Technip has been awarded an EPCI contract for the subsea development of the Dvalin (previously named Zidane) field by DEA Norge AS. The Dvalin field development is a tie-back from a new 4-slot template to the Heidrun platform through a 15km long Pipe-in-Pipe production line. The development also connects the Heidrun gas export from Heidrun to the Polarled Gas Transport Pipeline through a new 7.5km pipeline. The contract includes engineering, procurement and installation of the pipelines, spools, riser bases and PLEMs (pipeline end modules) as well as rock installation and commissioning scope. Also included in the contract is the installation of a control umbilical between Heidrun and the Dvalin template.
Offshore installation will be carried out in 2018 and 2019 by Technip’s own vessels, including the state-of-the-art reel lay vessel Deep Energy for pipelay and North Sea Atlantic for umbilical installation. The project will be managed from Technip Norge’s offices at Lysaker, Norway, with pipe fabrication at the Orkanger Spoolbase.
