carried roughly 52 million passengers and 7.5 million vehicles across the Bosporus on five different routes with crossing times of between one and two hours. The company does exactly what it says on the name plate – IDO stands for Istanbul Deniz Otobüsleri, which means “Istanbul Sea Ferries”. Its ships are named after important personalities from the turkish history.

biggest engines for largest ferryThe largest of them, the ferryboat Orhan Gazi built in 2007, sails twice a day in winter and up to four times daily in summer across to the town of Bursa. Built by Austal, its capacity is enor-mous. Within its overall length of 88 meters, it can accommodate up to 1,500 passengers and 300 cars. So it is no surprise that below decks in the engine room there are four of the biggest engines made by MTU – 20-cylinder Series 8000 units that deliver as much as 9,100 kilowatts of power each and propel the craft at speeds up to 35 knots. “The engines run very economically at that speed. That is especially important to us,” expounds Nurettin Kayabası, Marine Engineer Superintendent at IDO. The ship also has two Series 60 gensets each generating 600 kilo-watts for the onboard power supply. The level

The Turkish economy is growing. The country is already among the leaders in many industries. By 2023, the 100th anniversary of the founding of the Republic, Prime Minister Erdogan aims to have established Turkey as one of the top ten national economies in the world. The key to that ambition is energy – because growth demands power. But due to the rapid rate at which de-mand is rising, the power grid in Turkey is not al-ways stable. MTU Onsite Energy is a sought-after partner for gas-engine continuous-duty genera-tors and diesel-driven emergency backup gene-rators in the Turkish private sector. “To date we have installed 105 megawatts of system capa-city supplied by MTU Onsite Energy, and we ad-ded 55 units in the last year alone,” reports Ali Güzel, Director of Sales and Marketing at MTU Turkey. The company is valued by end clients as a system supplier of tailor-made emergency and continous power supply solutions, offered by the Series 2000 and 4000 gas engines. According to the Turkish Electricity Transmission Company, the electricity demand in Turkey will rise by six per-cent a year between 2009 and 2023. The aim is an installed capacity of 125,000 megawatts. By comparison, the figure was 54,423 MW in 2010.

In Istanbul especially, the energy need is acute. This is where most of the foreign companies have established their bases. One fifth of the Turkish population lives here. And anyone who has ex-perienced this city understands its attraction – lively and animated, a noisy mixture of oriental flair and western lifestyle, Istanbul has visitors in-stantly under its spell. No other city in the world spans the junction of two continents – Europe and Asia. Just looking down on the city from an airplane, the dominant role of the Marmara Sea is clearly evident. That maritime influence is even more immediately apparent to anyone arriving from another town across the Bosporus on one of the 20 ships in the fleet of ferry operator IDO. IDO is the only ferry company that offers a high-speed ferry service from Istanbul over the straits between Europe and Asia Minor. In 2011, IDO

of Kayabası’s satisfaction with power units from Friedrichshafen is shown by the fact that IDO has a total of 62 MTU engines in use. Almost all of their ferries are equipped with MTU propulsion and gendrive engines. The second biggest car ferry is powered by MTU Series 1163 engines, while Series 183 and 396 units can be found in the engine rooms of the smaller ferries. “The engines always deliver what our captains ask of them,” Kayabası enthuses.

Not only ferry passengers, but anyone traveling into the city center by car or underground will also encounter the MTU name. The famous city landmark, the Galata floating bridge, has a Series 183 engine to drive its emergency power genera-tor. And in the underground station in the bust-ling and trendy district of Taksim another MTU engine makes sure the lights never go out.

