INTO THE GREEN ZONE Advancing the maritime energy transition for cleaner shipping
“What rubbish?” asks one of my favorite stories in this
edition of MAN Magazine. It shows how ditched food does not have to go to waste, but can be turned into clean electrical energy. Statistics show massive potential for this approach: According to the environmental organization WWF, in Germany alone the incredible amount of 300 kg of food ends up as refuse – per second. This equals 18.4 million metric tons per year. Maybe we all should look into our waste bins in the light of climate protection, for a change. Another great story and heartfelt matter of mine also
addresses climate change: For several years now, I have been advocating a “turn to gas” in maritime transport technology. The reasons are simple: Burning gas instead of heavy fuel oil reduces harmful emissions by up to 95%. It marks the beginning of a maritime energy transition and an era of green shipping. Together with pioneering ship owner Wessels, we walk the talk and retrofit the container ship Wes Amelie to LNG. Here’s a world premiere the environment will applaud. Finally, the hybrid power plant Borges Blanques in Spain shows how renewable energies can provide electricity 24/7 when integrated smartly. This nicely underlines an insight by Audi Lucas, Chief Digital Officer here at MAN, in this issue’s “Dialogue & Opinion” section: “Today, innovation occurs through collaboration, and the creation of a particular type of culture that is not afraid to experiment.” My reading of this: Instead of solemnly trying to reinvent the wheel, we need to work to tackle

An approach that is welcomed by the 37 participants currently undergoing turnkey training specifically developed by MAN Diesel & Turbo for the state-owned Société de Patrimoine du Gabon. “Our customer’s wish is to increase the expertise of its personnel for operations and maintenance of its power plant,” emphasizes Jérôme Louis, Head of Project Sales and Execution at MAN PrimeServ in France. The program’s purpose, therefore, is to enable future personnel to take over duties at the Cap Lopez power plant near Port-Gentil, Gabon’s second-largest city. This supports national self-sufficiency projects, in terms of both generating electricity as well as tapping energy sources. Along with the Alénakiri power plant in Libreville, also equipped and commissioned by MAN Diesel & Turbo, the Cap Lopez power plant will supply a substantial 20% of the 600 MW installed in Gabon.

The Cap Lopez power plant has three 18V51/60 dual-fuel engines manufactured in Saint-Nazaire and running primarily on natural gas. “We have set up and adapted our training program with those units in mind,” explains the project manager. The availability of a natural-gas-fueled test bench in the assembly hall of MAN at Saint-Nazaire allows for hands-on training on genuine equipment. A crucial point, considering

plant operations and maintenance, from basic engine maintenance to operating the facility, are performed properly. As a result, training is geared toward future instrumentation and control supervisors, mechanical foremen or shift leaders. “Comprehensive and qualified training of the people operating a plant is absolutely essential,” agrees Wayne Jones. That is why next to theoretical classes and practical exercises at the Academies – which offer a risk-free environment to acquire maintenance and troubleshooting techniques – the Academies further offer on-site training in real-life operations.

