Increasing security of electricity supplies for both the UK and France.

HVAC Cable

IFA2 is in the process of installing six HVAC cables between Monk's Hill Beach and Chilling. This work has been progressing well, we have now laid all of the cables.

We will now bury the HVAC cables and continue to prepare for the arrival of the HVDC cables from France.

What are we doing in the next three months?

  • Our HVAC burial vessel JIF ARTEMIS is burying the HVAC cables beneath the seabed. We expect this work to last until November.
  • Our support vessel, GREEN QUEST, will be in the area assisting JIF ARTEMIS.
  • 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.

What will happen in the next three months?

  • The CAPALL MARA (shown below) is currently completing trenching works up to 2km from shore. Works will continue throughout November to return the area back to normal and make it safe for water users.
  • The final HVDC cable pull-in at Lee on Solent has been completed and The Cable Enterprise is now laying cable through the Solent. This work will be completed by the end of November.

    IFA2 continues school engagement programme at Crofton Hammond Junior School

    We have been visiting local junior schools as part of a wider school engagement programme, and recently visited Crofton Hammond Junior School in Fareham.

    We have been visiting local junior schools as part of a wider school engagement programme, and recently visited Crofton Hammond Junior School in Fareham.

    Craig Hunter, IFA2’s Assistant Commercial Manager, led an assembly with ‘Mad Scientists’, Super Sian and Electric Eddy. 90 children in Year 4 attended the session, which kicked off with a careers talk from Craig on engineering. Super Sian and Electric Eddy then took over, giving insight into the history of electricity and teaching the year group about some of the most famous electricians.

    The children were keen to get involved in an experiment to demonstrate how electric currents are conducted. The Van de Graaff generator concluded the session, and was met with delight from all the pupils!

    As we continue to work on the IFA2 project, we are keen to support children living in the local area, making learning about STEM subjects engaging and fun.

    Our school engagement programme is open to all local primary schools – for more information, email info@ifa2interconnector.com or call 0800 0194 576.

    National Grid boosts offshore safety for IFA2 interconnector

    Combined technology set to detect and protect mariners and cable operations

    National Grid and RTE’s IFA2 interconnector project is investing in a powerful combination of safety and security measures to protect marine users around while it lays high voltage direct current (HVDC) cables in the Channel between March 2019 and February 2020.

    For the first time on an offshore cable project, IFA2 will use a combination of fast response patrol vessels with manned and unmanned aerial vehicles (UAV) linked by satellite to an operations room to monitor its work areas. The UAV will provide high definition images of the working area, and traffic approaching it, every five to ten seconds. The protection package aims to ensure the cable laying exclusion zone is avoided by fishing vessels which could otherwise result in costly damage to both the cable and vessel. This is in addition to the traditional measures of AIS monitoring, safety vessels, Notices to Mariners, and follows consultation with marine authorities and local fishermen in both countries.

    David Luetchford, IFA2’s Project Director in the UK, said: “There have been episodes of damage to both fishing vessels and cables when vessels have ignored notifications and demarcations on previous interconnector projects. We have learned from these.

    “We’ve identified a combination of several technologies and tactics to detect and deflect any vessels in our working zones, thereby ensuring risks to fishing vessels and cable laying are both minimised.”

    The HVDC cables linking the electricity transmission systems of Great Britain and France are an essential part of IFA2, and will run 200km from Merville in Normandy to Fareham in Hampshire. The cables will be buried in the seabed and installed by large specialist vessels which can transport and lay long sections of cables (up to 60km). There will be an exclusion zone extending to 500m either side of the cable route during the laying and burial operations.

    Hook information event

    We’ll be restarting work to install cables for IFA2 in the Chilling area and are hosting an information event where you can find out more about this. The open event will take place from 4pm – 8pm on 12 March 2019 at the Nook and Cranny, Hook Ln, Hook, Warsash SO31 9HH.

    We’ll be restarting work to install cables for IFA2 in the Chilling area and are hosting an information event where you can find out more about this.

    The open event will take place from 4pm – 8pm on 12 March 2019 at the Nook and Cranny, Hook Ln, Hook, Warsash SO31 9HH.

    Last year we installed the ducts which will house the high voltage alternating current (HVAC) cables required for IFA2. We then paused work in November 2018 to reduce the risk of disturbing overwintering birds.

    The season for these birds will soon be over, and we are preparing to begin work in the area again in coming weeks. The focus for our work will be laying and connecting the cables. As before, we’ll impose a 10mph speed limit for construction vehicles through Hook Village, as well as escorting any HGVs.
