Total recordable injury frequency
Definition : The number of fatalities, lost-time injuries, cases of alternative work necessitated by an injury and other recordable injuries, excluding first-aid injuries per million working hours.
Developments : The total recordable injury frequency (including both StatoilHydro employees and contractors) increased from 5.0 in 2007 to 5.4 in 2008. The frequency for StatoilHydro employees decreased from 3.5 in 2007 to 3.4 in 2008, while the frequency for our contractors increased from 6.1 in 2007 to 6.6 in 2008.
Lost-time injury frequency
Definition : The number of lost-time injuries and fatal accidents per million working hours.
Developments : The lost-time injury frequency (including both StatoilHydro employees and contractors) increased from 2.0 in 2007 to 2.1 in 2008. The frequency for StatoilHydro employees was 1.7 in 2008, the same as in 2007, and for our contractors the lost-time injury frequency increased from 2.2 in 2007 to 2.3 in 2008.
Serious incident frequency
Definition : The number of incidents of a very serious nature per million working hours (1).
Developments : The serious incident frequency (including StatoilHydro employees and contractors) increased from 2.1 in 2007 to 2.2 in 2008 and is now at the same level as in 2006.
(1) An incident is an event or chain of events that has caused or could have caused injury, illness and/or damage to/loss of property, the environment or a third party. Matrices for categorisation have been established where all undesirable incidents are categorised according to the degree of seriousness, and this forms the basis for follow-up in the form of notification, investigation, reporting, analysis, experience transfer and improvement.
Sick leave
Definition : The total number of days of sickness absence as a percentage of possible working days (StatoilHydro employees).
Developments : Sickness absence in StatoilHydro has been stable at 3.5% for the last three years, but increased in 2008 to 3.7%. It is still low compared with similar industries, and it is closely followed up by managers at all levels.
Oil spills
Definition : Accidental oil spills to the natural environment from StatoilHydro operations (in cubic metres) (2).
Developments : The number of accidental oil spills was 401 in 2008 as against 387 in 2007. The volume of accidental spills has decreased from 4,989 cubic metres in 2007 to 342 cubic metres in 2008. The figure shows the volume of oil spills in cubic metres.
(2) All accidental oil spills reaching the natural environment from StatoilHydro operations are included in the figure.
Carbon dioxide emissions
Definition : Total emissions of carbon dioxide in million tonnes from StatoilHydro-operated activities (3)
Developments : Carbon dioxide emissions in 2008 have been as expected and approximately the same in 2007. Carbon dioxide emissions decreased from 14.6 million tonnes in 2007 to 14.4 million tonnes in 2008. Entering the production phase at Snøhvit at the beginning of the year caused increased emissions, while planned maintenance during the summer at several EPN installations reduced emissions. There has been a small increase in CO2 emissions in NG and a small decrease in CO2 emissions in M&M due to planned maintenance and closure of plants.
(3) Carbon dioxide emissions include carbon dioxide from energy and heat production in own plants, flaring, residual emissions from carbon dioxide capture and treatment plants, process emissions, emissions of carbon dioxide as a consequence of gross energy (electric power and heat) imported from a third party (indirect emission), emissions of carbon dioxide as a consequence of exported energy to a third party.
Nitrogen oxides emissions
Definition : Total emissions of nitrogen oxides in thousand tonnes from StatoilHydro-operated activities (4)
Developments : Emissions of NOx in 2008 have been as expected and slightly lower than in 2007. Nitrogen oxides emissions have decreased from 49.4 thousand tonnes in 2007 to 46.7 thousand tonnes in 2008. There has been a minor reduction in the overall EPN NOx emissions due to the use of a lower NOx emission factor. The new NOx factor has been decided in an agreement between the authorities and the petroleum industry as a result of the introduction of NOx tax. There has been a small increase in NOx emissions in NG and a small decrease in NOx emissions in M&M due to planned maintenance and closure of plants.
(4) Nitrogen oxide emissions include all emission sources and include nitrogen oxides from energy and heat production in own plant, transportation of products, flaring and treatment plants.
Energy consumption
Definition : Total energy consumption in terawatt-hours (TWh) for StatoilHydro-operated activities (5)
Developments : Energy consumption in 2008 has been as expected and approximately the same as for the year 2007. Energy consumption has decreased from 69.8 TWh in 2007 to 69.6 TWh in 2008. Energy consumption and the CO2 emissions basically follow the same pattern. There has been an increase in energy consumption in NG due to non-utilised energy from the VOC incinerator at Kårstø. There has been a small decrease in energy consumption in M&M due to planned maintenance and closure of plants.
(5) Energy consumption includes energy consumed in producing the facility's deliveries or by performing an activity, that is the sum of imported energy, energy generated by own activity and unused energy minus delivered/sold energy.
This includes energy from power and heat production based on combustion, unused energy from flaring (including well testing/well work-over and venting), energy sold/delivered to third party, net energy (heat and electricity) imported from contractor, gross energy (heat and electricity) imported from contractor.
Non hazardous waste recovery rate
Definition : The recovery rate for non-hazardous waste comprises non-hazardous waste from StatoilHydro operated activities and represents the amount of non-hazardous waste for recovery as a proportion of the total quantity of non-hazardous waste (6)
Developments : The recovery rate for non-hazardous waste has decreased from 41% in 2007 to 29% in 2008. The non hazardous waste recovery rate shows a negative trend compared to previous years. The main change is within M&M, but there are uncertainties in data. During 2009, there will be focus on quality assurance of data from all parts of M&M.
(6) The quantity of non-hazardous waste for recovery is the total quantity of non-hazardous waste from the plant's operations which has been delivered for re-use, recycled or incinerated with energy recovery