to support customers with regard to plant operations, ranging from full operation and maintenance to remote monitoring services of the plant’s performance. The qualification of local staff is one more component of this portfolio. And who is better equipped to pass on expert knowledge than the original manufacturer? “We constantly strive to keep customers up to date with cutting-edge technology. In order to do so, we continuously develop our own employees to ensure they can provide the level of service our customers both expect and deserve,” says Wayne Jones. This also includes further developing trainings and courses. The MAN PrimeServ Academy in Saint-Nazaire, for example, has acquired a unique level of experience in regard PHOTOS: Afric Telegraph, JF Couty
to power plant operations. Inspired by and adapted from a model initially created for the customer EdF (Électricité de France), the Academy is currently standardizing the training given to the Société de Patrimoine interns so that it can be provided at other facilities. “We are pursuing a comprehensive solution approach. Our turnkey training programs, for example, are being more and more integrated into our company’s products and services,” says Jérôme Louis.
Each branch has its specific needs. What are your customers from the Turbo business asking for? Customers of the Turbo division generally prefer a mix of hands-on training and professional classroom lectures with a direct link to job-specific activities. When it comes to training content, topics related to safety, efficiency and availability are most important. Furthermore, customers expect trainings oriented toward the job roles of the personnel handling our equipment. So our training portfolio focuses on operators, mechanics, and instrumentation and controls engineers. The training venue is nowadays often on site. Additionally, some customers invest to send their employees to our Academies, making use of our in-house trainings that contain more practical lessons. How are these branch-specific trainings structured? Generally speaking, we are always aiming at a good balance between providing information and applying it in order to build up knowledge sustainably. With regard to training content, we normally start from the big picture, then go down to technical details and finally troubleshooting activities. Maintaining enthusiasm for learning, fostering interaction and a diversity of methods make it even more successful. During an on-site training we have courses in front of customer’s equipment and in the control room, although we can’t interrupt ongoing operations. We use exercise sheets, stickers, drawings, pictures or case studies in order to make these lessons more valuable for everyone. Trainings in our Academies can focus more on hands-on activities. In Oberhausen and Zurich, we can make use of training machines and a variety of models and simulators Can you reproduce all situations at the Academies? Due to the sheer diversity of machines and systems, there will always be differences between our training objects and the customers’ equipment. But from our customers’ point of view it is not necessary to be trained on all specific details, such as the complete assembly of a machine. Turbomachines are complex and designed to run steadily. So it simply does not happen often enough that such knowledge is needed and applied. So during our mechanical trainings, for example, we rather need to focus on enabling our customers to organize, prepare and support repair activities. Trainings also concentrate on routine maintenance, as well as evaluation of the condition of machines, essential parts and systems. To train operators and I&C engineers, we are about to extend with sophisticated process simulations. Such training media will help to train on site and in-house very efficiently. We can simulate almost any situation, and show features and settings of the control system. This will bring training another big step forward. 07
A CATALYST FOR CLEAN MARITIME TRAFFIC
Progress toward a reduction in the environmental impact of maritime transport has been somewhat slow and geographically uneven. But the call for transition is becoming louder and has the shipping industry looking for eco-friendly solutions. Since 2016, the Tier III strict emission limits for NOx have been in effect. These regulations, from the UN’s International Maritime Organization (IMO), aim to reduce NOx emissions by 70%. The restrictions apply to vessels in North America, the US Caribbean, the Baltic Sea, the North Sea, and all future NO x Emission Control Areas. Any ship that might pass through these zones must comply with the regulations, which basically means all vessels with keel laid after 1 January 2016. “While previous standards could easily be achieved by turning off the engines, Tier III calls for such a drastic reduction in NO x emissions that it can only be achieved using technologies such as SCR, selective catalytic reduction,” explains Dr. Gunnar Stiesch, Head of Engineering Engines at MAN Diesel & Turbo. SCR units inject a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. This diesel exhaust fluid, as it is commonly known, reacts with NOx, converting pollutants into natural elements. The drawback: Most units are big and heavy, taking up valuable space and weight in engine rooms. A problem for which MAN Diesel & Turbo, together with partner Mitsui Engineering & Shipbuilding, presented a solution. “Thanks to our many years of experience in developing SCR systems, we were able to reduce the overall size, while still maintaining the effectiveness of a much larger design,” says Stiesch. “This opens up new options for our customers to comply with tightening environmental standards. And we are proud to contribute to a more sustainable future of shipping and global trade.”

Past dramatic mountains and peaks, deserted beaches and untouched lands, the MS Lofoten cruises just as it has done for more than 50 years. Named after the breathtaking archipelago in which it mainly operates, the ship may be the oldest in the famous Hurtigruten fleet, but it still reliably transports freight and passengers along the coast of Norway.
Below deck, the main engine – a seven-cylinder, two-stroke Burmeister & Wain DM742 VT2 BF90 – works away with an output of 2,447 kW (3,325 horsepower) and a top speed of some 17.7 knots. As it’s the original engine, it has propelled the ship over more than 7.4 million kilometers, running up well over 300,000 working hours. The idea was floated to replace the old B&W in the ’90s, but was soon discarded because of its continued, excellent performance and, crucially, MAN Diesel & Turbo’s ability to continue delivering spare parts. In 2010 the engine underwent a significant rebuild, and MAN PrimeServ regularly assists in maintaining the now almost historical engine. Which is only fitting, as in 2000 the MS Lofoten became the largest ship ever deemed worthy of preservation by Riksantikvaren, the Norwegian Directorate for Cultural Heritage Management – a special engine aboard a very special ship. ▼ Still powered by the original engine, thanks to the parts, support and services of MAN.
▶ A pivotal role model: The “Wes Amelie” is the first container ship to be retrofitted to LNG.
A ROAD MAP TO THE GREEN ZONE
For the shipping industry to be carbon-neutral by 2050, all stakeholders need to support the maritime energy transition. The story behind the world’s first container ship to be converted to LNG offers insights into the challenges faced, opportunities offered and pioneering drive required.
The Baltic Sea is one of the most heavily trafficked regions in the world, accounting for up to 15% of the world’s cargo
transportation. It’s also one of the most heavily regulated shipping zones and is turning into a model for green mari-
time transport. Surrounded by nine countries – Sweden and Finland to the north, Russia, Estonia, Latvia and Lithu-
ania to the east, with Poland to the south, and Germany and Denmark to the west – the region serves as an environmental benchmark for the shipping industry, which has only been achieved by collaborating and adopting more than the

