At the heart of the plant is a Siemens 31-megawatt (MW) SGT-700 gas turbine, the second of the recently uprated turbine type to come on line. The principal guest and speaker at the inauguration was none other than the Peruvian president himself, Alan Garcia Perez. President Garcia expressed himself very excited by the high level of technology applied in the plant, and did not hesitate to encourage other potential customers to follow the example of the pioneering plant owner, Sudamericana, to realize the benefits of cogeneration in their power portfolio. “The partnership between Sudamericana and Siemens was exemplary: the project was a technical success and a benchmark to follow,” says Mr. Enrique Gubbins, CEO of Sudamericana. “This project is not only a good investment for us in reliable technology, it is also a contribution to the environment since cogeneration is a very efficient system of creating energy with the minimum of waste.” steam and gas turbines in their fleet. UTE RIO TURBIO is building a 2 x 120-MW coal-fired power plant in Rio Turbio. With an investment of around 700 million USDollars the Argentinian state intends to exploit the gigantic coal resources to produce electricity for the southern part of the country. This will benefit the development of the region and its inhabitants, the aboriginal Tehuelche people, and also the tourist areas around El Calafate, Punta Arenas and Puerto Madryr. Surplus electricity will be fed into the national grid, the National Interconnection System. Siemens is supplying two SST-900 steam turbines, each with an output of 119 MW. The plant has extreme atmospheric conditions, and will utilize high-tech fluidized bed boilers to burn the low-grade mine coal. As a result, it will be able to achieve European-standard emission levels. Siemens will be responsible not only for the manufacture but also the erection and commissioning of these most southerly steam turbines in the world. 3 Gas turbine breakthrough on fuels containing heavy hydrocarbons Breathtaking glaciers and the wide dry pampas characterize the Argentinian province of Santa Cruz in the south of Patagonia. But the significant coal resources around the city of Rio Turbio are the reason why Siemens is delivering two industrial steam turbines to the southernmost coal power plant in the world. During December 2008, Siemens Energy performed extensive fuel combustion testing for its medium-range (25–47 MW) industrial gas turbines at the manufacturing facility in Finspong, Sweden. The fuels contained artificially high levels of heavier hydrocarbons, and good results were attained for all gas turbine conditions running in DLE (Dry Low Emission) combustion mode. There was no indication of flashback caused by autoignition or high flame speed and the fuel flow in the burner was smooth enough to avoid long residence times for ignitable mixtures to burn “out of place”. In December 2007 the Argentinian Ministry of Mines and Y.C.R.T. (Yacimiento Carbonífero Rio Turbio, the end customer) placed the order with the joint venture UTE RIO TURBIO, comprising the Spanish company Grupo Isolux Corsán and a local company Tecna Proyectos y Operaciones. Grupo Isolux is a repeat customer with several Siemens This is good news, since the proven fuel flexibility means that Siemens can now confidently give documented combustion support to customers. Establishing with certainty the potential for burning these fuels means that Siemens can also reach out to more customers requesting non-standard combustion performance. 2 Steam turbines for the world’s southernmost power plant May 2009 Venture 05 090528_Venture_11_RZ_2.indd 6 29.05.2009 16:09:27 Uhr Focus Wastewater — a suitable case for treatment Wastewater treatment is a multi-billion-euro contributor to the global water-supply industry, where efficiency is literally vital for commercial survival — as well as for public health and well-being. A relative newcomer to the Siemens family, Siemens Turbomachinery Equipment A/S is an acknowledged expert in this niche engineering sector, helping the industry to raise efficiency in terms of both energy usage and wastewater treatment, improving effluent quality and financial health of the utilities. In today’s aggressively competitive environment, the need to apply the most cost-effective industrial engineering solutions is vital for commercial health. The water and sewerage companies, in common with other public utilities and service providers in industrialized countries worldwide, not only face tougher commercial competition, but are also being forced to meet tighter environmental and quality controls. Wastewater, industrial effluent and sewage treatment operations have had to clean up their acts to comply with the latest statutory limits, reducing environmental impact to an absolute minimum. Danish roots in sludge Based in the historic city of Helsingør in Denmark, Siemens Turbomachinery Equipment is a small, specialized company manufacturing and supplying state-of-the-art, single-stage turbocompressors and associated automated control equipment, principally for waste water aeration in ‘activated sludge’ biological treatment systems. Formerly a part of the Kühnle, Kopp & Kausch (K,K&K) organization acquired by Siemens in November 2006, the company has fewer than 270 employees, but is an acknowledged world leader in this niche market, with over 6,000 units installed world-wide and a current annual turnover of around €85 million. The wonderfully-named ‘activated