Less CO2 with power from shore

In 2018, Aibel delivered the converter substation, the pump station and associated infrastructure to the power plant at Haugsneset east of Kårstø. The plant supplies the first four platforms on the Johan Sverdrup field with power from shore.

After the successful completion of phase one, Aibel was awarded the contract to build phase two of Equinor’s onshore power plant.

The phase two development contributes to secure the power supply from land to the further development of the Johan Sverdrup field, and also contributes to establishing the area solution for power from shore to the remaining fields on the Utsira formation.

The contract was carried out in cooperation with Norconsult in Sandvika for detailed engineering of the actual building. Aibel itself was responsible for engineering of all technical disciplines, including a comprehensive ventilation system (HVAC) for cooling the converter facility.

Siemens supplied the actual converter components (HVDC), while Aibel was responsible for all other deliveries, including installation of the HVAC and HVDC facilities.

The contract engaged approximately 50-60 employees in the engineering phase in the first year. In the actual construction phase, which started after the summer of 2019 at Haugsneset, around 120 Aibel employees has been involved. In addition, there has been contributions from subcontractors. The completed Power from Shore II plant was delivered by the end of 2021.


Contract: EPC (Engineering, Procurement and Construction)

Client: Equinor

Value: Phase one: Approx. NOK 600 million. Phase two: Approx. NOK 500 million.

Delivery: Phase one: 2018. Phase two: 2021.

At Haugsneset, the alternating current is converted to direct current before it passes through 200 kilometres of power cables to the Johan Sverdrup field. At the field centre, the direct current is converted back into alternating current. This supplies the various installations in the field centre with power from shore, reducing CO2 emissions significantly.

The converter substation in phase two has a doubled capacity compared to the plant in phase one.
