Aker BP ASA has let a contract to Heerema Fabrication Group Vlissingen for procurement and construction of the Munin jacket in the northern part of the Yggdrasil area in the North Sea.
Munin is an unmanned production platform. The jacket weighs 5.800 tonnes and is 130 m high. It will be installed in a water depth of 105 m. Eight 60-m piles will be used to secure the jacket to the seabed. Aker Solutions will do the detailed engineering of the jacket, and Aibel AS is delivering the topsides.
The jacket contract was signed on May 25. Jacket procurement will start later this year, with construction set to begin early 2024. The jacket will be fabricated at the Heerema yard in Vlissingen in the Netherlands. Installation is planned in 2025 and Aker BP has secured lifting capacity for all the installations in the Yggdrasil area.
Yggdrasil is a comprehensive subsea development with a total of nine subsea templates. The plan calls for 55 wells in the area, which will be developed using power from shore (OGJ Online, Mar. 23, 2023). Yggdrasil, which lies between Alvheim and Oseberg in the North Sea and contains total recoverable resources of around 650 MMboe, consists of Hugin, Fulla, and Munin license groups. Total investments are estimated at NOK 115 billion.
In December 2022, Aker BP and license partners Equinor Energy AS and PGNiG Upstream Norway AS (formerly LOTOS ) made a final investment decision to develop the Yggdrasil area and plans for development and operation were submitted to the Norwegian Ministry of Petroleum and Energy (OGJ Online, Jan. 9, 2023).
