ME-GI engine showed up at pier No. 4 in Masan port (Masanhappo-gu, Changwon-si) in June 15th, 2014. It took 5 hours to load the ME-GI engine from the barge to the vessel. The vessel containing this engine will leave Masan port on 16th and will arrive at NASSCO shipyard in San Diego on the 5th or 6th of July. We have led the commercialization of the world’s first LNG fueled vessels by contracting with NASSCO shipyard to design an LNG powered container ship and to supply material packages in December, 2012. As we can deliver ME-GI engine successfully after the core systems of this vessel such as the main engine (ME-GI), the Dual Fuel Diesel Generator (DFDG) and the Fuel Gas Supply System (FGSS) passed through extensive Factory Acceptance Test (*FAT), we are achieving definite business results. An LNG powered container ship with ME-GI engine does not only reduce carbon dioxide emissions by 23%, nitrogen oxide emissions by 25% and sulfur oxide emission by 99% compared to the heavy fuel oil powered vessels, but it also cuts down on fuel expenses. As a result, LNG fuel will open up a new era in the shipping industry by ensuring cost-efficiency and sustainability. Changing the fuel system of a vessel is not a simple problem. In order to use LNG, which needs to be in cryogenic condition to sail through heavy weather forlong stretches, complex factors such as the gas fueled engine (ME-GI), the liquid fuel injection system (FGSS) and the LNG storage tank in the vessel should be installed in such a way as to play their individual roles effectively without any systematic risk or errors. In other words, it is impossible to go ahead if “perfect technical skills to change the heart of the vessel” do not accompany. The fact that we have designed a LNG powered container ship and loaded M/E successfully is of great significance. This indicates that DSEC has core competencies for the development and operation of the LNG storage tanks, which is essential for using LNG safely and effectively for vessel fuel. It also proves that our design engineering capacity, which is required for the integrated operation with the relevant systems, is comprehensively verified. Moreover, we are accelerating additional research and development to accomplish competitive technology such as the development of LNG storage tanks using new advanced materials, called high manganese steel.

<DSEC, Cruising with the Winds of Eco-friendly and High Efficiency> DSEC co. ltd., Cruising with the Winds of Eco-friendly and High Efficiency “Leading the shipbuilding Industry with R&D Capabilities in Eco-Ship Technology” Steam engine ships appeared in 1812. A hundred years later, the diesel engine was developed. Again, after another hundred years, there are pioneers who are trying to take LNG-propelled ships to mainstream. In the recent 10 years, the price of fuel oil has soared 6~7 times up, equaling 600 USD per ton. Following this trend, the shipping companies shifted their focus of competition from speed—how to ship in the shortest amount of time—to mileage, or, how to ship by using as little fuel as possible. In addition, the Energy Efficiency Design Index (EEDI) has taken effect as of January 1st, 2013, by the International Maritime Organization (IMO), which regulates the emission allowance of CO2 down by 10% by 2015, 20% by 2020, 30% by 2030, for every ton-mile of seaborne travel, a policy that would only raise the importance of Eco-Ships as ever. The Core of Eco-Ship Development is “High Pressure Natural Gas Supply System (FGSS)” Unlike other shipbuilding companies that are not capable of responding to the changes of time in requirements of eco-friendly and high efficiency, DSEC has adopted the natural gas engine (ME-GI) made by one of the biggest engine manufacturer, MAN Diesel & Turbo (MDT). In addition, we have also won a contract with NASSCO to design the world’s first LNG-fueled container eco-ship to design and supply packages which is showing the world of something to pay attention to. Before the natural gas engine (ME-GI) was developed by MDT, there was no way to adapt LNG fuel for large ships. Although the development of the engine was complete, the remaining task was to develop equipment that would vaporize LNG in order to feed the engine. Named “High Pressure Natural Gas Supply System (FGSS)”, while working at DSME as the head manager of Okpo shipyard, the equipment was finally completed by the CEO of our company Mr. Young-man Lee who devoted his heart and soul for its development, making possible to use LNG fuel in large ships. Recently, the next generation ‘eco-friendly’ ship equipped with the FGSS, renowned as the best ‘Natural Gas Fuel Ship’, has transformed the traditional fuelling system using existing bunker-C oil into natural gas which not only reduces fuel cost by half, but also dramatically