Open Construction Sites Day – a unique chance to visit the Nemo Link converter station

Over a distance of 140 km and at depths up to 50 m, Elia, the Belgian high-voltage electricity transmission operator and its UK counterparty, National Grid, are working at the first electrical interconnection between Belgium and the UK: Nemo Link.

You are curious to learn more about these works and about the advantages of such an interconnection?

Come to the Nemo Link converter station in Bruges on Sunday 6th of May and discover how we convert alternative current into direct current and reverse.

The converter station is the landing point of the cables and there, the electricity is ‘prepared’ for the transportation between both countries. Learn more about the project here.

A walking tour with information panels and ‘good-to-know’ stories will take you through the stories of transformers, interconnectors and subsea cables.

Hereunder you can have a look at the tour:

Belgian land cable delivered on site in West-Flanders

Several key cable work related milestones have been achieved in 2017 on the UK side. The land cable works UK are now almost completed and the submarine cable has been layed in the UK section.

The Belgian land cable works also started picking up pace and started early September!

The land cable itself has been shipped from the Port of Kinuura, located in the Aichi prefecture of Japan, on September 27th. After a long sail, it has arrived at the Port of Zeebrugge on November 20th, where the 32 cable drums containing the 2 times 8850m of land cable have been loaded out.

1,000,000 man hours without any lost time injuries

During September the Nemo Link project reached 1,000,000 man hours worked without incurring any lost time injuries to date!


Nemo Link’s SHESQ Manager, Craig Silcock, is happy to announce this very positive piece of news and comments:
“This is an excellent achievement considering the complexity and breadth of our project and is a direct result of the hard work, effort and safety focus from our team and that of our contractors, and demonstrates the world class safety standards that we uphold. We mustn’t allow this milestone to make us complacent however, and the completion of the construction phase in a safe manner remains a priority for all organisations involved.”

Nemo Link’s first 59km long 400kV HVDC submarine cables loaded on one of the Installation Vessels: the Maersk Connector

After multiple seabed surveys, the disposal of UXOs, the clearance of out of service cables, and diverse other seabed preparation activities, Nemo Link is now ready to start its cable installation activities with its contractor J-Power System –a division of Sumitomo Electric – and its subcontractor DeepOcean.

The first lot of cables, destined to be laid in the UK- and part of French waters, has arrived from Japan early August. Since then, it has stayed at the Port of Blyth, UK, to be loaded out from the cable transportation vessel to a cable installation vessel.

This load-out operation has successfully been achieved and the installation vessel, called Maersk Connector, is now on her way to Pegwell Bay (Kent, UK) where cable installation will commence shortly.

The cable laying works will be carried out by two vessels: The Maersk Connector and the BoDo Installer.

Diagram Cable Installation Activities

Once the Maersk Connector arrives at Pegwell Bay, it will transpool part of the cable (9km) to a cable installation barge, called the BoDo Installer. The BoDo installer will complete the shallow water lay and trench in the near shore area. It is anticipated the installation barge will then ground and the cable will be pulled out on the beach.

In the meantime, the Maersk Connector will start laying the cable in the offshore waters. The cable lay is operated at a speed of 350m per hour. Once laid, the cable will be buried by the trenching support vessel, Havila Phoenix and the T3200 subsea trencher. The trenching support vessel will follow the cable laying vessel to minimize the duration of exposed cable and the use of guard vessels.

The cable installation operations mobilize multiple vessels and lots of other resources. They are impressive to watch, and therefore Nemo Link will share many pictures in the coming weeks!

Public Information Event @ Ramsgate Royal Temple Yacht Club

A public information event has been organized in Ramsgate, on August 17th, to update locals on the construction progress of the Nemo Link interconnector.

We have been busy working on the construction of the UK and BE converter stations and electricity substations. On the UK side, we have been laying cables between the UK converter station site at Richborough and Pegwell Bay, through the country park. This had to be done before the trigger of the next phase of works: the submarine cable installation in the UK and part of French waters.

