From FEED to implementation

At the end of 2017, Equinor handed out several contracts in connection with the Snorre Expansion project (SEP).

Aibel received the contract for extensive modifications on the Snorre A platform with a value of around NOK 1.6 billion, after having delivered the FEED study for this modification contract. The contract gave Aibel total responsibility for the engineering, procurement, construction, installation and commissioning of the topside facility project.

The modifications included the removal of excess weight and equipment from the Snorre A platform, and the installation of a new 650 ton support module for risers, which was built at Aibel's yard in Haugesund.

The engineering work involved at its peak around 160 engineers based at the headquarters in Stavanger.

The module was mechanical complete on time 1 February 2020, loaded out of the North Sea Hall in Haugesund in the beginning of March, and picked up by the world's largest crane vessel, Sleipnir, in April. The module was then placed on Snorre A, where Aibel concluded the installation work.
