The Challenges of Climate Change It s time to act We are seeing unprecedented climate change threaten our vital, yet fragile ecosystems. The knock-on effects of rising temperatures caused by greenhouse gas emissions such as carbon dioxide (CO 2 ) could have disastrous effects on global agriculture and trade. That s why it has never been more important to limit the cause and effects for future generations. Shipping makes a difference Maritime transport will continue to expand with increasing globalization, and although shipping already counts as the most efficient form of bulk transportation, the industry has recognized that more can be done. Optimized engines and improved designs lay the foundations for positive change. Working with key stakeholders, the International Maritime Organization (IMO) has outlined new standards for greater efficiency throughout all stages of a ship s lifecycle. One such measure, the Energy Efficiency Design Index (EEDI), is a perfect example of this ambitious goal. It pays to get on board With the international shipping industry so committed to ensuring positive change, it will be crucial for individual ship owners and operators to move with the tide. Market-based measures such as levies or emissions trading are foreseeable in the future, and this will only create further incentives to invest in efficient ships. Though final decisions have not yet been made in this respect, the IMO is certainly considering the possibility. So now is the time to act.

Energy Efficiency Design Index IMO regulations in a nutshell What is it? The EEDI is used to calculate a vessel s energy efficiency. This is based on a complex formula, taking the ship s emissions, capacity and speed into account. The lower a ship s EEDI, the more energyefficient it is and the lower its negative impact on the environment. IMO regulations stipulate that ships must meet a minimum energy efficiency requirement, so their EEDI must not exceed a given threshold. Targeted requirements At present, the EEDI only applies to the worst offenders when it comes to maritime pollution. In other words: the vessels responsible for the most emissions. Ships commissioned after January 1, 2013 and weighing 400 GT or more will have to meet the new requirements. Older vessels are only affected by the EEDI standards if they have undergone a major retrofit in recent years. CO 2 emissions EEDI = = Benefit Cargo P Cf SFC Capacity speed That said, ship owners and operators would be wise to consider that EEDI requirements will gradually be tightened: ships built in 2015, 2020 and 2025 will have to meet even higher standards. Not a one-size-fits-all approach Vessels featuring diesel-electric, gas turbine or hybrid propulsion are currently not required to meet EEDI standards. RoRo, RoPax, cruise, offshore and other vessels not explicitly mentioned in the regulations are also exempt. However, based on the results observed in the first phase of the initiative, the IMO intends to expand the EEDI to include additional types of ships in the future. Here too, it will be invaluable for ship operators to keep abreast of the changes.

This begins with a baseline value set for the year 2013, which is then raised successively in three stages until 2025. The baseline for the required EEDI is a function of the EEDI for vessels built after the year 2000. Relevant energy consumption The EEDI assesses the energy consumption of a vessel under normal seafaring conditions, taking into account the energy required for propulsion and the hotel load for the crew. Energy consumed to maintain the cargo and for maneuvering or ballasting is not considered.

Meeting the EEDI Requirements Optimized engines and components Only ships fitted with state-of-the-art technology will stand a chance of complying with the EEDI. This is where MAN Diesel & Turbo steps in as a competent partner to industry. Our comprehensive range of solutions including engines, turbochargers and propellers reflects the high standards that have made us a market leader across the seven seas. Banking on efficiency Burning liquefied natural gas (LNG) produces less CO 2 than other conventional sources, making it a powerful alternative in achieving a significantly reduced EEDI. MAN Diesel & Turbo has recently introduced a range of extremely efficient and versatile dual-fuel engines, suitable for almost any type of shipping. With these engine models, ship owners benefit from attractive gas prices and full fuel flexibility.
