole project is divided into two steps, the first phase of the project is: through the new part of the device and the transformation of the original refining device, so that the company's primary crude oil processing capacity of 16 million tons / year, the comprehensive crude oil processing capacity of 12 million tons / year. 2001 July the first phase of the project passed the national completion inspection and acceptance. The goal of the second step is to build some new units and expand and renovate the old ones, so that the company's comprehensive crude oil processing capacity will reach 16 million tons/year, and the second phase of the project started in 2000, and it is expected that the whole project will be completed by the end of 2003. The first step of the project can be estimated at about 7.9 billion yuan, the preliminary design of the total estimated budget of 4.3 billion, the completion of the settlement of the actual expenditure of about 3 billion, investment control is more successful. Here, in conjunction with the construction of the project, from several key aspects of the investment control of a few practices, I hope to play a role in the role of a brick to attract jade. First, the project decision-making stage of investment control project decision-making on the entire project investment has the greatest impact on investment control is also the most critical. The focus of investment control at this stage is to reasonably determine the construction scale of the project, select, optimize the process technology routes, to develop the best construction goals. 1. Determination of construction scale and total process route. Zhenhai Refining & Chemical Company is located in the coastal economically developed area, which has a large consumption of oil products. Moreover, it has a deep-water berth in Ningbo Beilun Port that can dock 250,000-ton tankers, and crude oil can be transported directly to the company from overseas by large-tonnage tankers with low freight charges, thus Sinopec Group decided to build Zhenhai Refining & Chemical Company as a processing base for high-sulfur crude oil. It was decided that the new boiler would be a circulating fluidized bed boiler of FosterWheeler Company of the United States, and high sulfur petroleum coke would be used as the fuel for the boiler. This solves the outlet of high sulfur coke and protects the environment. The market price of high sulfur petroleum coke is generally two to one-third of coal, and its calorific value is 1.4 times that of coal, and it is about 0.2 yuan cheaper than purchased electricity when it is used as boiler fuel. 2. Optimization of the total program. Fully rely on the original facilities, based on the transformation of old devices to reduce investment. Fully rely on the enterprise's existing devices, as little as possible to build new devices, new facilities, to "less investment and more output" for the purpose of the Group's repeated organization of expert demonstration will be demonstrated, the original intention to build 12 sets of new devices adjusted to the new 5 sets of renovation of 7 sets of devices, so as to increase the refining capacity of 8 million tons / year of investment than the original new construction program is substantially reduced. Reduce. 3. Step-by-step implementation and rolling development. After the overall goal of expanding 8 million tons/year oil refining project is determined, using the objective reality that the company's crude oil processing capacity increases year by year, it is decided that the whole project will be constructed in two steps. The progress of each sub-project is also scheduled to ensure that the expansion of processing capacity can meet the needs of increasing crude oil processing capacity and the ever-changing market demand. The projects with good benefits will be constructed faster and put into operation as soon as possible; the projects with changes in the market will be slowed down to slow down the peak of capital investment, reduce the bank loans, and lower the interest expenses and construction costs. Second, the investment control of the design stage of the design phase of the investment impact is also very large. Design stage investment control is the goal of the feasibility study report of the investment estimate, investment control focus on the project for specific decomposition and implementation, design, design optimization, focus on technology and economic integration. 1. Good overall design The overall design is done by a total design institute, the whole project is decomposed, a unified code system is established, the design specifications and standards are unified, and the division of labor between the total design institute and other design institutes is clarified. Expansion of 8 million tons/year refining project (the first step) **** decomposed into 43 sub-items, the amount of investment in each sub-item, as the basis for the next step of investment control. 2. Strengthen design management Strengthen the organic combination of technology and economy in the design, and vigorously implement the limit design. Limit design is the last stage of the validation of the amount of investment and the amount of decomposition, approval down to the design profession, and then broken down into units and divisions of the project. The person in charge of each design specialty focuses on the cost decomposition target to control the selection of equipment, the choice of materials and the amount of work. In the design process of the more significant design changes affecting the cost of the project, to make the corresponding economic program comparison, the use of value engineering, from the function and cost of the two angles of the comprehensive evaluation, from which the best program is preferred. 3. Make full use of the original facilities, optimize the design in the original device expansion and renovation design, a large number of original equipment as far as possible not to demolish and rebuild, but to use. Expansion of 8 million tons / year refinery project (Phase I) in five sets of device transformation, a large number of original equipment and facilities have been reused, through these fine-tuning, saving a lot of money. 3. Do a good job in the introduction of key technologies and major equipment localization work in the spirit of "active, steady, reliable and realistic" principle, the domestic has not yet been successfully developed and advanced technology, consider the introduction of foreign. In the expansion of 8 million tons/year oil refining project, the design of 8 million tons/year normalized pressure unit introduces the advanced electric desalination technology of Petrolite of the U.S.A.; the design of 70,000 tons/year sulfur recovery unit adopts the Klaus sulfur recovery and SCOT tail gas purification process, and the construction drawings are designed on the basis of basic design provided by the STORK Company of Holland; and the recycling technology of FosterWheeler of the U.S.A. is introduced. FosterWheeler's circulating fluidized bed boiler technology was introduced, and two 220-t/h boilers were built. When selecting equipment, the company strengthens cooperation with domestic research institutes and manufacturers to carry out the localization design of the relevant projects, and adopts mature and advanced domestic technologies as much as possible to save investment. For example, in the newly built 3 million tons/year catalytic cracking-gas fractionation combined unit, the three major compressor units have adopted localized equipment. Through joint technological research with scientific research institutes, the hydrocracking unit has been modified with domestic catalysts, which saves a lot of foreign exchange. Investment control in the stage of project implementation The stage of project implementation is the stage of real expenses, although the proportion of investment saving is relatively small compared with the previous stages, but the possibility of wasting investment is very big, therefore, this stage should strengthen the management and take strict control measures in all aspects. 