Partial electrification of Sleipner approved
The Ministry of Petroleum and Energy has approved a revised plan for development and operation (PDO) for partial electrification of the Sleipner field centre.
Electrification means replacing a fossil-based power supply with renewable energy, enabling a reduction in greenhouse gas emissions. Equinor is fully committed to reducing emissions from our offshore oil and gas production. Here’s how we’re doing it.
The oil and gas industry is largely run on electricity generated on site using gas turbines and currently accounts for approximately one quarter of Norway’s total carbon emissions.
Troll A was the first platform on the Norwegian continental shelf to be electrified, back in 1996.
The Gjøa field was electrified from the very outset. As development operator, Equinor lay a 100 km long cable from Mongstad out to the Gjøa field – the longest alternating current cable in the world at that time.
In 2018, Martin Linge was prepared for electrification through the laying of a 163 km long cable from Kollsnes. Production from the Martin Linge field is scheduled to start in 2021.
The Johan Sverdrup field has been electrified by means of power from land, helping ensure record-low emissions from production. Johan Sverdrup has CO2 emissions of just 0.67 kg per barrel, compared with an average of some 9 kg on the Norwegian continental shelf and 18 kg globally.
Sverdrup phase 2 will also supply other fields on the Utsira High with power from the shore. Plans are also being made to enable the Sleipner Field Centre, the Gudrun platform and other connected fields to reduce their emissions through power supply from the Utsira High.
The next technological milestone will be to supply the Gullfaks and Snorre platforms with wind power through the pioneering project Hywind Tampen, the largest floating offshore wind farm in the world when it starts operating in 2022.
In addition, there is work underway to investigate the possibility of supplying power from shore to the Troll B and C platforms and to the Oseberg field. We are also exploring the possibility of supplying the LNG plant in Hammerfest with power from the grid. Further projects will come in the years ahead.