sludge’ system of wastewater treatment involves forcing air through a network of speciallydesigned fine bubble-generating diffusers, installed typically in the base of treatment tanks, raising oxygen levels in the water in exactly the same way as a ‘bubbler’ in an aquarium for pet fish. The oxygenated wastewater stimulates the growth of microorganisms, which subsequently break down the dissolved biological matter, converting it to an inert sludge which, after further treatment, can be disposed of or used for agricultural purposes. The final cleaned effluent can be discharged with complete safety into watercourses or used for irrigation. Drive for efficiency The turbo-compressors manufactured in Helsingør are motor/gearbox-driven machines designed for constant speed and constant mass-flow operation, giving the highest possible operating efficiency. This system, combined with the hydrodynamic bearings fitted to the compressor, means that scheduled maintenance intervals are increased to 100,000 operating hours. Airflow is controlled using a combination of inlet guide vanes (IGVs) and outlet diffuser comprising a series of variable discharge vanes. The electronically controlled 06 Venture May 2009 090528_Venture_11_RZ_2.indd 7 29.05.2009 16:09:27 Uhr December 2009 Venture 07 090528_Venture_11_RZ_2.indd 8 29.05.2009 16:09:37 Uhr Focus "Initial investments included latest 5-axis CNC machines,cutting impeller machining steps from 6 to just 2." Franz Alig, CEO Siemens Turbomachinery Equipment 08 Venture May 2009 090528_Venture_11_RZ_2.indd 9 29.05.2009 16:11:26 Uhr Focus Ensuring maximum efficiency over an extremely wide operating field: adjustable inlet guide vanes and discharge vanes (diffusors) of typical Siemens compressors for aeration applications. IGVs, combined with individually designed impellers, allow each compressor to be customized to meet precise customer requirements for inlet temperature, pressure and flow. At the same time, the discharge vanes enable the output airflow to be controlled from 100 percent to a downturn of just 45 percent. The fully automated control system not only gives the customer very precise control of output airflow, but also enables the system to compensate for seasonal changes in atmospheric conditions, including air temperature, humidity and density, at any given location around the globe. Currently there are eight turbo-compressor units in the range, providing output airflows from 1,500 up to 125,000 cubic meters per hour in power ratings from 50 kW to 3300 kW. Non-stop running The very high level of output turndown provided by all machines in the range means that, by using two similarly-rated compressors in tandem, the operator can vary the output airflow from 45 percent up to the full 200 percent discharge from the twinned installation. This unprecedented control facility allows overall plant-operating efficiency to be raised still further, reducing energy demand and cutting operational costs very significantly. By its very nature, the aerobic treatment of wastewater is necessarily a continuous process, which must operate 24/7, 365 days per year. A typical installation will employ a total of three compressors operating under a cascaded control system, with two tandem units to provide optimum airflow and a third standby machine giving a high level of redundancy. The system also allows all three compressors to operate in rotational sequence to equalize the running hours, the automated system enabling each machine to be shut down and re-started in sequence, without the need to shut down the two remaining operational units or disrupting continuous plant operation. The ABC of controlled savings As aeration represents well over 50 percent of the total energy demand of an entire wastewater treatment plant, any possible savings through increased efficiency offer a major advantage for the operating utility. The combination of compact design, dual-vane control and constant mass-flow in Siemens' Helsingørmanufactured turbo-compressors yields world-beating mechanical efficiency of some 85 percent, reducing energy costs significantly. Nevertheless, where the aeration system is operated under simple open-loop manual or semi-automated control, energy can be wasted through excessive airflow and high dissolvedoxygen levels. Alternatively, biological action and treatment will cease completely if levels May 2009 Venture 09 090528_Venture_11_RZ_2.indd 10 29.05.2009 16:11:53 Uhr Focus Besos' wasterwater treatment plant near Barcelona, Spain. The company owns 16 wastewater treatment plants with a total capacity of 800,000 inhabitant equivalents, serving 52 municipalities with 500,000 inhabitants alongside the Besos river. Showcase Cleaning up in Spain are allowed to fall too low, leading to plant breakdown and major environmental problems. However, Siemens' aeration units are designed to operate with twin-track automation, combining electro-mechanical systems and a specially developed Air-Biological Control, or ‘ABC’ system, in a fully integrated control loop. Oxygen probes measuring dissolved O2 levels together with airflow and discharge-pressure controls are installed in conjunction with an adaptive set-point pressure control to provide optimum aerobic treatment conditions. Over a typical 20-year life-cycle where energy usage amounts to between 95 and 97 per cent of the total running costs of an aeration unit, Siemens' dedicated focus on system reliability and energy efficiency is enabling water treatment