Changes were made in the mid-2010s to the two oldest installations in the Eldfisk Complex – 2/7 A and 2/7 FTP – as part of the Eldfisk II development.

Cleaning and securing the two platforms began in 2015, and the offshore work and documentation on land had been completed by 1 June the following year.[REMOVE]Fotnote: Pioner, no 2, “Eldfisk avslutning er i mål”, 2016.

Much equipment and many systems on the two platforms became redundant when new installations were put in place. Shutdowns, cleaning, disconnections and making safe were required.

Aibel was the contractor for this work, and made use of a number of sub-contractors – including IKM.

Most of the equipment was scrapped on the spot, while hazardous waste and safety devices no longer in use were removed in accordance with the relevant procedures. Areas were cleaned of hydrocarbons, de-energised, secured and cordoned off.

Eldfisk 2/7 FTP was reduced to a bridge support between the 2/7 A and 2/7 E platforms, with the exception of a new firewater container installed on the deck.

Many wells were still producing on 2/7 A, but it was turned into a wellhead installation when its accommodation was closed down after 2/7 S became operational with new and modern cabins.

Production on 2/7 A was run from the 2/7 S control room and piped to the latter. All the platform’s redundant infrastructure was taken out of operation.

“The work was conducted within the planned time frame and below budget,” said Kennet Staavi, who led the work. “We can also point to very good health, safety and environmental statistics.”
