HVAC Cable

IFA2 is in the process of installing six HVAC cables. A specialist cable laying barge, the NP 289, will lay one cable at a time in an eastern direction from Chilling to Monks Hill Beach.

The table below sets out the planned position of the NP 289 between 19/07/19 and 23/07/19.

Please note that the estimated position is subject to progress of lay which will depend on weather conditions. We will update you regularly on the cable lay progress.

The barge uses four anchor positions to move. These will constantly change as the barge moves forward. The position of each anchor is marked with a yellow buoy. To ensure the safety of beach and marine users, the four yellow buoys mark a safety exclusion zone. The safety exclusion zone is marked indicatively on the graphic above.

The barge is constantly moving and therefore the safety exclusion zone around it will also move.

Anchor cables run from the barge under the water to each of the four anchor points on the sea bed.

The anchor cables are up to 1000m long and could be tense or slack. The anchor cables are a hazard to marine users and for your safety it is important to remain outside of the safety exclusion zone marked by buoys.

There are two safety vessels supporting the works to help and guide water users. To ensure everyone’s safety please follow the guidance of the safety vessels.

What are we doing in the next three months?

  • The C57 Red Squirrel jack-up barge, is in position in the intertidal area off Monks Hill Beach. The working area for the barge is marked by buoys and is patrolled by safety vessels for your protection; please avoid this active working area.
  • We are completing trenching works and installation until the end of June. 
  • The NP 289 barge is laying HVAC cable between Chilling and Monks Hill beach, as above.
  • Our cable laying barge the NP 289 will be completing the installation of the next HVAC cable by pulling in the end of the cable through pre-installed ducting at Monks Hill beach (between the car park and The Shack café at position E in the graphic above). The installation is due to take place on 21/07/19 over the course of daylight hours.
  • We are floating cable from the NP 289 barge into the water supported by orange floats, which should be clearly visible on the water. Additional safety boats will be on the water for the duration of this delivery to help divert marine users from the floating cable.
  • Please be extra vigilant in this construction area during the installation period. We are very grateful for your patience and cooperation.

HVDC Cable

The HVDC cables linking the electricity transmission systems of Great Britain and France are an essential part of IFA2. We will carry out the work to lay these cables in 2019.

The cables will be buried in the seabed. We’ll install the cables using large specialist vessels which are able to transport and lay long sections of cables (up to 100 km). Some cable joints will need to be made at sea during the installation process.

The current position of the HVDC cable laying vessel, the Cable Enterprise, can be tracked using the MarineTraffic.com tool below.


Cable Enterprise

What will happen in the next three months?

  • The HVDC cable laying activity will resume in the Summer months.

    IFA2 contractors go carbon neutral!

    Working with its contractor I&H Brown, National Grid IFA2 has announced that the carbon impact for the new public open space will be neutral.* As a socially responsible civil engineering organisation, I&H Brown pride themselves on reducing their environmental impact by counteracting its greenhouse gas emissions through a long-term forestry project. Where managed on a long-term basis, forests are seen as greenhouse gas sinks for carbon sequestration purposes.

    As a socially responsible civil engineering organisation, I&H Brown pride themselves on reducing their environmental impact by counteracting its greenhouse gas emissions through a long-term forestry project. Where managed on a long-term basis, forests are seen as greenhouse gas sinks for carbon sequestration purposes.

    The Open Space Development’s carbon footprint and emissions will be offset by planting a mixture of trees in the 620-hectare forest which I&H Brown maintains offsite, in addition to the planting on the Open Space Development (link older article). Since 2013, I&H Brown estimate that through woodland management, they have had an annual footprint offset of -3,950.50 CO2e per year.

    The work being carried out by I&H Brown at the IFA2 site includes the reuse of ~36,000m3 of soil on site. This soil is being used to create the numerous earth bunds that screen the converter station buildings, as well as providing viewing platforms over sections of the Solent Airport.

    David Luetchford, head of IFA2 said: “Our new open space contractor is working hard to deliver the public open space at the Daedalus site. We’re pleased that in partnership with I&H Brown, we will be able to deliver a public open space that has a neutral carbon impact.

    Work is progressing well, and we’re now working to enhance the connectivity of the site by establishing the various footpaths and cycleways throughout the space for the public to enjoy in the future.”

    IFA2 to take part in oyster translocation project in partnership with Southern Inshore Fisheries and Conservation Authority (IFCA) as part of the Solent Oyster Restoration Project

    We have been working with the Southern IFCA to carry out an oyster translocation programme to support local regeneration of the native oyster population in the Solent. As part of the IFA2 project, we have recently funded the chartering of a local fishing vessel in the Lee-on-Solent to Chilling area to collect data on and mitigate the impact to the native oyster populations over the HVAC cable route.

    We have been working with the Southern IFCA to carry out an oyster translocation programme to support local regeneration of the native oyster population in the Solent. As part of the IFA2 project, we have recently funded the chartering of a local fishing vessel in the Lee-on-Solent to Chilling area to collect data on and mitigate the impact to the native oyster populations over the HVAC cable route.


    The Solent Oyster Restoration Project, set up by marine conservation charity Blue Marine Foundation (BLUE), seeks to rebuild the Solent’s native oyster population by restoring habitats in partnership with local fisherman, marine and local authorities and scientists. Through the funding we have provided to the Southern IFCA, local fishermen have been working with BLUE to collect oysters on the IFA2 route. The oysters collected are then moved to broodstock cages where they can contribute towards restoring the once self-sustaining oyster population.


    The native oyster, Ostrea edulis, has been found in the Solent since the 1970s. Historically seen as Europe’s largest self-sustaining flat (native) oyster fishery in its peak, the oyster population has recently declined, affecting fishermen and the overall health of the marine ecosystems in the Solent. Temporary closures of oyster harvesting have been in place in recent years to avoid further loss of the native oyster population and allow remaining adult oysters in the Solent to reproduce and act as a breeding stock.


    Dave Luetchford, head of IFA2 said: “We’re thrilled to be supporting the Solent Oyster Restoration Project. This is a great opportunity to make a contribution to conservation in the Solent, helping to restore to the region’s once self-sustaining oyster population, supporting employment in the oyster fishery and thereby the local economy, as well as improving biodiversity and water quality in the Solent.”