1. Equipment and material procurement cost control. Equipment and material cost control is the goal of the preliminary design of the audited budget listed in the corresponding costs, control of the main means for the limit procurement. Zhenhai Refining & Chemical Company takes advantage of its own management to carry out independent procurement of equipment and major materials for the project. The company has established a series of systems for material supply and procurement management, and has implemented a bidding system for the procurement of equipment and materials. By applying the law of market competition, the company selects suppliers with credibility, ability and good service as the object of inquiry, and selects the best ones through bidding. 8 million tons/year oil refining expansion project (the first phase) has a budget estimate of 1.38 billion yuan for equipment, and the actual expenditure is about 1.1 billion yuan, which is a saving of 20%. 2. Bidding and contract management. Zhenhai Refining & Chemical Company actively implements the bidding system in the project construction. The company has established a complete set of project bidding methods, and decides the awardee of the project contract through strict and scientific bidding operation procedures and bid evaluation methods. The construction enterprises with high qualification, good reputation and strong strength are taken as the bidding objects, competition mechanism is introduced, and the construction units are selected on the basis of merit by comparing the quality, schedule and cost. Adhere to the construction drawings for the project bidding, to avoid and reduce the uncertainty and arbitrariness in the process of project implementation to the maximum extent possible; closely formulate the contract documents, and reasonably determine the interface of the engineering contract and scope of works; try to implement the closed-end lump-sum contract, locking the construction cost. 3. Program construction stage of investment control. First, grasp the construction organization and management, and strive to shorten the construction period as much as possible to shorten the construction period, not only can make the project put into operation as soon as possible to produce benefits, but also can save the construction period of the various costs of expenditure. The company has prepared the overall control network of the 8 million tons/year oil refining expansion project, and applied the critical path method (CPM) to determine the schedule of all projects. In the progress control work, the big nodes of progress are taken as the key of control to ensure the implementation of the big node targets. Establish the project coordination system, coordinate the progress relationship between the participating units on a regular or irregular basis, implement the dynamic control of the project progress, and adjust the progress plan in time. Scientific progress planning and effective progress control ensure the realization of the total progress target. Second, optimize the construction program, saving investment construction program is reasonable or not, directly affects the construction project investment, so we should strive to construction program scientific, reasonable and economic. In the preparatory stage of construction, the total plane of the project has a comprehensive consideration of the equipment, materials and large-scale machinery into the field and placed as far as possible to make reasonable arrangements to minimize the number of times to move, the earth to have a reasonable place to pile up to avoid back and forth backward transportation. For those construction difficulties in the renovation project, specially convened a special meeting to discuss the construction organization design and construction technology program, to determine the most reasonable, the most economical construction program, saving a lot of investment. Third, strict control of on-site changes and on-site visas in the construction process, for on-site changes and on-site visas must be subject to strict procedures and approval of the relevant leaders can be carried out, and at the same time to strictly fulfill the signature procedure, all changes and visas to indicate the amount of work and the reason. For on-site changes and on-site visas in violation of the regulations, they are not allowed to increase the cost and not allowed to enter the settlement. By strictly controlling the number of contact sheets, the project cost is effectively controlled. Fourth, the establishment of "project progress console account", strict control of project progress. The establishment of the "project progress console account" as a major basis for each construction unit to pay progress payments, so that the progress of each construction unit to pay the dynamic at a glance. The establishment of the console account takes full account of the characteristics of the large number of projects and the relative concentration of construction units. Set up a desk account first by project, and then by the name of the construction unit, and then detailed centralized reflection of the name of the project has been paid for the preparation of materials, project progress, the supply of materials from the A side of the money and the cost of the project contract, the cost of the project budget, the image of the progress of the project, and so on. Before each progress payment, the construction unit reported by the project management department to confirm the progress of the project and the total cumulative payments recorded in the account with the contract cost of the project, the project's budgeted cost for comparison, and then pay the progress payment, so that the total amount of payment control in the contract cost, budgeted cost, to ensure that the progress of payment in accordance with the actual payment of the progress of payment, and effective control of the project progress payment. 4. Strengthen the "three calculations" management, reasonable determination of project cost. In the budget management, the strict implementation of the project budget, final accounts audit system, compliance and lawful and carefully audit the construction unit to review each construction project budget, final accounts, fair and reasonable to put a good economic pass. For design changes and visa orders need to be signed by the site of the professional construction administrator to confirm the implementation of the project manager audit confirmation before settlement. The company has also established a project write-off system, that is, the project project pre-budget, final account through the project pre-budget department audit, and then sent to the company's investment department for review and inspection, through the financial accounts can only be handled, so as to control the cost of the project more effectively. Through the above measures, the preliminary design construction and installation cost for the expansion of 8 million tons/year oil refining project (the first step) was 1.55 billion yuan, and the actual settlement was 1.34 billion yuan, a saving of 8.6%. And the unforeseen and price difference advance fee of 340 million yuan in the cost category were all saved.