utility companies to slash their energy bills by up to a staggering 40 percent, compared with conventional systems from other suppliers. Pay as you benefit At a time when the availability of credit for capital equipment replacement projects is at an all-time low, it takes some creativity to promote advanced technology. In order to ease investment decisions in favor of Siemens- based upgrades to existing obsolescent and inefficient equipment, Siemens Financial Services offers a dedicated financing scheme. Simply put, it lets customers pay for their new, energy-efficient solution with the money the solution saves them in terms of energy costs. Typical payback times on capital expenditure are less than 5 years, after which customers can fully enjoy ownership and benefits of the Siemens solution over its remaining service life of an averaged 15 years. The wider perspective While Siemens' aeration equipment and technological solutions have become the systems of choice throughout the wastewater treatment industry, applications are not just limited to this niche market, but include a number of fermentation processes in yeast and secondgeneration biofuel production, as well as onshore fish farms. With further control-system technologies already in an advanced stage of development, this newest member of the Siemens Oil and Gas business is set to meet the challenges and demands of the industry for even higher water quality, energy efficiency and plant reliability, for the foreseeable future. While design parameters, theoretical facts, figures and colorful presentations may provide a certain degree of assurance, real-life case-studies can help to convince even the most skeptical of engineers about the true performance of systems and equipment. Venture takes a close look at a recent installation where Siemens is helping a water utility save money — and the environment. Located some 30 km north of Barcelona in Spain’s Catalonia region, the city of Granollers is a major commercial and industrial manufacturing center, despite an agricultural history underlined by its name, derived from the Latin word for grain. Serving the city together with the surrounding municipalities of Canovelles, Les Franqueses del Vallès and the neighborhood of La Torreta in La Roca del Vallès, the Granollers wastewater treatment plant is owned by the locally based Besos company. Although the plant is independently operated, Besos is responsible for quality control, maintenance and all research and development covering not only the Granollers plant, but also the fifteen other similar regional treatment plants owned by the company. 10 Venture May 2009 090528_Venture_11_RZ_2.indd 11 29.05.2009 16:12:09 Uhr Focus The bubbles, the Siemens solution, and a happy customer: "After a full 9 months of continuous operation, overall performance has exceeded our expectations. The new compressors operate faultlessly, and energy savings are at around 30 percent." Angel Freixó i Rey, responsible for R&D&I at Besos' Granollers plant. Meeting expectations The Granollers plant is capable of treating around 30,000 cubic meters of industrial and domestic wastewater per day, sufficient to meet the requirements of a population of some 200,000 people. The plant layout is designed to provide n+1 redundancy, with two Siemens aeration-compressor units in continuous operation and a further standby unit to enable each machine to be taken out of service in rotation for routine maintenance. As energy use comprises some 30 percent of total plant-operating costs, second only to the expense of sludge disposal, Besos’ choice of aeration treatment system was heavily dependent on its energy-saving potential as well as both its performance and reliability. Based on the technical specifications in Siemens' original proposal, possible energy savings were estimated to be between 20 and 25 percent, and three units were supplied together with Siemens’ Air-Biological Control (ABC) to the Granollers plant. Following the subsequent installation of the Siemens compressors and controls, Besos has confirmed that, after a full 9 months of continuous operation, overall performance has exceeded expectations, the new compressors providing faultless operation coupled with energy savings running at around 30 percent — an outstanding result made possible by the unique combination of mechanical and biological control systems. New moves Underlining Besos’ satisfaction with the performance of the new compressor systems and the very significant reduction in running costs at its Granollers treatment facility, the company is now looking to install energy-saving Siemens aeration compressor-units as standard at all its other 15 wastewater treatment plants in the region. The move to standardize with Siemens systems will not only reduce total energy use, but will reduce through-life cost of ownership over the company’s entire portfolio, through reductions in both spares and maintenance requirements. In an ideal scenario where wastewater treatment plants throughout Spain were to be re-equipped with high efficiency Siemens aeration systems, daily energy usage would plummet by a minimum of 480 megawatts, equivalent to around half the output — and half the CO2 — from a billion-pluseuro coal-fired electricity generating plant. Based on a mathematical model of optimum aerobic conditions for the bacteria used in biological wastewater treatment, Siemens' Air-Biological Control (ABC) provides for a further boost in energy savings by adding a new level of accuracy to the aeration control system. May 2009 Venture 11 090528_Venture_11_RZ_2.indd 12 29.05.2009 16:12:46 Uhr The road ahead A seasoned oil and gas man, Tom Blades joined Siemens at the beginning of the year as President and CEO of the Oil & Gas Division of Siemens Energy. Venture sought his impressions and ideas on the position and direction of the oil and gas industry in general and Siemens’ oil and gas business in particular. 