Johan Sverdrup lies in the Norwegian North Sea, about 40km south of Grane, 65km north of Sleipner and 140km west of Stavanger.
Its gas will be exported to Kårstø via a new 18in pipeline, tied into the Statpipe rich-gas leg from Statfjord with the aid of hot tapping and connection to a 30in retrofit tee.
Installation will be diverless, using hot tapping equipment from the pipeline repair system (PRS) base in Haugesund.
Johan Sverdrup is one of the five largest oil fields on the Norwegian continental shelf. With estimated resources of 1.7-3 billion bbl, it will rank as one of Norway’s most important industrial projects over the next half-century.
The field is due to come on stream in December 2019, and to continue producing for 50 years.
Gassco will serve as the operator and technical manager of the 156km pipeline from the riser platform on Johan Sverdrup to the Statpipe rich-gas leg once the field comes on stream. Statoil is the development operator.
