With an initial order for centralisers, cement top-up systems and cutting and tensioning equipment to the value of around £500,000, the four year agreement includes the complete Aquaterra Energy product and service range.

At a water depth of around 70m, the Hejre development comprises manned wellhead and processing platform, and five HTHP production wells.

DONG Energy that owns a 60% stake in the Hejre field and its partner Bayerngas Norge, which has 40% interest, are planning to invest about £1.3bn in the development, in together, while the field is expected to come online in 2016.

Aquaterra Energy Europe regional director Eric Doyle said the Quality and service are particularly important considerations for DONG Energy in selecting partner companies.

"This significant contract is our largest to date with the Danish state energy company, which has worked with one other supplier for many years," Doyle added.

DONG Energy, which is partly owned by the Danish government, has generated £8.1bn in revenues in 2013.