12 Venture May 2009 090528_Venture_11_RZ_2.indd 13 29.05.2009 16:13:08 Uhr Faces Venture The past year has seen a roller-coaster ride in primary energy prices and now we’re talking global recession. In such times of change, taking the post of CEO of a company delivering to the oil and gas industry must be something of a challenge? Tom Blades Yes, it’s certainly a challenge, but is it really a time of change? I think — and my peers in the industry seem to agree — that both mid-term and long-term nothing has actually changed. Price-swings like these are not uncommon in an industry which has always been volatile. However, I do think that the speed, size and perhaps the duration of the swings are increasing and many people in the industry are concerned with the speed of the current downturn. I believe what we’re seeing here is a temporary situation. But prices will definitely recover and will almost certainly rise higher than before. In the meantime we have to cope with the current situation, which is that we’re back to the same oil prices as in 2004. Unfortunately for suppliers, the next 12 months will see the major players trying to balance 2004 prices and 2009 costs. Venture Coming afresh from a very different company, how do you view Siemens’ current profile in the oil and gas industry? Tom Blades From an outside perspective, Siemens has a great image as a long-established supplier of high-tech industrial systems, components and equipment. On the other hand, it is still developing the high profile as a major player in the oil and gas business needed for the credibility to offer specific solutions to customers in this sector. That’s part of our challenge: to move up the decision-making tree, to transform from component supplier to genuine partner with the customer. Venture Isn’t there a big variation in how the Siemens ‘brand’ is seen by different customers in the oil and gas industry? Some have no brand recognition; others refer explicitly to the Siemens brand value. Tom Blades Yes, that’s true. Customer response is likely to include the reliability of the Siemens brand as well as the products themselves. When the product is supplied by a "The leopard may change its name but it doesn’t change its spots." company with a reputation for reliability and service, the customer is buying a level of confidence. But I would venture to say that, although Siemens is relatively well-known and respected by middle-management as a supplier to the oil and gas industry, brand recognition has not yet reached board-level. That we have to change. That has to happen. Venture With regard to the oil and gas industry: where was Siemens five years ago, where is it now — in terms of say, structure, investments and quality — and where do you want it to be five years from now? Tom Blades Well, of course I have only a general impression of the company’s previous position, but if I try to describe Siemens Oil & Gas as it was then, it would be essentially as a sales and marketing channel for Siemens industrial products, with efforts directed at selling components and equipment to oil and gas customers. Today, five years later, we manufacture and market three product ranges — steam turbines, gas turbines and compressors — and have set up an oil and gas industry solutions business including electrical and automation equipment. The objective is that — without neglecting the existing mature markets such as power generation or the chemical industry — we use the all-fields solutions approach to increase our share of the global oil and gas market, because that’s where we see the opportunity for growth in the coming years. We already have a major slice of the mature market that we need to defend, although it is not likely to grow significantly over the coming years. Added to that we have the oil and gas business where we see excellent potential for future growth, which is why this division was formed in the first place! So not only do we have our own products, we also have the ability to provide end-to-end solutions for our customers. And this sector, where we are expanding fastest, will provide ‘pull-through’ May 2009 Venture 13 090528_Venture_11_RZ_2.indd 14 29.05.2009 16:13:15 Uhr Faces "Even in today’s financial climate we are able to take ‘make-or-buy’ decisions on a company level." for a whole range of other systems and equipment — such as transformers, switchgear, variable-speed drives and process-control systems — all supplied from businesses within the Siemens family. And that, I think, will lead in turn into other relevant technologies and products, taking us from a product sales and marketing organization, to being a real supplier of end-to-end solutions. Venture: So strategic shopping is not yet over? Tom Blades No, absolutely not. I think, in fact, that even in today’s financial climate, one of Siemens’ great strengths is that we are able to take ‘make-or-buy’ decisions on a company level. Of course we aren’t immune to the current global downturn, but we are faring better than most of our competitors