Before starting these critical operations, the Nemo team has judged it was important to share achievements and coming challenges with the stakeholders and populations in the UK.

The main topic of the information session has been survey and investigation works which were undertaken to assess the safety of the cable route – ensuring it is clear of obstruction and will not impact upon any artifacts of archeological importance. This work uncovered a number of items of archaeological interest and unexploded ordinance, and we have displayed information about our findings. Alongside that information, detailed explanation has been given on the next steps of the construction.

Members of the Nemo Link team were available throughout the event to answer any questions.

Green lights on all permits for the Belgian onshore cable works

On a large project such as Nemo one of the main challenges/hurdles is obtaining all the necessary permits for the construction works.

After hard and consistent work, Nemo Link has now obtained all permits/planning permissions for the construction works related to the Belgian onshore cable route:
- Road permit;
- Building permit;
- Declaration of public use.

The Belgian onshore cable works can now start in September 2017 in line with planning.

Cable Route BE

For more information about the cable route:

The two cables for the 400KV DC Nemo Link will be installed in two parallel pipes over a distance of 8.850 m from the beach side of Zeebrugge to the new converter station in Herdersbrug.

The converter station, located at the Pathoekeweg 302 in Brugge is now in construction.

There are eight horizontal directional drills involved to cross the dune, nature reserve, roads and railway. The longest drill is 538,5 meters. The cables will be pulled through the pipes and interconnected in 15 joint pits.

If you are interested in consulting the permits, please fin them on the ‘download documents’ page.


Stakeholder information event in Richborough

On the 17th of March 2017 Nemo Link held a public information event in Richborough at the Baypoint Club.

The aim of the event was to give local stakeholders the opportunity to engage with the Nemo Link project members. Representatives of the Nemo team, the cable contractor, their construction partner and community consultation specialists were available to answer questions about the project and its benefits and also to explain the plans and the chronology of the land works to be completed in the region of Richborough.

Richbo Stakeholder Event 2

In order to reach out to the population invitation letters (over 3000) were mailed to residents and local businesses. Relevant Portfolio Holders, Ward Councillors, Parish Councillors and site MPs were also invited to the event. Moreover, the event has been advertised in the ‘East Kent Mercury’ publication.

The Nemo team is grateful to those who attended the event as they have contributed to the development of the project. Interesting comments, questions and proposals have been brought up.

Making sure that the local stakeholders are well informed about the project and how the works will occur is a priority for Nemo Link.

Favourable response from the city ‘Brugge’ for the realisation of the belgian land cable works

The Nemo Link conversion station and land cable route are on the territory of ‘Brugge’, the capital city of West Flanders.

The direct current cable land connection will run between the Nemo conversion station in Herdersbrug and the beach of ‘Zeebrugge’.

The city of ‘Brugge’ now has given a conditional favourable response for the realisation of the belgian land cable works that will start later this year.

The governmental department ‘Ruimte Vlaanderen’ can now process the building permit application and provide a final decision.

This is one more positive achieval for the realization of the Nemo construction works.

New ‘slip-form’ constructed firewall for the Herdersbrug converter site

During February some exceptional works have been undertaken on the Herdersbrug converter site.

The Austrian enterprise Gleitbau ( has been put in charge of the construction of a slip-form wall, which will serve as a fire wall between our transformers and the Converter Hall.

Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is poured into a continuously moving form. Slip forming is used for tall structures (such as bridges, towers, buildings, and dams), as well as horizontal structures, such as roadways.

The reason why BAM/Siemens have decided to use “slip-form” technology is that it provides a considerable time advantage. This technique has rarely been seen in Belgium, but allows delivering a high quality solution in a relatively short time frame.

The aim of the wall in question is to minimize the risk of fire in the Converter Hall. The wall is 0.5 m thick and 17m high; it has been built at a speed of approximately 3 m every 24 hours.

This represents a big step for the Herdersbrug construction works.