minimum international standards. Instead of kicking the can down the road, the region has signed up to a cleaner
road map for the future of shipping. And it’s a road map
that MAN Diesel & Turbo is also committed to advancing.
This commitment was recently demonstrated by the company’s pivotal role in engineering the world’s first conversion of a container ship’s propulsion system from heavy fuel oil to low-emission LNG: the Wes Amelie.
IDEAL CONDITIONS AND MOTIVATION
Launched in 2011, the Wes Amelie is a modern 1,000-
TEU carrier, optimized for 45-foot containers, that operates in the North and Baltic Seas. Owned by the German shipping company Wessels Reederei, the vessel will be retrofitted to dual-fuel operation. The motivation for the retrofit came from a number of directions. The first reason was regulatory, as Christian Hoepfner, General Manager and Head of Business Development & Special Projects at Wessels, outlines: “The design, construction and high ice-class parameters of the Wes Amelie meant that it is predestined for the shipping routes spanning the highly regulated North and Baltic Seas,” he explains. “As they are both within Emission Control Areas, the ships need to meet the highest environmental standards and strictest limits for emissions. By converting to a low-emission fuel, we are safeguarding the future of this container ship as well as our own competitiveness in this market.” Once it was announced that regulations would be tightened in the North Sea and Baltic Sea Sulphur Emission Control Areas (SECAs), Wessels started investigating how to maintain, and increase, the competitiveness of their container ships for charterers in this zone. Here, after 2015, all ships have to reduce emissions of sulfur oxides (SOx) from 1% down to 0.1%, and would have to eventually also reduce nitrogen oxides (N0x). What they found out: Running on LNG, the Wes Amelie would drastically reduce emissions of SO x by over 99%, NOx by approximately 90%, and CO2 by up to 20%, without the need for aftertreatment. The numbers were convincing.
THE ENVIRONMENT AND EXPERTISE
The second reason for adopting LNG was more of a
personal motivation to protect the environment. Basically, the choice came down to continuing with marine diesel oil with the addition of a scrubber for exhaust gas cleaning, or
A global focus
Dr. Uwe Lauber , CEO, MAN Diesel & Turbo, is convinced that the only way forward is through global policies.
“A container ship transports huge quantities of goods over thousands of sea miles with a single engine. Compared with the emission levels of private transportation, they are almost negligible. In absolute terms, however, the scale of the maritime industry means that its global emissions remain too high. If we are serious about decarbonization, we need rules that apply to everyone. If we want the shipping industry to be carbon-neutral by 2050, then we have to take action today. Only when there is a clear regulatory framework, will we all know what needs to be done. This can all be steered by policies.”
switching to LNG. The former was rejected, as an open-loop system would result in discharging waste water containing sulfur into the sea. So, the decision went with LNG, as Christian Hoepfner explains: “A scrubber would have been simply inconsistent with our desire for an eco-friendly operation.” The third reason was based on engineering expertise. A retrofit on this scale is not a trivial matter and requires specialist know-how, parts and implementation. The Wes Amelie was originally fitted with an MAN 8L48/60B diesel engine, one that MAN Diesel & Turbo had considerable experience in converting to the dual-fuel operation. Which meant MAN was the preferred partner for the task. By scheduling the retrofit during a major planned engine

may limit levels of sulfur, particulate matter and/or nitrogen oxides. In addition, from 2020, the global marine sulfur emission limits will be cut from 3.5% to 0.5%.
AFTER THE RETROFIT, THE ENGINE consumes about 4,400 m3 of natural gas per hour and has an average output of 7,800 kW.

