Hejre The installation work in the North Sea has started

292 kilometres north west of Esbjerg, the support structure for DONG Energy's Hejre platform is now well planted in the North Sea.

Facts on the Hejre field

  • The Hejre licence is owned by DONG Energy (60%), operator of the licence, and Bayerngas (40%)
  • Water depth: 68 metres
  • Reservoir depth: 5000-6000 metres
  • Reservoir pressure: 1010 bar
  • Reservoir temperature: 160 °C
  • First production of oil and gas is expected in 2016
  • The field's reserves are estimated to be approximately 170 million barrels of oil equivalents
  • The oil production alone corresponds to twice the Danish total annual oil consumption
  • The development of the Hejre field generates almost 500 permanent jobs in Esbjerg, Fredericia and Copenhagen
Now, the first physical signs of a new platform in the North Sea are there. The 8.400-tonne steel structure, called a jacket, which is the support structure of the Hejre platform, arrived at its location in the Danish sector of the North Sea on 22 May, and the last steel pile for fastening the legs of the support structure were rammed into the subsoil on Friday 30 May. Now, drilling of the production wells will start.

”Our people on the project and our suppliers have done a fantastic job in delivering and installing the jacket in the North Sea. Now, we enter a new project phase. where we will be drilling the production wells, installing the oil and gas pipelines and modify the Gorm E platform from which the oil will be transported to shore," says Flemming Horn Nielsen, head of DONG Energy's Danish oil and gas business.

Launched in less than one minute

The launch of the jacket from a barge into the North Sea took less than one minute. The ballast tanks of the barge were filled with water, making it tilt slightly, so that the giant steel construction slid into the sea. The fitted floating tanks and compartments in the construction kept it floating, before it was erected to a vertical position in a controlled process and lowered onto the seabed.

Next year's milestone is the installation of the topsides which is currently being built at a yard in South Korea.
