Equinor opened its country office in South Korea in 2014, and has been supporting the teams supervising the construction of topsides for the Mariner and Aasta Hansteen platforms, the Aasta Hansteen hull, two Category-J rigs, two platforms for Johan Sverdrup, and now offshore wind.

Offshore wind in South Korea

South Korea has large potential within offshore wind and offers attractive opportunities, transforming its energy mix from nuclear power and coal to renewable energy. 

The share of renewable energy in South Korea’s power production is predicted to increase to 20% by 2030; aiming to add 49GW to its renewable production capacity by 2030, of which solar power accounts for 31GW and wind power 16GW. 

Equinor has started conducting wind measurements needed to further investigate the possibility of developing and constructing a floating offshore wind project off the coast of Ulsan in South Korea.  

Building our rigs and platforms

Our activities in South Korea focus on the construction of the vast platforms and vessels used to find, produce and transport oil and gas. Several of these installations have been built at South Korean shipyards:

  • Mariner topsides constructed at Daewoo Shipbuilding & Marine Engineering (DSME) on the island of Geoje.
  • Two category J drilling rigs for the Oseberg and Gullfaks fields constructed at Samsung Heavy Industries (SHI), also on Geoje.
  • SHI delivered the Valemon topside and Heidrun FSU, and is currently fabricating two out of four topsides at the Johan Sverdrup field.
  • The Aasta Hansteen topside and hull were constructed at Hyundai Heavy Industries (HHI) near the city of Ulsan.

Equinor has personnel in South Korea to supervise all these projects. South Korea has previously delivered the following constructions: Gina Krog topside and Mariner FSU (in June 2016), the Valemon topside (delivered in June 2014), the Heidrun storage vessel (delivered in March 2015) and hulls for the Gjøa, Kristin and Åsgard B platforms. DSME has also built four category D rigs for the owner Songa. They have been designed by and will be in operation for Equinor.