reduces the emission of pollutants. Further on, DSEC’s FGSS is expected to extend its importance in the shipbuilding market as the core technology for using natural gas fuel. In addition, the LNG-propelled and eco-friendly large container carriers will be able to reduce CO2 by 23%, NOx by 25% and SOx by 99% when compared to ships propelled by common heavy oil. The fuel consumption will also be reduced by 35%, which satisfies both the aspects of economic feasibility and the environment. How Are Energy Reduction in Ships Being Done in the Age of High Oil Prices? Remodeling the bulbous bow, the front lower portion of the vessel which is projected out, into a structure most appropriate to aerodynamic wave drag through computational analysis, can save annual fuel cost by 600,000 USD. DSEC applied this method for the first time in Korea to Hyundai Merchant Marine Co. Ltd. Additionally DSEC also successfully provided the design of the bulbous bow remodeling to ships operated by ZODIAC and HOEGH AUTOLINERS. The PSS, or Pre-Swirl Stator, which is positioned at the backside of the vessel and located right in front of the vessel’s propeller in the form of wings, equals the flow of water which is flown from the stern and into the propeller raising the efficiency of mileage. DSEC, through industrial-academic cooperation with Busan National University, has completed the design of PSS suitable for ‘LNG-propelled eco-friendly large container ships’ currently in construction at NASSCO shipyard and is predicted to result in 3~5% of fuel consumption. DSEC’s CEO Mr. Young-Man Lee explains, “Following the rise in demand for vessels that use alternative fuels to the Climate Change, our company is set to take the lead in eco-friendly and high efficiency trends in the shipbuilding industry by embracing various demands from shipping companies.” The natural gas engine (especially MDT’s ME-GI), which will be equipped on the eco-friendly large container ship which uses LNG fuel by adapting the FGSS, is currently being tested by Doosan Engine and is planned to be delivered to NASSCO in May.

< DSEC Spurs Order-Receiving Efforts for a Triumphant Finale of 2013 > With the year 2013, our company’s efforts are continuously in action to win the biggest contract in history. By preceding the ECO-Tanker, which boasts its globally recognized fuel efficiency, our company is on the brink of signing a contract with America’s shipyard, NASSCO to consecutively design and supply materials. In addition to signing contracts to design and supply materials of the world’s first LNG propelled ship, our company is achieving the most outstanding results even in the era of economic stagnation for shipping industries. In addition, we have won a contract in December, 2013 to construct the world’s first TOTE 3,100TEU LNG Fuelled Containership, which is judged as the world’s most revolutionary event. Again in June, 2013, we have won a contract on APT ECO MR Tanker which is recognized for its energy efficiency, which is globally leading. This incident has been a moment for our company to be acknowledged once again for its outstanding technology and differentiated competitiveness. In September, a construction contract wan made to build two ECO MR Tankers with companies SEACOR and NASSACO. Shortly, contracts to design and supply materials will be made with our company and NASSCO. In addition, for active agreements on concluding an agreement to order 4,100TEU type containerships which ship-owner MATSON schedules to order, we also are looking forward to good news. As an additional remark, our company is spurring in new businesses such as new ship designs, supplying materials and others. We have made contracts with Hyundai Merchant Marine, ZODIAC, HOEGH AUTOLINERS in remodeling Bulbous bow which is being operated on existing ships. Furthermore, from many ship-owners, remodeling of additional installation of BWMS and a series of business inquiries on the Energy Saving Program are made. In addition, our company is working to supply yard facilities and operation skills, from NASSCO shipyard’s Yard Operating and Facilities Improvement consulting, to Bath Iron Works shipyard (battleship construction shipyard) affiliated with General Dynamics, to Canada’s Irving shipyard and Brazilian shipyards. NASSCO in particular, is consulting with our firm about modernizing and increasing production to digest their overloading orders by doubling their construction. Through this, NASSCO shipyard has become the ‘1st trade record’ within the consulting business. This project will indeed strengthen the bond between our company and NASSCO. Not only is our company promoting a solid relationship with NASSCO shipyard as strategic partners but also through dynamism in business, we are increasing our reputation as a ‘TOTAL MARINE AND POWER PLANT COMPANY’.
