Denmark-based energy company Dong Energy has shut down production after an annual inspection discovered small cracks in a water tank connected to the oil storage tank below the Siri platform.
No oil has been spilled as a result of the cracks, but Dong immediately decided to shut down production and subsequently emptied the oil storage tank to eliminate the risk of a spill while an investigation is ongoing.
The temporary closure has stopped production from the Siri, Stine, Nini and Cecilie fields, and manning of the platform will be reduced to a minimum. As the investigation is still underway, it is not yet possible to estimate when production can be restarted.
The Siri platform, which started production from the Siri field in 1999, is the central processing and offloading facility in the cluster with accommodations for 60 people. In 2008, the total production in the area was 6.4 million barrels (bbl), corresponding to a daily production of about 17,500 bbl. The integrated jackup platform is situated in a depth of 60 m approximately 250 km off the western coast of Denmark. Oil is stored in a 50,000m³ tank on the seabed before being offloaded into tankers for export.