shipping industry is global by nature, and at the end of the day, it requires regulation on a global scale. The International Maritime Organization has to ensure a level playing field,” adds Lauber. However, this does not mean that local governments should be idle: “We need a ‘new deal’ to drive this initiative, which unites ship owners, ports, shipyards, engine manufacturers, as well as politics,” explains Lauber. “All the ingredients necessary to establish LNG are there, but it is politics that need to lead the way and make the whole industry believe that this is really happening.” This is a lesson that Wessels has had to learn the hard way, too. When the cost estimates for the conversion came in, the project almost didn’t get off the ground. From a mere economic standpoint, the case for the retrofit was a tough one to argue. The solution would require an element of political commitment, too. It was the pioneering but fully replicable character of the project that convinced the German government to get involved.
THE MULTIPLIER EFFECT
The Wes Amelie has 23 sister ships, and 16 of them are structurally identical, which guarantees that similar projects could be easily implemented in the future. In addition, as a total of 82 type MAN 48/60 engines have been installed in ships of various kinds, the actual potential for retrofitting such vessels to LNG is even greater. The scalability of the engineering services and the development costs would significantly reduce the costs for all follow-up projects. This clear multiplier effect was the deciding factor in securing additional financial support for the project from the German government via its Federal Ministry of Transport and Digital Infrastructure (Bundesministerium für Verkehr und digitale Infrastruktur – BMVI). Once the BMVI recognized the contribution such a project could make to the industry in the long term, additional funding was awarded. This would also enable a short, three-year amortization of the investment. Hoepfner is convinced that it was this interplay of political support, tough regulations, advanced engineering and the right attitude to environmental protection that sealed the eco-friendly deal for the ret-
The ideal solution
Christian Hoepfner, General Manager, Wessels, argues for a fairer levy to support the transition to greener fuel.
“The actual retrofit, and its financing, is only one side of the story. We need an LNG infrastructure in place providing easy access to LNG as bunker, and LNG has to be cheaper than the usual petrofuels in usage. The transition to LNG as fuel is not easy sledding, and at this early stage the ship operator or charterer expects benefits in using LNG-fueled ships. It’s unacceptable that the shipping companies or the individual ships have to foot the bill alone to protect the environment. In an ideal scenario, each transported container has to pay a SOx, NOx or CO2 levy, and this levy will be explicitly used to support green shipping initiatives.”

transition,” agrees Dr. Thomas Spindler, Head of Upgrades & Retrofits – MAN PrimeServ Four-Stroke – MAN Diesel & Turbo. “But as the example with Wes Amelie confirms, it needs a broad commitment to make it fly. Next to advanced engineering and personal conviction, pushing through with this will take better regulation and the political will to succeed. And we will keep pushing on all levels,” he promises.

â–˛ Investing in the power grid of eastern Indonesia, the government aims to increase the share of the population with access to electricity from 85% to 98% by 2022.
INDONESIA HAS A PLAN

Southeast Asia is currently one of the most active markets in the world. One of the main drivers: Indonesia. Having quickly recovered from the Asian financial crisis, the country is now the largest economy in the area, growing at an annual rate of roughly 5%. The stable growth is not without consequences: A report by Transparency Market Research indicates that Indonesia’s electricity demands will more than double, to 442.5 terawatt hours (TWh), by 2022. To meet this demand, the government under president Joko Widodo launched an ambitious program in 2014 of adding 35 GW of new installed capacity by 2019. An ambitious target, considering that the state of Indonesia consists of over 13,000 islands, of which around 900 are permanently inhabited. “Owing to the geographical structure – Indonesia is the largest island state in the world – small and isolated electricity grids are required. Given our wide-ranging experience of decentralized power plants, this is of course a good opportunity to expand our business,” explains Massimo Casal, Country Sales Manager Power Plants for MAN Diesel & Turbo. Casal estimates a potential for the company of 2 to 2.5 GW, primarily in dual-fuel power plants. Most of the new power plants are to be established in eastern Indonesia, a mostly rural region that still regularly suffers from brownouts and mainly accounts for Indonesia’s porous electrification factor of 91%. While the government aims to push gas-powered plants for environmental and economic reasons, the pipeline system necessary is not yet in place everywhere. “As the development of the domestic gas infrastructure will take longer than the establishment of new power plants, dual-fuel solutions that can switch from diesel to gas as soon as it is available are the best solution,” says Casal. 21

needs. Following this, 12% of Costa Rica’s energy needs were met by geothermal power, while wind accounted for 10%.

Though Carlos Manuel Obregón, president of the Costa Rican Institute of Electricity (ICE), stated that the institute expects renewable power generation to stay “stable” throughout 2017, climate change and resulting unstable weather conditions give rise to concerns. The El Niño phenomenon strongly affected 2015, while 2016 had low rainfall throughout the country during most of the year. The high renewable-energy percentages could only be maintained through optimization of the medium and large storage reservoirs of the ICE. Climate change studies are further projecting changes in precipitation patterns, temperature and water availability in Central America, which could significantly impact the hydroelectric power sector.
EXCHANGING A MUCH-NEEDED COLOSSUS
Essentially, depending on renewable energy also means being susceptible to volatile weather conditions. And while Costa Rica is investing in further renewable energy plants to ensure a more stable output, the country still depends on fossil-fuel plants. The largest of these in operation is the ICE Garabito thermal power generation plant, located in Montes de Oro, in the Pacific province of Puntarenas. Equipped with 11 MAN 18V48/60 engines operating with bunker fuel, Garabito has a generating capacity of 200 MW – enough to provide power to 80,000 homes. While the rains of the wet season supply enough water to power the numerous hydroelectric plants, summer often means periods of drought and a depletion of water reservoirs. In which case Garabito supplies the much-needed additional power to the grid. With the Garabito power plant, the population of Costa Rica can be prepared to face any kind of shortages caused by climate change, or failures in renewable energy units. “So

