Norwegian oil and gas major Statoil has installed a drilling platform jacket on the Johan Sverdrup field development located in the North Sea.
Statoil last Friday launched a video of the jacket installation, which was performed “during spring 2018.” This is now the second visible structure on the Johan Sverdrup field.
Built by Kvaerner’s Verdal yard in Norway, the 21,300 tonne heavy drilling platform jacket was named Vilje in March. Vilje was the second jacket to be built by Kvaerner for the giant Sverdrup development.
The first one, for the riser platform, was completed in June 2017 and named Aegir . It was installed on the field last year using the Thialf crane vessel owned by Heerema Marine Contractors.
According to Statoil, the next step in its Sverdrup 2018 campaign entails installation of the riser platform topside, which will be the first topside on the field. This will be followed by more than 400 km of pipelines and 200 km of power cables.
As previously reported by Offshore Energy Today, t opsides for the drilling and riser platforms are currently at Aibel’s yard in Haugesund undergoing final preparations before sailaway to the field.
The riser platform is expected to head to the field later this month and the drilling platform will leave the yard in the turn of the month May/June.
The Statoil-operated Johan Sverdrup field will be developed in phases. The first phase involves the establishment of a field center consisting of four platforms, including a utility and living quarters platform, a processing platform, a drilling platform and a riser platform. The platforms will be interlinked by gangways.
Production start-up is scheduled for end 2019 with production capacity estimated at 440,000 barrels of oil per day.
The plan for development and operation (PDO) for phase 2 will be submitted before September 2018. Phase 2 is expected to start up in 2022, with full field production estimated at 660,000 barrels of oil per day.
