Engineering services were provided by Aker Solutions at Fornebu outside Oslo. Steel cutting for the topsides began at Kværner Stord in late March 2012, with fabrication starting during the spring. Part of the prefabrication was done by subcontractors in Finland and Poland.

The topsides were installed in the summer of 2014 on the jacket, which had been constructed by Dragados in Spain and put in place the year before. A bridge connects 2/7 S to Eldfisk 2/7 E. The accommodation were occupied in July 2014.
A new power and fibreoptic umbilical was laid to transfer up to 20MW of electricity between Ekofisk 2/4 Z and 2/7 S. On line from 2016, this improved energy efficiency among the Ekofisk-area fields.

Platform facilities include 40 wells and a process plant. Bridges also connect to the Eldfisk Complex. The unmanned Embla platform is operated from 2/7 S.
The official inauguration of Eldfisk II and 2/7 S was conducted on 23 March 2015 by Kåre Fostervold, state secretary (deputy minister) at the Ministry of Petroleum and Energy.

Helping to maintain oil production towards 2050, Eldfisk 2/7 S replaced Eldfisk 2/7 FTP and the former living accommodation on Eldfisk 2/7 A. The latter remains in operation as a wellhead platform.
