1) Gassco AS is operator for the plant, but StatoilHydro is the technical service provider (TSP).
2) Except gas transport from TN: 24 mill tonnes.
3), 4), 5), 6), 7) Included emissions from Draupner, SO2: 0,20 tonnes, NOx: 22 tonnes, nmVOC: 29 tonnes, CH4: 144 tonnes, CO2: 13,903 tonnes.
8) Non-hazardous waste included from Draupner: 8 tonnes for deposition and 68 tonnes for recovery.
9) Hazardous waste included from Draupner; 4 tonnes for deposition and 71 tonnes for recovery.
10) Emissions from the terminals in Germany, Belgium and France are not included in the emissions due to that Gassco is the operator for the terminals.
11) Included fuel gas from TN: 67 GWh, Draupner 2.1 GWh. |
