Peae eain e irane enirn- ena ie in reain DN era iin ariie and re Trad Understanding environmental issues and supporting our customers withthe associated risks and opportunities isfundamental to our objective of, safe- guarding life, property and the environ- ment. Dealing efficiently with environmental risks is imperative for the longer term sustainability of an organization or in- dustry, and a key part of being prepared for changing frame conditions in terms ofcosts of fuel, technology and other ele-ments, incentive structure, regulations, technology development and stakeholder expectations. As an international risk managementcompany, it is essential that we can help our customers to understand the criticalrisks and to manage them professionally. For environmental risks, DN has taken a holistic approach that looks at emis-sions, waste, and resource depletion. We have developed a methodology that sup- port decision making on short and longterm cost efficient environmental meas- ures for a specific ship or fleet. For us, there is no doubt that environ- mental issues are important, and that theframe conditions in this area are changingrapidly, as evidenced by the ballast water convention, anti-fouling coating and the MARPOL convention for air emissions. Can y are i e r deeen r DN a y ink ae e e ane draaiay rede e arn rin i Trad The DN concept ships, uan- tum for container ships and Triality for LCCs show real innovation to dramati- cally reduce the carbon footprint of ships.They promise improved environmental performance, technically advanced de- signs and solid economic performance.The hull design allows for a ballast free ship, the propellers remain submerged when the ship is empty and liquefied nat- ural gas, rather than heavy oil is used for fuel. LN fuel will significantly reduce air emissions and, in the case of Triality, volatile organic compounds are con- densed and used as fuel for the auxiliaryboilers. Second, DN?s Environmental and Energy Efficiency Rating System, Triple E, has been developed to provide ship operators with a tool to improve or- ganizational performance, identify ways to minimize the environmental impact and, ultimately, optimize fuel consump- tion and reduce costs.Also, DN has more than 40 years of ex- perience with LN ship operations and was an early pioneer for using LN fuel for ship propulsion in 2001. Today, there are over 20 LN fueled ships in opera- tion. A LN fuelled ship reduces the emissions of NOx by 50, and SOx and particles by close to 100 compared to today?s fuel. In addition LN fuelled ships provide a 1520 reduction in net greenhouse gas emissions.LNG a Fe Te ne ee e ainin rain a aene d y ee a e ere ake LNG ered i re ainrea Trad One challenge is that the infra-structure is not in place today. eer ere ere ere n aine a- in in e US S I eiee a a e deand r LNG e inreae e- anin-inded i anie i de- e e inrarre I ink e e r Fied Drea i r eninin I y id i ey i e In the immediate future, there arevery good economic and environmental arguments for using LN fuel in short sea shipping or for offshore support ves- sels in the ulf of Mexico. Another challenge is the perceived safety risks of LN fuel, in particular related to infrastructure and terminals. Many of the concerns and opinions raised don?t re- flect past and current experience with LN. Natural gas is already used widely in North America for electrical power generation, heating and cooking. An ex- tensive pipeline grid across the entire country distributes natural gas to con- sumers, and hundreds of LN tanker trucks are already delivering natural gas in the form of LN across North Amer- ica. The industry does need to demon- strate to the public that all of the riskshave been fully assessed and that there are safety regulations and other systems in place to manage those risks. Wa D Say a iner ay I rea i Trad In our paper, reener hipping in North America , we described our eco-nomic models for the three alternatives to meet emission control area requirements:Switch to low sulfur fuel, install an ex- haust gas scrubber, or switch to LN fuel. Today, we estimate that new ships with LN propulsion may cost 10-20 more, mainly due to the LN storage tanks, the fuel piping and, in some cases,a slightly larger ship. Of course, this cost differential will diminish as we gain ex- perience in design and constructing LNfuelled ships. However, with projected fuel pricing over a 20 year operating pe- riod, our economic calculations show that LN is a clear winner. The LN fuel op- tion has lowest present value of costs. It is 4 million less than the scrubber op- tion and 12 million less than a marine gas oil option.
