Construction work has commenced at what is being called the biggest industrial project in Norway for decades to come.

Norway’s state-run Statoil said Monday that production of the first elements on the Johan Severdrup project has started. Kvaerner metal worker Stian Myrvold Green started up the machine that will cut the steel for the riser platform jacket on the Johan Sverdrup field.

Johan Sverdrup is one of the five largest oil fields ever discovered on the Norwegian continental shelf, holding estimated reserves of between 1.7 billion and 3 B/Boe.

The Norwegian major and its partners outlined the development plan for the field in early 2014. The company estimates that Johan Sverdrup should yield $200 billion in revenues over the next 50 years. Once in full production, the field should represent as much as 25% of all Norwegian petroleum production. Peak output is anticipated to be as high as 650,000 boepd.

Statoil Senior Vice President for the Johan Sverdrup development, Kjetel Digre, hailed the start of “construction on one of the biggest industrial projects in Europe.”

The steel jacket now being constructed at Kvaerner Verdal will weigh 26,500 tonnes, making it the largest steel jacket in Europe.

Digre continued, “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. In addition, we’re also preparing to tie in future phases of the Johan Sverdrup field development to the riser platform. In building this jacket, we’re in fact making preparations to take in as many as 56 conduits.”

The steel jacket for the riser platform will be transported and installed on the Johan Sverdrup field in 2017. Because of its size, the jacket will be shipped out to the field on the largest barge in the world designated for this type of transport, the Heerema H-851. In order to receive the 850 foot (260 meter)-long barge, the quay at Kvaerner Verdal is being upgraded.

The steel jacket is not the only Johan Sverdrup element now under construction. The 246-tonne template for the wells, to be pre-drilled on the field from March 2016, is being produced at Vlissingen in The Netherlands. The well template will be installed on the field in the course of the summer/autumn 2015.

Digre said, “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 start date of 2019 is a year later than originally scheduled. In April, the government said the postponement left Norway short of its 10-year reserve growth objectives.

The Johan Sverdrup partnership consists of Statoil, Lundin Norway, Petoro, Det norske oljeselskap and Maersk Oil. The partnership has recommended that Statoil be operator for all the field’s phases.