Gensets assure luxury lifestyleBut the public transport systems aren’t the only places where you will come across MTU en-gines and MTU Onsite Energy plants on a tour of the city. If you are lucky enough to be staying at the five-star Divan Hotel close to the Taksim transport interchange and Istanbul’s most famous

shopping and entertainment street, you can be equally assured that you will be able to enjoy the numerous facilities of this stylish accommodation without the disruption and inconvenience of power outages, thanks to the two 16V 4000 gen- sets sited on the hotel grounds that provide 2,145 kilovolt-amperes of electrical energy. “This is the first time we have worked with MTU Tur-key and I amdelighted that we have choosen this brand” relates Resat Dalay, Director of Enginee-ring at the Divan Istanbul Hotel. “For us, uninter-rupted hotel service is indispensable. We can always rely on the generators doing their job if there are power cuts on the mains grid.”

Seven months ago, the hotel was reopened after being completely renovated. Since then, the gensets have already been in use for near-ly 70 hours, sometimes for only a few seconds, on other occasions up to three and a half hours long. “We have had no problems whatsoever with

these units. I would always be in favor of using them again for a project of this type,” Dalay af-firms. Inside this spacious and extensive luxury hotel, it is obvious to the observer that the gen-sets have plenty to do if the power goes down. There are more than 200 rooms and 33,000 square meters of hotel floor space including health spa, restaurant suite and expansive lob-by to be supplied with energy. To be on the safe side, the gensets are dimensioned for more out-put than the hotel requires at present. Having two of them also makes maintenance easier. While one is shut down, the other remains on standby and can supply a large proportion of the electricity demand. And so that hotel guests can enjoy a Turkish coffee in the lobby – here the national drink is served stylishly on a silver sau-cer with a small Turkish biscuit – or hold their conferences without the intrusion of noise, the gensets are housed in a purpose-designed soundproof container.

backup for online servicesIf you need a functioning phone, TV and internet network on your city break or for your business conference, another MTU Onsite Energy client, Türk Telekom, is responsible for providing it. Those wishing to visit the emergency backup gensets at the Istanbul head offices on their tour of the MTU sights need to be prepared for a trip five me-ters below ground rather than a walk around the grounds as at the Divan Hotel. These gensets are housed in a specially excav ated subterranean ge-nerator room. In July 2011, the previous generators were replaced by three 16V 4000 modules. Instal-lation had been preceded by a demand analysis of the Turkish communications network. “With these more powerful units we have equipped ourselves for future energy requirements,” explains Ali Aydın, Chief Energy Manager at Türk Telekom. As a com-plete systems provider, MTU Turkey fully fitted out the 144-square-meter room with everything from the gensets to the control cabinets and electrical installations. Aydin has complete trust in the MTU Onsite Energy emergency backup units: “To date they have been in operation for 22 hours without any problems whatsoever.” One of the things he especially likes is that he gets a text message as soon as a power failure happens and the gensets spring into action. In the hard-fought private tele-communications sector, the uninterrupted service offered by Türk Telekom is especially important. “I can quite definitely recommend these gensets and the speedy and thorough handling of the project. We have also ordered MTU Onsite Energy diesel gensets for our site in Erzurum, this time with Series 2000 engines,” the manager adds.

The generator units run synchronously so one can act as backup for the other. If a power cut occurs just when you are standing in the generator room, you can experience what they do at first hand. Having suddenly been plunged into darkness due to the power failure, the generators are up and running – and the lights back on again – inside nine seconds. This Türk Telekom site requires around 800 kilovolt-amperes of electricity an hour. It handles 33 percent of the internet traffic vol-ume in Turkey. It is Türk Telekom’s third largest facility in the country. In total, Türk Telekom has roughly 5,000 individual sites which the company is gradually adapting to the ever more widely used telecommunications infrastructure by installing more powerful backup generators. After all, not only private individuals are using the phone net-work, GSM services, web TV and internet much more frequently. Banks, the police, the education ministry and other security services are also con-nected up. Unthinkable what loss of system data would mean to such Turk Telekom customers.

