Resource Conservation and Waste ReductionE n v i r o n m e n t a l R e p o r tThe structure of across-head engineExhaust valveExhaustLubrication portsLubricatorPistonAir supplyPiston rodCross-headCrankshaftPromotion of Installation of LubricantM/E Cylinder OilConsumption-saving EquipmentThe vessels owned by Shinwa Kaiun that have cross-head engines are beingconverted from mechanical to electronically controlled lubricators to reduce theamount of lubrication and lower cylinder oil consumption.Cross-head engines use two types of lubricant: cylinder oil in the cylinder liner andsystem oil in the crankcase. The system oil undergoes a circulation cycle so that it canbe reused. The cylinder oil, however, cannot be reused because it is burned up insidethe cylinders, and this oil must be fed in constantly for the engine to continue operating.There used to be mechanical lubricators attached directly to the engine. These wouldfeed oil at a fixed frequency once every one or two revolutions of the engine. Now,however, electronically controlled lubricators have made it possible to feed oilaccurately and in a way that is appropriate to the main engine's current operationalstatus. Reducing the wasteful feeding of oil makes it possible to reduce the amountof lubrication and lower the consumption of cylinder oil. Shinwa Kaiun is activelyengaged in fitting electronically controlled lubricators.Use of Fuel Additives Sludge Dispersantsto Improve Energy-saving EffectivenessLarge ships are ordinarily fueled by residual fuel, which is what remains after gasoline,diesel oil, and other light components have been extracted from crude oil. In fact theyuse a low grade of heavy oil known as heavy fuel oil. This heavy fuel oil contains asubstance known as asphaltene high-density hydrocarbonthat can agglutinate andform sludge when the fuel is heated or mixed. Asphaltene is a causal factor in variousproblems, such as precipitation in fuel tanks and increased fuel loss, causingequipment problems when it is caught in strainers, and so on. Heavy fuel oil hastended to become an even lower-grade fuel in recent years as the demand for lightfuels such as gasoline and diesel oil has increased. Sludge countermeasures haveaccordingly taken on increased importance for both economic and safety reasons.Shinwa Kaiun places fuel additives sludge dispersantsin the fuel for its ships toprevent the formation of asphaltene sludge. The purpose is to save energy byefficient use of fuel and improve safety by reducing sludge.Asphaltene forms sludgeHeavy fuel oilAdditive sludge dispersantaddedAsphaltenehigh-density hydrocarbonAdditive-freeAsphaltene sludgeis formed by heatingor mixing ofdifferent types of oil.It dispersesthroughout the HFOand becomes fuel.

Shoyo Maru of Shinwa Naiko Kaiun Kaisha, Ltd.,transporting fly ash for recycling resourcesWaste segregation in the officeReduction of Power Consumption in the OfficeReduction of power consumption has cut annual power usage at our offices by1% in comparison with the previous year. Using this as our environmentalslogan, we are making efforts day and night to reduce annual powerconsumption at our offices, encouraging power savings with such practices asturning off unused office machines and unnecessary lights.In fiscal year 2007, however, increased use of computers and air conditioningresulting from the growth in operations caused by active sales expansionproduced a rise in electric power demand. This resulted in an increase of 1%over the previous fiscal year. We intend to continue our efforts from the previousfiscal year to achieve the target.Office WasteFor thorough separation of waste generated in offices, we have improved thearrangement of waste baskets, and are running an in-house campaign to implementwaste segregation in compliance with local regulations. In addition, we promote theeffective use of recyclables: since last fiscal year we have encouraged reusing blankreverse sides of used paper, and using personal coffee and tea cups instead ofdisposable ones.E n v i r o n m e n t a l R e p o r tProper disposal of onboard wasteProper Disposal of Onboard WasteVarious kinds of waste are generated by the crew living on board. Such onboard wasteis thoroughly separated and collected as is done on shore, and is either burned onboard or duly disposed of on shore, except items suitable for ocean disposal afterpulverization, such as food waste. By setting a target for shipboard waste disposedashore an increase of 1% over the previous fiscal year, Shinwa Kaiun is managing thevolumes and methods of shipboard waste being disposed aboard and ashore.Environmental EducationSeamen's Environmental EducationThe company has formulated and implemented onboard education and trainingthrough On-the-Job Training OJTin addition to classroom training for crews. Theplan includes items related to environmental protection, which serves to bring aboutseamen's awareness of environmental protection through pre-boarding seminars.Environmental Seminar in ManilaClassroom training in ManilaTwice a year, the company dispatches lecturers to hold seminars for Philippineseamen on leave, holds lectures on the environmental management system andstrives to increase environmental awareness among the seamen.Shinwa Kaiun Group CSR Report 2008 19
