Wartsila

• 	Wartsila As a solution in powering of oil and gas field for operators of oil and gas deposits we offer Wartsila company gas-piston power plants with a capacity from 4 to 300 MW. More than 175 years of experience make the company a leader in the field of power supply for the sea and power markets with an emphasis on technological innovations and general efficiency. Every third vessel in the world has Wartsila equipment, because clients trust to this engine reliability and quality. To date the company employs 18000 persons and carries out 100 projects per a year and provides service 24/7 worldwide. Today for Kazakhstan is important the development and modernization of gas and oil pipeline routes in this connection Wartsila engines can be the complex solution of problems in a choice of a drive for pump and compressor stations.   It is no secret that one of the most urgent challenges facing the oil companies, is the utilization of associated petroleum gas (APG). In the majority of most cases gas is flared, complicating an already difficult environmental situation in the areas of oil fields. Meanwhile, the use of associated petroleum gas in the energy sector can not only improve the environmental situation, but also solve the problem of heat and power supply of oil companies. Specificity of associated gas extraction is that it is a by-product of oil production. The inability to use it is due to unreadiness of appropriate infrastructure for the collection, preparation, transportation and processing of associated gas. Use of associated petroleum gas as fuel in Wartsila gas-piston power plants for the decentralized power supply is the competent decision of the thrifty executive manager. Associated gas is characterized by instability of its composition. Depending on its quality associated gas requires gas conditioning in various degrees of complexity. Due to the unique method of using an injection of pilot liquid fuel for ignition, associated gas can be used as fuel both for electric power generation and for driving mechanical equipment in the oil fields.   And if the quality and quantity of gas varies, then there is this mode of "fuel fraction" - the innovative technology of Wartsila, which has made a revolution in the field of a flexible choice of fuel. And what was previously considered as a disadvantage now is an advantage. Gas-piston units completed with heat recovery boiler make it possible to exploit equipment in a cogeneration mode, i.e. for the heat and electricity combined production. This heat and power mini-plant can produce heat and electricity locally, directly at the point of consumption. A significant advantage of a heat and power mini-plant is to minimize losses from the transfer of heat and electricity due to the location of this mini-plant in the immediate vicinity of the energy consumer. Combined production of electricity and heat gives the overall 90% - 92% efficiency of plant with minimal environmental pollution. This is possible because during the operation of gas-piston engine the waste heat is utilized due to fuel saving achieving approximately 40% in comparison with separate production of electricity and heat. With the constant increase of electricity tariffs and increase of their share in the cost price of production from the economic point of view the use of associated gas to produce electricity and heat can be considered as more than reasonable. Taking into account the high energy consumption of oil production in the world there is widespread use of associated gas in the gas-piston power stations (GPPS) to generate electricity and heat for the needs of oil production. Gradually, this experience is being introduced in our country, and TURKUAZ MACHINERY is ready to make its contribution to this process.Прослушать

• 	Modular Solutions The main goal of modularized design is to achieve highest possible quality with a reasonable cost, thus ensuring better overall feasibility for the power plant investment. The key elements are standardised process solutions, component selection and interfaces, and effective, as well as flexible, change management. The focus of modularization is around the engine and inside the power house, even though the modules can be found in most locations, starting from the unloading of fuel, lubricating oil and other process-related items. Rapid installation time is one of the main benefits of using modules. It has been calculated that the use of non-standard modules compared to standard modules could increase delivery times by a factor of 1.5. Prefabrication in combination with the use of well-proven components from the best suppliers ensures consistent high quality and less complex specifications during the procurement phase. Compact and predefined sizes for container transportation make transportation simpler and smoother. With the modular design most components can also be standardised, thereby offering clear savings both in design and construction stage as well as in operation stage of the power plant. Using portfolio modules leads to higher documentation quality during the tender phase. Through the stricter control it gives over the manufacturing, cleaning and painting processes, as compared to carrying out this work on site, modularization also has a positive impact on the environment.

• 	Automation Wärtsilä Power Plant Automation is based on the following building blocks:  WOIS (Wärtsilä Operators Interface System) is the operator’s workstation, for process displays, control actions, trends, alarm and event lists  WISE (Wärtsilä Information System Environment) is the workstation for reports, logbook, electronic documentation and 3rd party interfaces  UNIC is the engine embedded control system, handling all the control, monitoring and protection functions of the engine, together with the PLC  PLC based process control system handles all the control, monitoring and control functions of the genset and plant equipment  Remote connection provides a secure internet or satellite link, to give remote access to the information in the WOIS and WISE systems  Condition Based Maintenance (CBM) reporting system, is a subscriber based condition evaluation and reporting system created by Wärtsilä experts. The systems have been developed with complete integration, and have clear and easy user interfaces providing a uniform interface and logic for the operators. The latest automation equipment and innovations are introduced based on systematically field tested solutions. Wärtsilä Power Plant Automation provides a complete plant management solution with standardized modules, which can be tuned to the operator´s particular needs.

• 	Spark-Ignited Engines (SG) The SG engines are spark-ignited lean-burn otto cycle gas engines. In this process, the gas is mixed with air before the inlet valves. During the intake period, gas is also fed into a small prechamber, where the gas mixture is rich compared to the gas in the cylinder. At the end of the compression phase the gas/air mixture in the prechamber is ignited by a spark plug. The flames from the nozzle of the prechamber ignite the gas/air mixture in the whole cylinder. After the working phase the cylinder is emptied of exhaust and the process starts again.

• 	Fuel Program Wartsila is an engine operates on random fuel types from natural gas till fuel water emulsions.