▲ Hand in hand: MAN employees from three different countries working on detaching the turbocharger from the old engine for reuse on the new one.
The Garabito power plant is the largest fossil-fuel power plant in Costa Rica. To meet with the country’s emissions limits and those of the World Bank, the plant is equipped with exhaust gas treatment systems and relies on the intrinsically clean combustion of the advanced 48/60 four-stroke engines, followed by an electrostatic precipitator.

the plant serves as an insurance policy”, explains Verny Rojas Vásquez, Garabito Plant Manager. When one engine had issues in 2016, it was a problem that needed to be solved fast. “We immediately called MAN for support; a day later they sent someone from MAN Diesel & Turbo in Guatemala. And a week later they sent specialists from Augsburg for an in-depth analysis,” explains Rojas. When it was apparent that the engine had to be exchanged, Garabito commissioned MAN Diesel & Turbo for a new base engine. After construction, the 145-metric-ton engine was sent from the production site in Augsburg to Costa Rica via a circuitous route, covering a linear distance of 9,580 kilometers. The engine was transported on a heavy transport vehicle to Heilbronn, from there on a barge to Rotterdam, where it traveled on board the freighter BBC Nile to Puerto Caldera in Costa Rica. There a barge took the engine to a specifically built landing stage on the other side of Puntarenas.
SECURING AN ESSENTIAL PART OF THE POWER MIX
“The logistics of it all was complicated, because sea transport does not always run exactly to schedule,” says Sebastian Herreiner, Superintendent Engineer at MAN Diesel & Turbo. “But we worked with a long-standing partner and it all went smoothly,” adds his colleague, Rene Zimmer, Section Manager. The last 15 kilometers, between the harbor and the power plant, the new engine traveled on mostly unpaved roads. “It was a bit nerve-racking when we had to go through the sugar cane fields,” remembers Herreiner. “It was raining hard and the ground was slippery. On top of that we had to cross a number of small streams with our heavy load. Luckily it all went well, though.” On arrival at its final destination everything was prepared so that work could start immediately. “Together with the heavy-lifting company we had brought out the old engine, taken it apart and overhauled the parts that could still be used,” explains Klaus-Jürgen Nertinger, Superintendent Engineer with MAN Diesel & Turbo. His mixed team from MAN Diesel & Turbo in Germany, Panama and Guatemala was responsible for the reassembly and the subsequent installation of the new engine. “The customer, ICE, was extremely supportive each step of the way, which made our work a lot easier,” says Zimmer. By mid-December the work was completed. “MAN Diesel & Turbo worked efficiently and finished in excellent time,” states Rojas, “It was extremely important to us that the work be done before the start of summer bePHOTOS: chrisorama.com

A NEW STANDARD
It may not be much to look at, but a new guide vane segment is revolutionizing production at MAN Diesel & Turbo. It is the first complex 3-D-printed part to be used in serial production of gas turbines. In April 2017, it was integrated into a gas turbine for real operation by a customer – taking 3-D printing far beyond the testing phase. This milestone is a result of a decade of research and development and puts MAN Diesel & Turbo in the unique position of being the first manufacturer in the world to use complex 3-D-printed components as a standard in serial production of gas turbines. 3-D printing – or additive manufacturing – is still mainly limited to prototyping in many industrial branches. The potential of additive manufacturing touches many steps in a product’s genesis, however, offering numerous advantages along the entire value chain. Next to shortened development cycles, 3-D printing enables, for example, a more complex component design, accelerated production and shorter delivery times. Further, it could potentially change the nature of spareparts services. Warehousing, tracking and distribution of spare parts is costly, while 3-D-printed parts can be produced right on call. “The digital data from our R&D departments can be converted into better products more quickly than before, while customers are supported throughout the entire product life cycle with 3-D-printing-based services,” explains CEO Uwe Lauber. To further tap into the potential the technology offers, MAN Diesel & Turbo is currently investing in the establishment of the “MAN Center for Additive Manufacturing.” The center will combine the expertise of design specialists, materials engineers and manufacturing engineers to develop and realize the opportunities for 3-D printing for all of MAN Diesel & Turbo’s business units.
ARRIVAL OF A GIANT 34

