“Aasta Hansteen is one of the biggest and most complex industrial projects in Europe. With the Polarled pipeline, the Norwegian gas infrastructure is taken northward across the Arctic Circle for the first time.
We are building the largest SPAR platform in the world, and we are setting a new depth record of 1,300 metres for a field development and pipeline on the NCS,” said Torolf Christensen, Statoil’s head of Aasta Hansteen.
The investments in Aasta Hansteen and the Polarled pipeline total NOK 57 billion (USD 9.21 bn).
The plan for development and operation was approved in 2013, and today the project is under development in several parts of the world.
The hull and the topside are being constructed in South Korea, while the equipment packages and subsea facility and pipeline equipment are delivered globally.
The first offshore work started in the summer of 2014 and involves laying of a fibre-optic cable on the seabed and installation of rocks on the seabed for the pipeline. The project is on schedule for production start-up in the third quarter of 2017.
“The combination of deep waters, harsh weather conditions and a long distance from existing infrastructure on Aasta Hansteen is unique globally.
In order to meet these challenges we have cooperated closely with the supplier industry, and jointly we are developing a new deepwater standard.
The expertise we acquire will be applied in new developments both on the NCS and internationally,” said Helge Hagen, project manager for the Aasta Hansteen subsea development.