MTU Turkey and its market position

There has been an MTU service workshop for spare parts installation, maintenance and complete overhaul of MTU engines in Turkey since 1985. In the past year, the staff there overhauled more than 200 engines, including some custom-tailored units. The majority of them were marine and tank engines used by the Turkish Armed Forces. In 2002, the company moved to a new building providing office space, test benches and workshops in the Hadimköy district of Istanbul. Cylinder liners for the MTU Series 4000 engines have been made here since 2009. Since its entry into the Onsite Energy market one and a half years ago, MTU Turkey has become an important player in the market. The brand is positioned as a system supplier of tailor-made solutions and has built up a solid base in the continuous power segment for gas engines.

Constant energy supply a life-saverA power failure at a hospital such as the recently constructed Emsey Hospital opened in April 2012 could be life-threatening. The way to the hospital leads across one of the bridges to the Asian side of Istanbul. It has 31,000 square meters of floor space, is ultra-modern, elegantly furnished, fitted out with the latest equipment and, in particular, the most advanced communication standards. Physicians in Intensive Care Unites can view entire medical histories any time on-screen at the touch of a button. Furthermore, during opera-tions, specialists are able to share information regarding the surgery via a videoconferencing link. In addition, all necessary materials such as bandages or medications are issued exclusively using a barcode system. Patients throughout the hospital have access to an emergency button system which can be used to call a doctor for assistance not only from the wards but also from corridors. The quantity of technical refinements available in modern-day hospital care is astoun-ding – and will undoubtedly make patients at the Emsey Hospital feel they are in good hands. In order to systematically monitor all of those func-tions, there are 6,700 automated checkpoints. There are also 320 safety cameras in use, to monitor patients patients in all unites. They have to be in working order all the time, as does the sophisticated alarm system. “In a hospital the is no room for power failures. But in this region the mains grid is not so reliable. So, because of its highly sophisticated technology, we made the decision to have an emergency backup system with three Series 2000 diesel-driven generators from MTU Onsite Energy,” recounts Technical Manager, Erdal Aydın.

The hospital comprises roughly 200 well-appoin-ted rooms spread over four storeys and divided into five categories from single room to king suite decorated in bright yellow and opulently furnished with plaster moldings. It has nine opera-ting rooms on a dedicated floor and 55 examina- tion rooms for specializations of all types inclu-ding dentistry. Roughly 70 doctors will work here. Emsey Hospital is also assertive on having inter-national patients from other countries; based on their capabilities and close location to Sabiha Gokçen International Airport. As well as the emer-gency backup gensets, the hospital also has one Series 4000 gas engines supplied by MTU Onsite Energy that drive continuous duty generators. The Emsey Hospital needs 30,000 kilowatts of electri-city every day. If you want to see its silver-painted generator units, you need to take a walk through the grounds again, as at the Divan Hotel. There they stand next to the diesel gensets inside their own soundproofed building, so the patients are blissfully unaware if the backup generators have to be called upon to supply their full capacity and ensure smooth operation of the hospital despite a power grid failure.

Multiple energy supply backupThe electricity for the hospital is supplied via two separate cables – an initial safeguard in case one of the cables fails. As a second insurance policy, the 1,100-kilowatt diesel gensets are permanent-ly on standby and can be started up inside seven seconds to ensure the supply of life-sustaining electricity is maintained. Within twelve seconds, all three of the diesel power-backup gensets are running in parallel. If only two of them are re-quired to supply the present demand, one of them is automatically shut down again – a big plus in terms of energy-efficiency. The first seven seconds after a power outage are covered by a UPS. The emergency backup gensets have been in place since November last year and were com-prehensively tested in January this year. “So far they have already been in action for ten hours following grid outages, and they have always responded,” Aydin summarizes.

These are only some of the tracks left behind by the engines and gensets supplied by MTU and MTU Onsite Energy on the banks of the

Bosporus. More are added almost on a weekly basis. For example, IKEA Istanbul has emergen-cy backup generators supplied by MTU Turkey, as do Akbank’s gigantic office tower, the Mercedes-Benz bus factory and textile producer Özdo-ku Acıbadem Hospitals. So those seeking out the MTU energy sights in Istanbul should always make sure they have the most up-to-date guide.