The biggest axial compressor worldwide has finally reached its final destination: South Africa. In terms of efficiency, size and cost, it is a game changer in the global air separation market.
A All eyes to the sky. All the people watching are holding their breath. Above, in the blue South African skies, a gray giant is dangling in the air. The AR-140 is the biggest version of
the MAX1 generation of axial compressors – the biggest of
its kind worldwide. After an epic journey from MAN’s pro-
duction site in Germany to Secunda, South Africa, it is now
on its final stretch. A massive, specialized crawler crane has been brought onto the site to lift the 240-metric-ton
piece of cutting-edge technology to its final position. It’s a day in history for Christo du Plooy, Sales Manager at
5,000 TONS of oxygen per day: The AR-140 compressor is at the heart of the largest air separation unit ever built.
MAN Diesel & Turbo South Africa: “This first-time installation of the compressor is a critical and important milestone
for us as a company. It is a big achievement and a great honor for us to be involved in this project.”
The compressor is at the heart of the largest air sepa-
ration unit (ASU) ever built, with a total capacity of 5,000 metric tons of oxygen per day. That’s a major improvement
from present production capacities of roughly 3,500 metric
tons. It is being constructed on SASOL’s synthetic fuels and
chemicals complex in Secunda, but is owned and operated
by Air Liquide. The new ASU will enable the company to supply large quantities of industrial gases to the manufac-
turing processes on site. Without a doubt, this day marks a milestone for Air Liquide, too. Amine Houssaim, Director for Southern Africa with Air Liquide Large Industries, has
made space in his schedule and driven 130 km from Johannesburg to witness this special event. “We are convinced
that the AIRMAX1 is the compressor that will provide us with the best fit for our design. We have already been coop-
erating with MAN in South Africa. So far the cooperation is very good at each level of the organization. And we are very excited to see this equipment being lifted today.”
TEAMWORK AND PRECISION
Slowly, the compressor is being moved toward the
massive, 11-meter-high concrete platform. The AIRMAX
consists of the main AR140 compressor and a type RG 71-4 booster compressor, driven by an electric motor, also one of
a kind, which was lifted onto the platform a few days before.
Three huge pipes are sticking out of the gray protective cov-
er. They will be joined to other pipes already erected around the platform, sucking in and compressing the air from

the atmosphere with an effective volume flow rate of over 1 million cubic meters of air per hour. The air then goes through a cooling unit underneath the platform, as well as a purification cycle. It then enters the cold box for cryogenic distillation, where the air is separated into its main constituents oxygen, nitrogen and argon. On the ground, workers dressed in full security gear are holding on tightly to ropes fastened to the compressor, in case the wind picks up. In the vertiginous heights of the platform, Dennis Müller, German Field Service Engineer, wearing a harness and safety ropes like an alpinist, is directing the crane operator toward the right position. “This is precision work,” Müller points out. He has been deployed in South Africa since October and will later calibrate the compressor, thrilled about his exciting task. “Working with the entire team on site has been great. Every one of us has been anticipating this moment eagerly for the last months.”

Office staff as well as construction workers have
stopped their daily routine to take a glance on site, watching the progress from a safe distance. The air of excitement is tangible, despite the fact that some have been working on massive projects for decades, like Stehan van der Post, Project Director for Air Liquide. “The construction of the concrete structure supporting the compressor has been a challenge. A lot of rebar was required, which made the pouring of the concrete technically difficult. The 11-meter-high columns were done in a single pour. That makes this lift special. There is a sense of accomplishment for the team. It is something tangible that demonstrates the fruits of our labor.” But the excitement has not been restricted just to the site, Tamzin Womarans adds with a smile.

