Statoil has started steel cutting for a riser platform jacket to be used in the drilling of Johan Sverdrup project in Norway.

The steel riser platform jacket which is being built at Kværner Verdal will weigh 26,500t and would be transported and installed on the Johan Sverdrup field in 2017.

Kvaerner Jackets executive vice-president Sverre Myklebust said: "For Kvaerner’s business area for jackets the work is important for the engineering organisation in Oslo and for our specialised yard in Verdal.

"The prefabrication starts now, and the assembly begins in the first quarter of 2016. The jacket for the riser platform is planned to be delivered in the summer of 2017."

The riser platform will be one of the four platforms to be installed at the at the Johan Sverdrup project.

Johan Sverdrup development project senior vice-president Kjetel Digre said: "We’ve been working thoroughly for a long time making the preparations for this exciting and complex project.

"The steel jacket will also be one of the most complex ever built by the industry. Not only will we route the land-based power through the jacket, we’ll also be controlling the subsea water injection and exporting the field’s oil and gas from it."

Further plans are on the way to tie in future phases of the Johan Sverdrup field development to the riser platform.

Due to its heavy size, the jacket will be shipped out to the field on the 260m Heeremas H-851 barge, which will be received by the quay at Kværner Verdal that is being upgraded.

In addition to the steel jacket, the 246t template for the wells that will be pre-drilled on the field from March 2016 is being produced at Vlissingen in The Netherlands.

According to Statoil, the template should be installed on the field within the next three or four months.

Digre added: "We’ve got an ambitious plan to bring Johan Sverdrup on stream in late 2019 and in accordance with this plan, we’ve now started to produce first building bricks for the project."

The Johan Sverdrup partnership comprises Statoil, Lundin Norway, Petoro, Det norske oljeselskap and Maersk Oil.
