Aker will build a 300-ton subsea template for four wells and also will build the umbilical to be connected with the Heidrun platform. Dvalin, formerly Zidane, is in PL 435 about 15 km northwest of Heidrun.
DEA also let a contract to Aibel to ready the Heidrun platform to receive production from Dvalin. Aibel will build a 400-tonne injection system and a 4,000-tonne module for gas treatment. Aibel said they are to be installed in 2018 and 2019, respectively. Construction work will be carried out at the Aibel yard in Haugesund, Norway.
Topside modifications for tie-in of Dvalin to Heidrun will be planned and executed by the Heidrun operator, Statoil ASA.
DEA Norge is operator of PL 435 with a 40% share. Edison SPA, Maersk Oil, and OMV AG each have 20%.
DEA recently submitted the plan for development and operation for Dvalin to Norway’s Ministry of Petroleum and Energy (OGJ Online, Oct. 3, 2016).
