Oil Field/Offshore Engineering Johan Sverdrup Offshore Project: A Giant Comes to Life

| Editor: Dominik Stephan

A giant team for a gigantic challenge: Aker Solutions has assembled one of its biggest engineering teams ever to deliver the initial plans for the engineering and design phase of the giant North Sea Johan Sverdrup oil deposit.

The company is on track to deliver the first draft report due in the fourth quarter, a project that has involved 400 employees in Oslo and London. The work covers all four of the planned platforms for the first development phase, including the so-called topsides, jackets as well as bridges spanning the facilities.

"Johan Sverdrup represents the future of the Norwegian oil industry and we are working closely with Statoil, the operator, to ensure the best possible solution," said Valborg Lundegaard, Aker Solutions' head of engineering. "We have put together our biggest-ever front-end engineering design team for this project and the work is now two-thirds completed."

The current work has been proceeding since Aker Solutions in December received a framework contract from Statoil to provide engineering services, procurement and management assistance (EPma) for as many as 10 years at Johan Sverdrup. The accord includes front-end engineering design (FEED) work building on concept studies that Aker Solutions carried out last year for the deposit. Statoil is the working operator for the development, which spans three licenses. The other partners are Lundin Norway, Petoro, Maersk Oil and Det norske oljeselskap.

Norway's Largest Offshore Find

Johan Sverdrup is the largest offshore oil find in Norway in 30 years and is estimated to hold 1.8 billion to 2.9 billion barrels of oil equivalents. It's seen producing 550,000 - 650,000 barrels of oil equivalents a day when fully developed, equal to about 25 percent of current domestic output. Production is slated to start in late 2019 and is predicted to last for about half a century.

Maturing the Concept

Johan Sverdrup will be developed in multiple phases. This first will consist of a field center with processing, drilling, riser and accommodation platforms. These will be designed with an expansion in mind. They will be linked by bridges and rest on steel jacket substructures that rise about 100 meters from the seafloor.
