Technip lands subsea work on Dvalin

Oil and gas company DEA has now awarded the EPCI (Engineering, Procurement, Construction, and Installation) contract for the smaller structures and pipelines, as well as the subsea installation work of the Dvalin development, off Norway, to Technip Norge.

DEA said on Tuesday that the contract with Technip includes the fabrication of smaller structures, the 12/16-inch pipe-in-pipe production flowline, the 12-inch gas export pipeline and the installation of pipelines as well as all subsea structures and umbilical for the Dvalin field.

“This contract is another major element for the Dvalin field development. We will now start to collaborate closely on the details with all companies we have on board, to continue the efficient work on the project,” says Hans-Hermann Andreae, Managing Director of DEA Norge.

“The Dvalin license has awarded contracts with a value of 530 million EUR (4,5 billion NOK) over the past days. These contracts will create hundreds of jobs in a demanding time for the supplier industry,” says Andreae.

To remind, following a submission of the Plan for Development and Operation (PDO) for the Dvalin field to the Ministry of Petroleum and Energy in Norway, DEA awarded a contract to Aker Solutions to deliver the subsea production system, maintenance, and services at the Dvalin natural gas development. DEA also awarded a contract for the modification assignment to ready the Heidrun platform to receive the production from the Dvalin field to Aibel.

DEA added on Tuesday that, later in the project phase, several other contracts will be awarded, among others a contract for the drilling of four production wells.

The development cost is estimated to 1.1 billion Euros ($1.22M), with planned production start in 2020. Dvalin will be developed with a four wells subsea template, which is connected to the Heidrun platform. At Heidrun, the gas will be partly processed in a new module, before the gas is transported in a new export pipeline to Polarled, going to the Nyhamna onshore gas terminal. At Nyhamna, the gas will be processed and transported to the European market.

Recoverable reserves of the Dvalin field are estimated to be around 18.2 billion cubic meters gas and 0.4 million cubic meters of condensate. The field is located in PL435, blocks 6507/7/9 and 6507/8 in the Norwegian Sea, approximately 15 kilometers north-west of Heidrun and 290 kilometers from Nyhamna in Mid-Norway.

The field is operated by DEA with 50% interest following Maersk Oil’s recent exit from the license. Other partners in the license include Petoro and Edison.


Two Technip vessels


According to Technip, offshore installation will be carried out in 2018 and 2019 by Technip’s own vessels, including the 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.

Technip Norge’s Managing Director, Odd Strømsnes, says: “We are very excited to be given the opportunity to support DEA Norge AS in their first field development in Norway. With our extensive experience in the pipe-in-pipe technology and our well-suited fleet of vessels, we are looking forward to assist DEA Norge AS on this important project.”
