NPF Oslo/PF Oil Group and ABB have the pleasure to invite you to a lunch meeting to learn about the Johan Sverdrup Power from Shore Project.

The Johan Sverdrup field on the Norwegian Continental Shelf is estimated to have resources of between 1.7 and 3 billion barrels of oil equivalent. After production begins in late 2019 it is expected to rise to a peak of more than 500,000 barrels a day, making it the largest field in the whole of the North Sea. It will also be one of the most important industrial projects in Norway over the next 50 years.

ABB has been awarded two contracts worth around $200 million for the supply and installation of systems and equipment to power Johan Sverdrup.

ABB leads the way when it comes to cable systems that deliver onshore power to fixed and floating platforms. The company has already laid AC cables to a number fields, such as the 162km line to Total’s Martin Linge, which is presently the world’s longest, and the link to the Goliat FPSO in the Norwegian sector of the Barents Sea.

For even more remote fields, direct current power transmission technology is needed. ABB’s solution, which is based on voltage-source converter technology (VSC), is called “HVDC Light”, and it allows the flexible transmission of up to 1.8 gigawatts of electricity over immense distances.

The technology is cutting-edge, but it is also well proven: two HVDC power-from-shore systems have already been implemented in the North Sea, at Statoil’s Troll A platform in 2005 and BP’s Valhall in 2011; it is about to be used for two new compressors at Troll A, and will shortly be delivered to Johan Sverdrup.

When it becomes operational, Johan Sverdrup will hold the world record for the longest extruded submarine cable to an offshore oil and gas production facility: more than 200km. At either end of that cable will be the HVDC stations that will convert electricity from high voltage alternating current (HVAC) to high voltage direct current (HVDC) and vice-versa. The onshore converter station building will be located on Haugsneset in south-west Norway, and the offshore converter module on the Johan Sverdrup’s riser platform.

For the installation of the HVDC cable system, ABB has commissioned the world’s most advanced cable-laying vessel to boost the capacity of its operations while increasing their efficiency and precision.  The 140m-long vessel will be custom-built, and will deploy many of ABB’s own marine technologies. The award-winning Onboard DC Grid, for instance, will use a single DC circuit to handle ship propulsion to reduce fuel consumption by 27%. Meanwhile, top class dynamic positioning and roll-reduction tanks will the improve accuracy of it cable laying and subsea operations will be executed and monitored by a remotely operated vehicle using cameras and sonar.

The vessel will be constructed at Kleven shipyard in Norway and delivery is scheduled for 2017.

Lunch and refreshments will be served.
