The contract involves the construction of the onshore converter building and pumphouse with all necessary equipment. In addition, about four kilometres of AC and fibre optic cables will be laid from the terminal at Kårstø to the converter at Haugsneset.
“We recently delivered our first conversion platform for wind energy to Germany and we previously had major conversion work on the Troll platform. For us, this is therefore an important and natural continuation which consolidates our position in this field,” says Jan Skogseth, CEO of Aibel.
At Haugsneset, the alternating current will be 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 will be converted back into alternating current. This will supply the various installations in the field centre with power from shore. In this way, CO2 emissions will be significantly reduced.
Various locations
The work will be managed from the Oslo office until the detail drawings are complete. Most of the work will then be moved to Kårstø and Haugesund, where prefabrication will also take place. Aibel has engaged Norconsult and Veidekke to ensure expertise in all relevant fields.
"With personnel from Aibel, Norconsult and Veidekke, we are well equipped for this project,” says Nils Arne Hatleskog, Executive Vice President of Field Development.
Work will start immediately and the initial phase will involve about 60 people. The work is scheduled to be completed in September 2018. The contract is worth around NOK 600 million. ABB has been awarded the other two contracts for supply of power cables and rectifier technology.
In February this year, Aibel won the contract for the construction of the deck for the drilling platform on the Johan Sverdrup field.
