With repair work at full speed during spring, the clamps intended to hold the cables between the platform legs in place, were installed.

 

DONG Energy has resumed production under normal conditions in the Siri area after having used a temporary solution for more than six months.


The oil from DONG Energy's oil fields in the North Sea: Siri, Nini, Nini East, Cecilie and Stine-1, is now sent directly to the oil tank below the Siri platform. This takes place after completion of extensive repair work lasting several years.

 

Flemming Horn Nielsen, Country Responsible for DONG Energy's Danish oil and gas activities, said: "It’s a milestone that we've resumed producing to the oil tank. The Siri repair work has been a huge project for the organisation.  We were faced with a complex offshore project where we had to optimise the design and construction solutions on a regular basis. Throughout the period, our employees have delivered a fantastic job." said Flemming Horn Nielsen, Country Responsible for DONG Energy’s Danish oil and gas activities.

 

As previously announced, the Danish Energy Agency's final approval of the repair solution is still pending.

Background for the Siri repair work

  • In August 2009, DONG Energy decided to stop production in the Siri area. Reason: During a routine inspection, cracks were discovered in the aqueous section of the sponson in the oil tank below the Siri platform.
  • In January 2010, production was resumed in the area after installation of temporary support measures at the Siri platform.
  • In May 2011, the concept of a permanent repair solution was selected.
  • Production was shut down again in July 2013, because a crack was discovered in a critical area.
  • In January 2014, as a temporary solution, the satellite fields connected to Siri, ie Nini, Nini East and Cecilie, started producing via Siri’s processing facilities directly to a tanker.
  • In July 2014, Stine Segment-1 and some of the Siri wells started producing again.
  • In September 2014, the final pipework was performed so that the oil can run into the subsea tank.
