ONE-Dyas lets subsea power cable contract for N05-A platform

ONE-Dyas BV has let a first contract to N-Sea Group to install a subsea power cable between the Riffgat offshore wind farm and the proposed N05-A gas production platform, which is expected to be the first Dutch offshore gas treatment platform in the North Sea to run entirely on wind energy (OGJ Online, Sept. 28, 2022).

Scope of the contract includes survey, design, supply, engineering, transport, installation, burial, termination, and testing of about 10 km of subsea cable. Final permits were received from the Dutch Government in June 2022 followed by a final investment decision in September 2022. Preparations have started and N-Sea will mobilize various spreads in Summer 2023 and 2024 to execute work ahead of a plan for first gas delivery by August 2024.

N05-A is part of the Gateway to the Ems (GEMS) area in the North Sea, about 20-100 km north of the mouth of the River Ems, where ONE-Dyas and partners Hansa Hydrocarbons and EBN are developing gas production destined for both Dutch and German markets. 

The proposed platform lies about 1.5 km from German waters. The expected volume to be produced from N05-A field and surrounding prospects is 4.5-13 billion normal cu m. Potential for the wider Dutch-German GEMS field has been estimated at 50 billion normal cu m, depending on exploration success.
