Road Deviation

During the 8 850 m land cable installation works, some roads will be shortly closed.

Works are being processed in multiple phases, to minimize the burden.

Nemo Link provides traffic boards, indicating how the road is temporarily deviated

General Information

How long is the belgian onshore cable?

The Belgian onshore HVDC cable is 8 850m long. Of those 8 850 m, 2000 m are Horizontal Directional Drills (HDD).

HDD is a steerable trenchless method of installing underground cables in a shallow arc along a prescribed bore path with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings.

On the Nemo Link Belgian land cable route, there are 8 HDD. The longest is about 538 m long.

Where will the land cable run in Belgium?

Geographical Overview Herdersbrug2

How will the cable be installed?

First, a trench is made in the road, two ducts are installed and then the trench is closed again, with a small exception for the ultimate part.
After this is done, we start making the connection pits in sequence about every 600 m. Two cables are pulled through the ducts. The cable interconnections are made in the pits, which are then covered.

How long will it take to finish the cable installation?

The installation is made of two phases. We first install the ducts in sequence. The operation has started early September 2017 and it is expected to end Q1 2018.

The second phase consists in pulling the cable in the ducts and interconnecting it in sequence. These works are likely to start in Q1 2018 and to end Q2 2018.

Following that, there will be a final road repair, planned for Q3 2018.

Mitigation Measures

Nemo Link has put in place and engaged to respect 7 measures to mitigate the nuisance and inconvenience of the works, they are as follows:

  1. Modern design technologies and materials limit the visual and noise nuisance during the works.
  2. To instal the cable, the subcontractor will dig trenches on the roads. The width of the trenches is reduced as much as possible.
  3. The installation of ‘waiting tubes’ allows the works to progress at a speed of 30 to 40m a day.
  4. Thanks to the temporary finishing, the road will stay accessible.
  5. Between October 2017 and June 2018, ‘Groendijk’ and ‘Patentenstraat’ will be partly closed to traffic. During this whole period, Nemo Link will provide traffic boards, indicating how the road is temporarily deviated.
  6. Nemo Link will inform local residents, entreprises and other stakeholders on a regulary basis during the project (*).
  7. During the planning and construction phases, Nemo Link team members will gladly answer all your questions.

 

(*) What will be put in place to inform residents about the works?

In collaboration with the subcontractor who has been awarded the land cable works (Verbraeken Infra) Nemo Link has put in place some actions to inform the residents of the works.

  • Send-out of personal letters to every resident in the concerned zone,
  • Visit to residents to solve any local constraints,
  • News and updates about the works weekly,
  • Spontaneous and informal communication during the works.
