The first of four topsides have been installed at the Johan Sverdrup riser platform on the Norwegian continental shelf.
The riser platform, which is the first of four platforms to be installed in the first phase of the project, handles all exports of oil and gas from the field.
The power converter, which will enable the field to be powered with renewable electricity from shore, will be located on the platform.
The riser platform topside was built by Samsung Heavy Industries in three modules, based on the design and engineering of Aker Solutions.
All the pieces of the platform puzzle were lifted in place by the heavy-lift vessel Thialf of Heerema Marine Contractors.
Statoil project manager Ståle Nordal said construction has taken about seven million hours, and with zero serious incidents.
More than 400 kilometres of pipelines, 200 kilometres of power cables, the drilling platform, two jackets and a bridge will be installed in coming months.
