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

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.

What will happen in the next three months?

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

    We were delighted to be one of forty businesses providing activities for 1000 young people at the STEM at The Big Bang @ Solent STEM event in April. Our team worked with students throughout the day to explore and create electrical circuits.

    Jacquie Jones, EBP South Project Manager said ‘The Big Bang Solent is a hugely popular event with schools and businesses. With research showing that the STEM skills shortage costs UK businesses around £1.5 billion per year this is a proactive established event that allows businesses to upskill young people.’

    Jade Fuller, Project Manager of Employment and Skills at Solent LEP said ‘It is vital for employers and businesses to engage their future workforce and Big Bang @ Solent provides a great opportunity for them to do this. The Solent LEP is proud to sponsor events that enable young people to meet with organisations to ensure that they are aware of the future career pathways available to them.’

    The Big Bang @ Solent is organised by EBP South to inspire young people to explore the career opportunities and industries STEM can open up to them.

    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.
