N-Sea to install subsea connection between Riffgat OWF and new N05-A gas production platform

N-Sea will supply and install the subsea power cable that will connect the Riffgat offshore wind farm with the new to be built N05-A gas production platform. The subsea cable will allow the platform to operate by electrical power.

N-Sea received the contract from ONE-Dyas, the largest private upstream oil and gas company in the Netherlands. The scope includes the complete scope comprising of survey, design, supply, engineering, transport, installation, burial, termination and testing of the subsea cable asset with a route length of approx. 10km. Final permits were received from the Dutch Government in June 2022 followed by a final investment decision in September 2022. The preparations have started straight away and N-Sea will mobilise various spreads in Summer 2023 and 2024 to execute the works in order for ONE-Dyas to deliver first gas by August 2024.

The subsea cable will allow the N05-A platform to operate by electrical power from the Riffgat offshore wind farm and will not only be the largest investment in a natural gas development project on the Dutch continental shelf over the last 15 years but also the one with the lowest emissions footprint in the North Sea. In addition, the production of domestic natural gas will contribute to the security of supply and support the Energy Transition for The Netherlands.

N-Sea is proud to be selected by ONE-Dyas for delivering a significant part of this major development and aim to execute the project in a professional, safe and responsible way.

“N-Sea appreciates the trust offered by ONE-Dyas to award such a strategic important project with ‘green credentials’ to N-Sea. We fully support the ongoing Energy Transition in the Netherlands and believe this project to be a prime example of reducing emissions whilst improving the security of supply of Natural Gas. N-Sea looks forward to a good collaboration with ONE-Dyas and its Dutch supply chain partners to deliver this project in a safe way.” said Jack Wattel, Director Subsea Cables N-Sea.

GEMS project

GEMS stands for ‘Gateway to the Ems’ and referes to an area in the Noth Sea, about 20 to 100 kilometres north of the mouth of the Ems. In this area, ONE-Dyas, together with partners Hansa Hydrocarbons and EBN, is investigating gas production opportunities. This development of gas field N05-A is part of this. The expected volume to be produced from the N05-A field and surrounding prospects is 4.5 to 13 billion nm3. The potential of the wider Dutch-German GEMS area has been esti,ated at around 50 billion Nm3 in total, despending an exploration success. Gas field N05-A is also partly located in Germany, the natural gas is therefore destinated for both Dutch and German natural gas demand. Contracts with German companies will also be signed for this Dutch-German project. Source: N-Sea
