Milestone for power from shore to offshore oil platform – saves emissions equivalent to 70 000 cars

Onshore converter station for first phase of power from shore for the Johan Sverdrup offshore field in Norway is online.

ABB is supplying High Voltage Direct Current (HVDC) converters for electrification of the first phase of the Johan Sverdrup field development project. The HVDC project is ahead of schedule, and recently achieved an important milestone.

"The good cooperation between operator Statoil, engineering, procurement, and construction contractor Aibel, and ABB has contributed to excellent progress in the project. The onshore converter station is now online and ready for use,” says Borghild Lunde, Senior Vice President, Oil, Gas and Chemicals for ABB in Norway.

The Johan Sverdrup offshore field is located 160 km west of Stavanger in Southwest Norway. The huge field will have an estimated production peak of around 660,000 barrels of oil equivalents per day. To compare, today’s production on the Norwegian continental shelf is less than two million barrels. The first phase of the oil field development consists of four platforms.

It is a large amount of power that will be transmitted to the offshore field when in operation, which will mainly come from renewable energy sources like Norwegian hydropower. For the first phase of the Johan Sverdrup offshore field development, the HVDC-system supplied by ABB has a capacity of 100 Megawatt. To put in into perspective, the power is sufficient to run 100,000 1000-Watt electric heaters at maximum heat.

Cutting cost and greenhouse gasses

Operator Statoil estimates that power from shore to Johan Sverdrup offshore field through the 200 km subsea cable reduces emissions of greenhouse gasses by 80 to 90 percent compared to onboard generation of power by gas turbines. The first phase of the field development project will reduce emissions equivalent of 70,000 passenger cars annually or approximately the entire car fleet of Norway’s ‘oil capital’, the city of Stavanger.

When the entire 300 MW power from shore HVDC systems for phase one and two of the field development project will be put in operation by 2022, operator Statoil estimates total reductions of CO2 equivalent to 200 000 cars. This equals the combined car fleet in the major cities Bergen and Trondheim of Norway.

In addition to reduced emissions, electrification of offshore oil and gas production also includes improved operations, reduced maintenance cost and better health, safety and environment (HSE), such as noise reduction.

ABB provides design, engineering, purchasing, installation, and commissioning of the HVDC systems onshore and offshore for the first phase of power from shore to Johan Sverdrup. The power link will operate at +/- 80 kilovolt (kV) and is scheduled for operation by the end of 2018.