and are actually seeing improvements in many areas of the business. Venture: A recent customer satisfaction survey showed that the Siemens brand is recognized for its reliability, and the quality of its manufacturing and engineering technology, but there must be other areas with room for improvement. How might you tackle these? Tom Blades Well, one of the findings of the survey was that we’re not responsive enough, which I believe is not just a human factor but more of an organizational issue. As a newcomer, I don’t think Siemens is the easiest company to understand. After four months, I’m still learning how we’re organized. What I’m seeing is that, although we have great resources, they’re not always aligned or tuned to each other. It’s a bit like an orchestra; if the tuning or rhythm is a bit ‘off’, you’ll hear a difference and I think that’s maybe what our customers are referring to in terms of responsiveness. Venture: And how do you propose to retune the orchestra? Tom Blades Well, the strategy will depend, of course, on guidance from corporate headquarters, in terms of what is possible and what makes best business sense. First and foremost, however, we have to work to get closer to the customer, perhaps along the lines of the company’s Brazil Chemtech organization. There we have quite a significant engineering organization that’s very close to its customers in that country, with local resources and local personnel and very well managed. This has resulted in tremendous customer confidence, not necessarily to buy products but to solve real problems. After all, it is easier to do business with partners and friends than it is with strangers. Venture: Are there any other examples of similar ‘Best Practice’? Tom Blades Yes, we have a similar situation in Houston, Texas, through another Siemens company called Berwanger, where we are ramping up efforts in the same way. The company operates in exploration, refineries and haz-op analysis in complex chemical or refining processes where it is absolutely essential to have an intimate knowledge of the customer’s process from every angle. For that kind of company, you need confidence in the people before you even consider giving them any business. I’m happy to say we’re in that position and have something we can build on. We also have a group in South-East Asia with a small number of people in Kuala Lumpur and Singapore, and we need to take the operation forward to turn the small group into a critical mass. Venture Regarding the oil and gas industry, what do you see as the biggest areas for growth? What other strategic areas or applications would you like to focus on and how might Siemens be able to help? Tom Blades The leopard may change its name but it doesn’t change its spots. Our mature market for rotating equipment is one where we need to maintain our position, retaining and growing our market share wherever and whenever possible. I definitely see ‘green’ power generation as a major growth area. Solar thermal is a very attractive direct market for us, as is cogeneration with the turbines in our range. Venture: Apart from these more ‘mature’ market areas, where do you see future opportunities for the oil and gas business? Tom Blades My 30 years in the oil and gas industry have taught me that it really is a cyclic business. I think this is the fifth time I’ve seen oil go from sky-high prices to a slump followed by a full recovery! It’s not really growth that’s driving the business; it’s depletion of resources. Technologies such as steam or water injection, gas compression and advanced subsea systems are all areas which are becoming economically viable as oil prices increase and are all technologies in which Siemens is active and can provide solutions, both now and for the future. 14 Venture May 2009 090528_Venture_11_RZ_2.indd 15 29.05.2009 16:13:15 Uhr Resumé Age: 52, born in Hamburg, Germany Nationality: British, bilingual upbringing (German and English) Family: Married, two children Hobbies: Golf, diving, and triathlon Vocational training: Electrical engineer Career history 1978: Schlumberger, ultimately 1993–1996 Vice President and General Manager Schlumberger/Geco-Prakla 1996: NUMAR Corporation, COO and Executive Vice President 1997: Halliburton, Executive Vice President 1998: SPECTRO, President and CEO 2004: CHOREN Industries, President and CEO Since 01/2009: Siemens Energy Sector, CEO Oil & Gas Division 090528_Venture_11_RZ_2.indd 16 29.05.2009 16:13:25 Uhr The Duisburg Mega Test Center, revisited Back in July 2008, Venture reported on the inauguration of the stunning new Mega Test Center — the MTC — built as part of the facilities at Siemens Oil & Gas international headquarters at Duisburg, Germany. Now, just one year after its official opening, we re-visit the giant new Center to see if reality has met expectations. Designed to provide comprehensive test facilities for compressors and their associated drive systems in all sizes including the largest machines currently designed and built by Siemens the company’s giant Mega Test Center has just celebrated its very first ‘birthday’. Inaugurated in March 2008, less than two years after the first earth-moving machines rumbled onto the site, the MTC has seen a full twelve months of engineering activity and now presents a rather different appearance to the vast, almost-empty building which welcomed the crowds of invited guests during the opening ceremony. Heavyweight testing The past year has been one of continuously increasing