In July 2017, DeepOcean was awarded an EPCI contract for performing remote hyperbaric tie-in of the oil export pipeline on the Johan Sverdrup field.
The award covered project management, engineering, procurement and installation of the 36 inch oil export spool and remote hyperbaric tie-in of the oil export pipeline to the Johan Sverdrup riser platform with Statoil’s remote welding spread from the Pipeline Repair System (PRS) base on Killingøy, Haugesund.
Offshore execution was performed with DeepOcean’s construction vessel Edda Freya.
The Johan Sverdrup is one of the five largest fields ever discovered on the Norwegian continental shelf, in the North Sea, about 140 kilometres (87 mi) west of Stavanger, Norway.
The field is in 110 to 120 metres water depth, and the reservoir is at 1900 meters depth.
Peak production is estimated to be over 500,000 barrels per day (79,000 m3/d), which will make it by far the largest producing oil field in the North Sea.
