Our top priority is to be a safe and trustworthy company. This is why Exploration & Production is continually making QHSSE improvements in all its activities, both offshore and onshore.

We do everything we can to protect the health and safety of our employees, to ensure the integrity of our technical installations, and to minimise the environmental impact of our activities.

The slogan "The Safe Way or No Way" reflects the safety culture prevailing in Exploration & Production, whether the employees plan, analyse, conclude contracts, undertake procurement, construction, building activities, operation or maintenance.

Discharges to sea of oil-containing produced water from DONG Energy’s oil and gas extraction activities were 8 tonnes in 2010, an improvement of 56% on 2009, when discharges totalled 18 tonnes.

The discharge of oil at the DONG Energy-operated Siri platform was 2.7 tonnes in 2010. This corresponds to an average concentration of oil in the water discharged from the platform to the North Sea of 12 mg of oil per litre of water. The improvement primarily reflected the fact that DONG Energy maintained its purifying efficiency while at the same time significantly increasing reinjection of produced water into the reservoir. Reinjection of water with oil residues increased to 78% in 2010 from 49% in 2009. The Siri platform improved its reinjection performance from 78% of produced water in 2009 to 94% in 2010.

Natural gas flaring at the Siri platform increased to 29 million Nm3 in 2010 from 2 million Nm3 in 2009, causing an increase in EU ETS CO2 emissions. The increase was due to production from a new satellite platform, Nini Ost, which is  tied in with the Siri platform. The flaring was a consequence of challenges in connection with the treatment of gas from the new field in the processing system on Siri. The processing system on Siri was modified in January 2011, and this is expected to result in a significant reduction in flaring in 2011.