activity, with comprehensive testing successfully completed on no fewer than seven compressor strings. While at first glance this may not sound like a particularly impressive number, bear in mind that these ‘strings’, comprising the 090528_Venture_11_RZ_2.indd 17 complete steam and electric drive systems, massive multi-stage compressors and all ancillaries, including lubrication and coolant systems, controls and instrumentation, can be as large as a good-sized house, weigh in at many hundreds of tonnes and consume enough energy to power a small town. Two of these seven super-sized heavyweights from the Siemens stable, developed and built at Duisburg and tested in the new MTC, were designed for air separation applications. Two further machine-strings were built for use in natural gas liquefaction (LNG) plants and the other three compressor strings to complete their test-regimes in the new facility were designed for continuous-process applications in the petrochemical industry and for gas liquefaction. Making it big in China China’s huge coal deposits not only make this black gold the most important source of energy in the country, but new technologies also 29.05.2009 16:13:38 Uhr Monitor 1 enable the production of liquid fuels and a very wide variety of chemicals from basic coal feedstock, offering increasing independence from crude oil and natural gas. The two massive air-compressor-trains, which were assembled and recently completed comprehensive operational testing at the MTC, were ordered by Air Liquide (Hangzhou) for the Ningxia Coal Industry Group in the People’s Republic of China, under a contract worth some 25 million euros. Currently being installed in what will become the world’s largest polypropylene plant, operated by Shenhua Ltd and due to start production later this year, the two giant machine-trains each consist of an STC-SR axial-radial air compressor, an STC-GV (H) final-pressure air compressor, and an SST-600 steam-turbine drive from Siemens’ Görlitz manufacturing center and all ancillary systems and controls. Operating rather like enormous refrigerators, the compressor trains will be used in air separation plants and will each produce 3,000 tons of oxygen per day. With a capacity of 700,000 cubic meters of air per hour, the machines are themselves among the largest of their kind ever built. A third compressor string, built at Duisburg and assembled and tested in the new Center, is also being shipped to Shenhua 2 International’s Yinchuan coal-tochemicals polypropylene plant. Like the previous two machines it comprises an STC-GV six-stage integrally geared compressor with an SST-600 steam-turbine drive, but this third monster machine train will form part of the main fluidized-bed gasification process, where coal is converted into synthetic-gas feedstock. Designed to compress 82,300 cubic meters of carbon dioxide per hour to a final pressure of 58 bar, the entire machine underwent efficiencytesting at the MTC using CO2 test-gas in a closed-loop configuration, prior to being readied for shipping. Planned expansion With the Mega Test Center currently operating at close to maximum capacity, with some 20 machine strings either on test or being assembled, as one mega-machine is shipped out another is being readied to move in. While some final commissioning work on the existing building is still being carried out, plans to expand the facility are already in place. This will not only include increasing the number of highly qualified test engineers at the Center, but also extending its capabilities. Believed to be the only facility of its kind capable of supplying steam at 100 bar/500°C at flow rates up to 7,500 cubic meters per 3 4 hour to test advanced prototype machines, it is planned to increase flow rates still further to meet customer requirements for even larger and more advanced steamturbine drives. A separate gasturbine test facility is also being planned, using shared facilities including cooling systems, while test facilities including large loadbanks are scheduled to meet future needs for complete steam and gas turbine generator sets. With visitors from major international customers from the oil and gas industry continually impressed with the scale and range of expertise available at the MTC, reducing on-site commissioning times and reducing customer risk, its ‘mega’ future looks set to continue. 1A three-case (low/mid/highpressure) steam-turbine-driven compressor string for an olefin plant in the Persian Gulf region. 2During test drive: One of two massive air-compressor trains currently being installed in what will become the world’s largest polypropylene plant, located at Yinchuan in China’s coal-rich Ningxia region. 3A CO2 compressor for the main fluidized-bed gasification process at the Yinchuan propylene plant. 4Main refrigerant compressor trains for an Indonesian mid-size LNG plant — an emerging application in the oil and gas industry.

