5.5 Environmental Behavior during the Operational Life of the ChainWithin the operational phase of the life-cycle we have only taken into accounttransportation of the chain by vessel (the only possible method of transport due tovolume and weight) to the place in which the chain will be used by the client. Toestimate the distance that the vessel will travel we have based our evaluation on otherorders delivered in the year 2008, and then an estimation of the average distance foreach journey. Finally, calculating the weighted mean total for the year:NumberofJourneysDestinationEstimateddistance(km)Tons.Journeys xDistance xTons.Tons/Kilometreexpressed asfunctionalunits.5 Gulf of Mexico 8,300 3,853 127,919,6007 Norway 3,000 332 5,976,0002 West Africa 4,500 8,581 193,072,50019,8844 Europa - Russia 1,500 4,728 21,276,000The delivery method is using transoceanic freight ship.The environmental impact is measured according tothe number of tons of chain transported and thenumber of kilometers travelled. Within this indicator wetake into account the production and maintenance ofthe vessel, the port and the average consumption offuels and resources (Ecoinvent Data 2.0: transport,transoceanic freight ship, OCE, [tkm] (#1968)).21/25