awareness and global needs to save energy and reduce the carbon footprint, at the same time providing solutions for a growing population. The AIRMAX addresses all these challenges. It is the most compact concept in the market, yet still the most efficient one. Two trains of large air separation units can now be replaced by a single one, and for the standard pressures there is only one intercooler needed. The design of the new axial blading and the subsequent radial diffuser have been optimized with methods used in the aircraft engine industry. All components have been optimized for efficiency, the lowest possible power consumption and superior performance. “The sheer efficiency and the technology that we are implementing here is probably a few decades more mature than existing technology,” du Plooy emphasizes.
A COST-EFFECTIVE WAY TOWARD THE FUTURE
Certainly this is also in the interests of the customer,
Air Liquide. Replacing two trains with one results in significant cost savings. The efforts for site construction, operations and maintenance are also lower due to the compact, modular design. “We obviously benefit from economy of scale,” says Amine Houssaim. “We are very happy that today MAN has a solution that can accommodate this size as well as the efficiency that we are targeting.” South Africa has been facing serious energy constraints for a number of years, with energy costs increasing. More efficiency is also needed to reach climate-change goals. Like other companies, Air Liquide is engaged in optimizing the efficiency of its operations, thus reducing the energy footprint. An engagement that is certainly not limited to the air separation industry, as another recent project shows. In spring 2017, MAX1 technology convinced the first customer outside this branch, coming into play here for the production of steel. This strongly underlines the fact that efficiency is key throughout the industries worldwide. Slowly the compressor is being lowered onto the platform. Everything goes perfectly well. “We are on track in terms of planning and very eager to see this plant comvolved with this flagship project since the inception just

MASTERS OF PRECISION
◀ Several hundred production specialists, like Abdullah Onur, work at MAN Diesel & Turbo’s site in Oberhausen. ▶ The large Carl Zeiss coordinate-measuring machine ensures the quality of high-end screw compressors.
At the turbomachinery production site in Oberhausen, a skilled workforce makes every micrometer count.
Meters-high machines are closely spaced as far as the eye can see in the huge MAN Diesel & Turbo production site in Oberhausen. The sound of metal being worked permeates the space where several hundred production specialists are at work. At its turbomachinery works in Oberhausen, Ger Germany, MAN Diesel & Turbo develops and manufactures compressors, turbines and complete machinery trains for the various needs of the industry worldwide. This includes in-house manufacturing of many com com-
ponents as well as their assembly to a finished machine or train. “We manufacture individually according to very spe specific customer needs, which means that we often have a batch size of just one,” explains Dr. Carsten Achtelik, Head of Production in Oberhausen. “And that we have only one shot to get it right.” Precision is, accordingly, key – and so is the workforce on this 70,000-square-meter site. Despite hundreds of special machines, it is experienced employees who render the last quantum of quality possible – for example, by choosing the ideal processing method. Where everything may depend on accuracy down to the micrometer, experience is invaluable. “We have to be able to guarantee our customers certain levels of efficiency and performance

for the machinery we manufacture, which is why have to work within very narrow tolerance ranges,” explains Achtelik. This is true of small components and also of large ones, such as the rotor of a 100 MW steam turbine. These may measure several meters in diameter and can weigh 20 or 30 metric tons. When they are in use at 5,000 rotations per
minute, precision needs to be up to a hundredth of a millimeter. And that for many years, as the final products, worth some million euros each, are in operation for decades. One of those experienced specialists is Wolfgang Rau. He has been working at the MAN site for 30 years. The CNC machinist is standing next to a digitally controlled chipping machine and attentively supervises how the machine slowly turns its program sequence into a high-precision contour of the metal. If a measured value does not match, Rau has to make a decision. “We manufacture so individually that serial production is possible only within very narrow limits,” explains Rau. And so the machine-driven execution is still strongly supported by the experience of the production workers. For example, inserting the blades onto a shaft, to finally create a rotor: Each blade is manufactured individually on a high-tech machine in the same production hall, some meters away. The insertion into a notch in the shaft takes up to five minutes each, depending on the blade size. Besides all high-tech processes here, this step is ▲ This close-up of a customized axial compressor shows its intricate detail. ▶ Thorough quality controls by the experts are added to every step of production.
executed by the workers by hand, converting their experience into quality. “This step, demanding flexibility and a high level of experience, could not be done by a machine,” says Abdullah Onur, who is one of the specialists for that task. “The requirements of that operation are so individual that it would be nonsensical to apply a robot here.” Clearances have to be checked, and occasionally adaptions to a row of blades have to be made. Once a blade is inserted, Onur and his colleagues immediately can tell whether they are sitting properly – to the hundredths of a millimeter. The turbomachinery coming out of Oberhausen has to perform for decades while withstanding immense stresses. A gas turbine blade, for example, is exposed to temperatures of more than 1,200°C, enduring pressures between 10 to 15 bar. Next to high-tech materials employed, it is this accuracy in production that guarantees MAN Diesel & Turbo’s customers longevity and efficiency of their turbomachinery. To training supervisor Thomas Wischermann, the human factor is crucial when working with the machines: “To know how the machine works, our experts have to have a profound knowledge of materials, for example. This is why apprentices in their first year also learn how to rasp by hand,
Dr. Carsten Achtelik, Head of Production with MAN Diesel & Turbo in Oberhausen
MAN Diesel & Turbo puts a strong emphasis on training their own personnel. Currently, 85 apprentices are working in the practice area. Even after completing their apprenticeship, it will take a few more years before they have gathered the necessary experience. “Having to work according to the ‘first time right’ principle puts a great emphasis on our production crew,” explains Carsten Achtelik. “It takes years to get the kind of experience to be able to confidently manufacture a part with the needed precision in just one go.” ▪