As part of the company’s multi-million-USD strategic plans to boost productivity and operational efficiency, the company recently installed a comprehensive Visualized Operations Intelligence System (VOIS) at its principal refinery and production complex at Ulsan, based on Siemens’ SIMATIC IT XHQ. In full operation since February this year, the new VOIS has already proved so successful that SK Energy is looking to extend the system to its other business units. With a history spanning more than 40 years in the oil, gas and petrochemicals industry, this South Korean-based company, originally founded as a state-owned enterprise, not only established the country’s very first oil refinery but has grown massively over the past four decades. Operating in the private sector since 1980, SK Energy has become Korea’s leading private-sector producer and supplier of olefins and petrochemical products. The company manufactures well in excess of 240 million barrels per year of refined petroleum products, in addition to supplying 35 percent of the domestic demand; around 100 million barrels are directly exported, to a value in 2007 equivalent to more than 16 billion USD (€ 12 billion). Currently one of the largest primary energy companies in the Asia-Pacific region, SK Energy is now operating on an increasingly global scale. The company is currently either exploring or producing from wells in 27 oil and gas ‘blocks’ in 15 countries worldwide and has proven reserves exceeding 500 million barrels of oil-equivalent (mboe). Going for growth The company’s principal refining and petrochemical processing operations are based at its refinery complex at Ulsan. Located on the coast 70 km north of Busan in the southeast of the country, the refinery, one of the largest of its kind in the world, with production peaking in excess of 840,000 barrels per day, forms a major part of the country’s main industrial area — the Ulsan Industrial District. In addition, SK Energy also owns and operates a second major refinery at Incheon, on the opposite coast some 315 km northwest of the Ulsan complex, having acquired Incheon Oil in 2006. SK Energy is currently undertaking the third phase, from 2008–2010, of its long-term strategic plans for international expansion, increasing its competitiveness in key petroleum and petrochemicals businesses in global markets. It is already supplying markets in China, the US and Europe. This expansion, maximizing shareholder value and laying the groundwork for this latest phase of rapid growth, is based on the optimization of the May 2009 Venture 19 090528_Venture_11_RZ_2.indd 20 29.05.2009 16:14:26 Uhr Spotlight Ulsan Complex Overview Offsite Overview From tanker jetty through processing to storage and offloading, VOIS aggregates operational data from just about any unit at SK Energy's vast Ulsan Complex. Inventory Overview company’s petroleum and petrochemical businesses, which includes raising productivity and operating efficiency at its Ulsan Complex. Raising the game Product Inventory Tag Details Although extensive IT, business and process monitoring systems were in place throughout the complex, these comprised discrete, individual ‘point’ or ‘silo’-type applications, each designed to provide data covering a specific function or area of application. Although the information was recorded, these disparate systems were unable to provide timely information to operate as decision-making tools, either for operators or for managers. Time taken for the extraction, aggregation and physical interpretation of data from discrete systems made it both unreliable and unsuitable for real-time intervention. The existing scheme of things was good for ‘post-mortem’ analysis only. As SK Energy’s Senior Vice President Mr. Sung observed, “In order to become a world-class company we realized we had to implement industry best-practices by removing the functional and informational ‘silo’. In addition, we needed to communicate corporate objectives to our engineers and support them with accurate and timely information.” “Our people are smart and giving them the right tools empowers them to take the right decisions at the right time. This helps to improve efficiency, productivity and profitability.” Profit generator Before making the necessary significant investment in any new state-of-the-art system, the company evaluated a variety of competing 20 Venture May 2009 090528_Venture_11_RZ_2.indd 21 29.05.2009 16:14:34 Uhr Spotlight Ulsan Complex Overview Area Overview Should any unit run out of spec, VOIS issues an SMS or e-mail alert to ensure immediate response and problem-solving.

It became clear that Siemens’ Operations Intelligence suite (XHQ,) is the most widely used and “best in the class”. Starting with Chevron Texaco's implementation in 2002, XHQ has become the system of choice for an increasing number of industry-majors worldwide. These include Exxon Mobil, Saudi Aramco, Hovensa, Caltex, Singapore Refinery and Idemitsu Kosan. In all these instances the new operations intelligence solution from Siemens was shown to have provided fundamental and sustained operational improvements. According to Idemitsu, one of the largest refinery and petrochemical companies in Japan, additional profits amounting to 800 million Yen (€ 6.1 million) were reported from its Hokkaido refinery within one year of implementation of XHQ solution and attributable directly to it. In recognition of the outstanding value generated by the solution, in 2007 the Japanese Institute of Information Technology (JIIT) presented Idemitsu with its highest award. Giving VOIS to Ulsan Following the evaluation of possible systems, SK Energy opted to implement the Siemens Operations Intelligence solution XHQ throughout its Ulsan Complex in June 2008. Visualized Operation Intelligence System (VOIS) is the name of the project which pursues the vision “No Visualization — No Movement — No Improvement!” The implementation of the complex-wide system was completed in October 2008 within four months, despite some minor issues, such as the need to translate some