2 MAN Diesel & Turbo The responsible way in leading technology MAN Diesel & Turbo is the world s leading designer and manufacturer of low and medium speed engines engines from MAN Diesel & Turbo cover an estimated 50% of the power needed for all world trade. We develop two-stroke and fourstroke engines, auxiliary engines, turbochargers and propulsion packages that are manufactured both within the MAN Diesel & Turbo Group and at our licencees. More than ever before, MAN Diesel & Turbo s development focus is the environmental performance of our engines. Using our unrivalled grasp of large engine technology, we aim to make our engines progressively cleaner, more powerful and more efficient. Our absolute commitment to reducing emissions while increasing fuel efficiency and power density starts with our active partnership in the emissions law making process and ends with the delivery of engines that achieve an ideal synthesis of prime mover characteristics.

3 The changing climate Time to act EEDI In a nutshell The IMO regulations Time to act New standards What is it? Climate change is a major challenge facing the world today. As a result of the greenhouse effect, caused by emissions of gases such as carbon dioxide (CO 2 ), average temperatures are climbing. This threatens fragile ecosystems and poses huge risks for agriculture potentially destabilising the global economy. In our own interests, and those of future generations, we all share a responsibility to minimise the impact of climate change. This means working proactively to reduce greenhouse gas emissions. Shipping makes a difference Although shipping is already the most efficient form of bulk transportation, it plays an important role: increa sing globalisation is set to raise the amount of goods travelling by sea. Against this background, the International Maritime Organisation (IMO) has identified potential for improving the efficiency of shipping even further, based on existing technologies such as streamlined engines and improved design. After intensive discussions with stakeholders, the IMO has adopted a number of mandatory instruments requiring new ships to meet higher standards of efficiency. These encompass every stage of a ship s lifecycle, applying to design, operation, maintenance, crew training, upgrades and retrofits. One of these measures is the Energy Efficiency Design Index (EEDI), which requires new ships to meet a certain level of energy efficiency from the outset. Another mandatory scheme, the Ship Energy Efficiency Manage ment lan (SEEM), which governs operations, applies to all ships. Financial incentives In addition, market-based measures such as levies or emissions trading may be introduced in the future, creating further incentives for efficient ships. These are currently the subject of discussion at the IMO, although they are proving to be controversial. The Energy Efficiency Design Index (EEDI) calculates a vessel s energy efficiency, based on a complex formula. This takes into account the ship s emissions, its capacity and speed. The lower a ship s EEDI, the more efficient it is. Under the regulations, ships are required to meet a minimum energy efficiency requirement in other words, their EEDI must be equivalent to or less than a threshold value. Who is affected? The EEDI does not apply to all ships. Initially, it targets the vessels responsible for the most emissions. In its current form, it applies to new ships of and above 400 GT, where a building contract is placed on or after 1 January If there is no contract, it applies when keel-laying occurs on or after 1 July In both cases, delivery must be on or after 1 July However, nation-states have the right to delay the EEDI s application by up to four years to ships flying their flag. Older vessels will only require an EEDI should they undergo a major conversion on or after 1 January CO 2 emission EEDI = = Benefit of ship Cf SFC Capacity speed New ships over 400GT Keel laying after July 2013 In addition, EEDI benchmarks will be raised succes Global CO 2 emission Shipping trade routes sively new ships built in 2015, 2020 and 2025 will need to meet even higher standards And who is exempt? Vessels with diesel-electric, gas turbine or hybrid propulsion do not need an EEDI. Currently, RoRo, Roax, cruise, offshore and other vessels not explicitly mentioned in the regulations are also exempt. However, the IMO has announced its intention of expanding the EEDI to include additional types of ships down the track, based on the results of its experience with the first phase.

5 Meeting the EEDI requirements with MAN Diesel & Turbo To comply with the EEDI, ships need to be fitted with efficient, well-designed technology. MAN Diesel & Turbo offers a comprehensive range of solutions, including engines, turbochargers and propellers. Built entirely by MAN Diesel & Turbo, these systems reflect the high quality standards that have made us a world leader. Highly efficient engines As gas contains less carbon, running engines on liquid natural gas (LNG) produces far lower emissions. This leads to a significantly reduced EEDI. MAN Diesel & Turbo has recently introduced a range of extremely efficient and versatile dual-fuel engines, suitable for almost all types of shipping. These allow shipowners to benefit from the increasing availability and attractive price of gas, yet offer full fuel flexibility. Multiple combinations MAN Diesel & Turbo offers a wide range of energy efficiency devices to provide the optimum solution for your vessel. One of the most efficient ways to optimise your vessel is through the use of Kappel propellers in combination with a rudder bulb. Whether your engine is driven by liquid or gaseous fuels, this increases the efficiency of your vessel up to 10%.

6 Waste heat recovery The more efficient an engine is, the more power it obtains from the same amount of fuel. At MAN Diesel & Turbo, we have the expertise to maximise this output: for example, by making use of the heat given off by the combustion process, which can be recovered from the cooling water and exhaust gases. In fact, up to ten per cent more power can be obtained using an effective waste heat recovery system. The energy recovered by this system can be used to heat accommodation, fuel and/or cargo, or power a steam turbine and generator. 15% exhaust gas losses power generation, air conditioning heat recovery hot water heat recovery steam 17% thermal energy recovery freshwater generation electrical propulsion 30% 15% generators 45% 32% 4 engines, 1 stand-by 11% 12% seawater cooling losses Typical energy heat balance of a cruise ship Carbon Factors Shaft power output: 47,34% Gain: 11,0% EI, power production of TES: 5,0% Lubricating oil cooler: 4,6% Jacket water cooler: 4,4% Exhaust gas and condenser: 13,6% Air cooler: 17,1% Heat radiation: 2,2% Fuel 100% 9L48/60CR at 85% MCR 10 EEDI Energy Efficiency Design Index EEDI Energy Efficiency Design Index 11