Audi, let’s try and get a better grip on that buzzword “digitalization.” What is it we are talking about when we use that word? I actually prefer to keep it simple and just say “digital.” I think the term might be a bit of a misnomer, and too often is perceived as “IT.” To me the actual meaning of “digital” is much deeper. What it really gets to is a new or changing way of thinking about businesses and business models. If we look at the world and the economy today, things are increasingly moving at an exponentially rapid pace. At the actual heart of “digital” is the ability to adapt your company and business model to that pace. Can you give an example? Take the development of the retail industry in the late ’90s, which saw a change moving from bricks-andmortar stores to things like online shopping. Traditional stores found themselves eroded and had to adapt to new business models and ways to interact with their customers. No doubt, it was the Internet that triggered and enabled that change. But those companies that succeeded were the ones that at a rather rapid pace were able to change the way they interacted with their customers. In the media industry this started even earlier – years before the first digital medium came up. It was the invention of the videocassette recorder, which for the first time enabled the end consumer to record, watch and distribute content independently of its air time. This changed the business and market model of a complete industry. A certain tech-

nology triggered it, which itself is already long gone today. But at the heart of the transformation that took place was a fundamentally changed relationship between an industry and its customers. The VCR was only the first shot, and over the next 20 years or so we could watch the production studios lose control over their product. But the VCR and cassettes were analog technology. How does that add up then? We should not get too hung up upon whether things are “digital” or “analog,” Betamax or

NEWS & FACTS
Advanced LNG system for Norway Two new ferries for ship owner
and ferry operator Torghatten Nord promise state-of-the-ar t per formance, comfort and reliability. Built by Vard Shipyard Group, designed by Multi-Maritime, and equipped with a fuel-gas supply system from MAN Cryo, MAN Diesel & Turbo’s marineLNG fuel-gas-system manufacturer, they are scheduled for delivery in 2018. “We are committed to delivering two excellently performing ferries, which is why we have chosen MAN Cryo as fuel-gas supplier,” says Thor Inge Skov, Purchase Manager at Vard Group AS, in Brevik, Norway. ▲ The LNG supply system for the double-ended RoPax ferries consists of a 175 m³ vacuuminsulated storage tank with auxiliary equipment.
Double the size of Los Angeles, and with an annual extraction capacity of 4.5 million metric tons, the Martabe Gold Mine on the Indonesian island of Sumatra is one of the world’s largest. To secure a stable energy supply to the mine, MAN Diesel & Turbo is to deliver and install four MAN 18V32/40 gensets for a power plant of the energy company PT Sumberdaya Sewatama. 46
▼ With four MAN four-stroke engines, the power plant will supply Martabe with up to 24 MW of power, eliminating acute bottlenecks.
▼ The new refinery will expand Nigeria’s capacity to meet its rising mobility needs.
Nigeria: toward fuel independence With an order volume in the tens of millions, MAN Diesel & Turbo will deliver two compressor trains to Nigeria’s Dangote Oil Refining Company, to be employed in the company’s refinery in the capital of Lagos. Each consists of an axial compressor driven by a steam turbine with about 30 MW of power. “This refinery will satisfy 100% of the fuel needs of Nigeria,” explains Alhaji Aliko Dangote, president and CEO of the Dangote Group. The new building should enable Nigeria, as Africa’s biggest crude-oil producer, to also raise its processing capacities, finally becoming more independent from imported fuels. Wayne Jones, MAN Diesel & Turbo’s Chief Sales Officer, sees it as a milestone: “This will have a huge impact on the economy of not only Nigeria but all west Africa. We are proud to be a part of this project and gladly offer our equipment and technological expertise to help make the Dangote refinery not only Africa’s biggest, but also one of the most efficient operations on the continent.”

is the range of ambient temperature an axial compressor by MAN Diesel & Turbo will have to cope with at a steel works in Luleå, Sweden. While the project marks another breakthrough for the company’s MAX 1 technology, this range of inlet temperatures is making great demands on air compression.
$18 BILLION The industrial gas turbine market volume will exceed this amount by 2024, the latest study by Global Market Insights, Inc., predicts. In 2015, the value was $16 billion. Stricter carbon emission regulation across the globe is one of the main drivers of this growth.