information from Korean into English as the working language. After internal reviews and minor modifications, the solution was formally released to the complete user community in February 2009. Commenting on this remarkable achievement, Mr. Sung stated with understandable pride, “Our SK energy people, our local partner and the guys from Siemens formed a dream team!” The system covered the majority of functional areas and around 70 process units in both the refinery and the petrochemical plant, providing information for more than 1000 users. The company describes the VOIS as a user-friendly visualization tool, enabling users to obtain essential information for day-to-day use for locations and functional areas including Offsite, Onsite, Process, Operations and Product Management. Users range across the May 2009 Venture 21 090528_Venture_11_RZ_2.indd 22 29.05.2009 16:14:50 Uhr Spotlight "No visualization, no movement, no improvement!" — Hag-Yong Sung, Senior Vice President Production Management & Strategy at SK Energy entire workforce, with data shared by some 140 board-level directors and senior managers, to around 1000 supervisors, engineering staff and plant operators, enabling the whole plant to be monitored continuously and at many levels. Panoramic view Combining and aggregating data from multiple sources around the entire refinery and associated petrochemical process plant, the new XHQ-based VOIS is designed to present vital operational information visually in a meaningful, contextualized manner — on demand, with appropriate security — at the right time, to every user at the plant, from plant operator to CEO. The system is able to meet the differing needs of the very large number and variety of users. It provides a bird’s eye overview of the plant and processes, with the option to drill down to the lowest level of detail, through multiple layers of information, to access necessary details of a functional area or individual process. It allows the users to concentrate on their work rather than spend time creating reports or mining for data. Wider perspective, better understanding Allowing information to be shared widely has also improved interdepartmental communications and helped users to relate better to each other, providing greater understanding of different job-functions. The requirement for minimal training combined with the ability of the user-friendly system to paint the user’s display screen in just seconds, speeds up and simplifies very significantly the flow of information throughout the company. It also allows potential problems to be easily identified and monitored, decisions to be taken and actions implemented without delay, preventing unscheduled downtime, optimizing operations and increasing overall plant efficiency. Instead of relying on ‘post-event’ reports to provide information on alarms, control malfunctions or set-point excursions, the XHQ-based VOIS not only provides on-screen information on the user computer, but also automatically sends SMS messages or emails to the relevant people, enabling immediate action to be taken. Present benefits, future advantages While the newly installed system has been extremely well received by the entire user community of the Ulsan site and is rapidly becoming a de facto mission-critical application, its benefits are also becoming more widely 22 Venture May 2009 090528_Venture_11_RZ_2.indd 23 29.05.2009 16:15:05 Uhr Spotlight "Our SK Energy people, our local partner and the guys from Siemens formed a dream team." apparent. Its ability to provide rapid and visual display allows the user to both see and understand what is happening in the next (downstream) or previous (upstream) process is not only highly beneficial for operators and managers within the refinery and petrochemical plant, but also enables fast and effective cross-functional communications between partners throughout the supply chain, such as the production departments and the marketing functions. In addition to increasing the effectiveness and utilization of existing plant-wide information and business systems, Siemens’ XHQ has actually reduced their loading and has made quite significant changes in the way that the company will undertake extensions or additions to its existing information networks. Linking future modifications to the XHQ-based VOIS will leverage significant advantages for new projects. A number of smaller IT projects have already been moved, integrating them with the VOIS. Building on success Although the system is already providing direct major cost-saving benefits, it has been up-and-running for only a few months (from February 2009) so efficiency improvements and cost-savings have not yet been quantified with any accuracy. Nonetheless, Mr. Sung appears to be more than satisfied with results to date, commenting, “We confidently expect to achieve returns of many times the capital cost of the project in these first few months of operation alone.” In fact, the VOIS project has proved so successful that the company is now looking to install a second plant-wide XHQ system at the Incheon refinery complex and throughout its headquarters operation in Seoul. In addition, SK Energy has indicated that it sees major longer-term advantages in implementing the system to integrate information from multiple business units, eliminating functional and IT-imposed boundaries in exactly the same way as at the Ulsan Complex. Clearly, another satisfied customer and another winning solution from Siemens.
