Riffgat to electrify new North Sea gas platform

ONE-Dyas, together with its partners Hansa Hydrocarbons and EBN, intends to use the Riffgat offshore wind farm to power a new natural gas platform in the North Sea.

The proposed N05-A platform is located in the Netherlands, approximately one and a half kilometres from German waters and about 20 km north of the islands of Borkum, Rottumerplaat and Schiermonnikoog.

A maximum of twelve wells will be constructed from this location, some of which will go to the N05-A gas field and some to a number of adjacent potential gas fields (prospects) that have yet to be proven to contain natural gas. A pipeline will also be laid from the N05-A platform to shore.

N05-A will be the first Dutch offshore gas treatment platform in the North Sea to run entirely on wind energy. A cable will be laid from the N05-A platform to the Riffgat wind farm in German waters for the electricity supply of the N05-A platform.

The Riffgat offshore wind farm is located within the twelve nautical mile zone of Lower Saxony, about 15 km northwest of the East Frisian island of Borkum and thus about 50 km from the coast. The 108 MW wind farm is a joint project of EWE AG and ENOVA and was fully commissioned in 2014. It features 30 Siemens wind turbines with monopile foundations.

Platform electrification, as opposed to using diesel generators, will help reduce CO2 and Nitrogen Oxide emissions. In addition, an electrified platform can be unmanned which offers safety advantages and requires less transportation to the site.

The Ministry of Economic Affairs and Climate (EZK) intends to permit the development of the N05-A gas field. The draft decisions and Environmental Impact Report (EIR) are available for public inspection from April 23rd, 2021 to June 3rd, 2021.

ONE-Dyas considers a domestic supply of Natural Gas to remain a key part of the Dutch energy transition. The Netherlands is committed to a CO2-neutral energy supply by 2050. The Government is also currently reviewing its 2030 offshore wind roadmap which targets 49 TWh of electricity produced annually and making long term plans for 2040.
